I have made some progress on the basement, and thought I would share with everyone who has posted on this thread. I'm anticipating late April to complete the theater. I hope you all enjoy the picture. :D
The front right and left are 56deg apart, and the rear channels will be at 105deg to each side. All horns are centered at 48 inches above the subfloor, and the screen will be perforated.

You might want to make sure all of your duct work is damped??? Or you will regret it later.:(

Everyone,

I have been negligent in posting, and I'm sure many want to see the results of my effort. I'm not quite finished yet, but the Urei's have been moved to their new home, and I couldn't wait to share. Enjoy!

I'll be cutting the wood for the 2242H's this week, so hopefully the bottom holes will be filled before long.

Things will look better once the holes are filled, and the trim is up. More to come......

David,

I would like to add, soffit mounting the Urei's made a HUGE differance in the transient response. The system has much more "punch" to it now, and the low end is incredibly smooth (no boomy bass). If it is an option, I would highly recommend mounting your Urei's in soffits, I was not prepared for the improvement, absolutely amazing! :)

Frederick

Understand about the soffits, Fredrick. They were clearly designed with that assumption/requirement.

I've just moved back into a house where I'll end up setting up the garage for use as a 'romper room'. Right now, the UREI's are on furniture mover's wheels and will stay like that for a while. Yes, there's a bit of booming in the bass but the midrange presentation is all there. I posted a picture of the current setup the other day somewhere on these forums.

I *could* almost set up a smaller version of your theater in there, using the 809s for rear speakers and the set of JBL 4425s for a middle, I suppose. Nah.....I'm just into 2-channel right now. Maybe someday.:blah:

The other problem I have here in Santa Cruz is that the houses are on 40' x 80' lots. Houses are close together as a result and I can already hear the 813s out on the street through the garage door. Can't imagine what a full theater setup would do for the neighbors' entertainment.

One interesting thing I discovered re: light bulbs in the UREI's. The tweeter bulbs in the crossover are GE-81s. They're the same bulbs as found in old Volkswagen dashboard lights - the old 6V versions from the 60s, that is. Was able to locate them at a local VW restoration outfit. The other 6V bulbs for the woofers I found at a local lighting fixture company after digging around in their old boxes. They had *lots* of them.

For the large spade connectors on the back, I used Thomas and Betts L35-B2 copper terminal lugs, available at Home Depot. These allowed me to use its clamping system while making a solid connection to the speaker.

Cheers,

David

Nothing wrong with 2 channel....most can't get that right, and going multi-ch without getting 2 channel right, is just wrong. ;)

The room may look bigger than it really is. It's only 19.5 ft deep, and 14 ft wide. You may have more room than you think.

I did see the pics of your Urei's. Definately nice.

I have the wood cut now for the 2242's, hopefully I'll get them somewhat together this weekend.

Here's a pic of my 811Cs when I first got 'em home and hooked them up for a test drive. I love my UREIs. I was first exposed to them at the '83 Audio Engineering Society Convention in NY. I'm doing up a page to describe how and why I managed to bring home these old friends after mixing on 813Cs for twenty years and this particular pair of 811Cs for ten years. I've also started a page showing the pics of UreiCollector's rig, just to show that I'm not exactly batty in loving these things, at least by comparison... :D I could point you to the pages if you are interested.

By the way, UreiCollector, I'd love to hear your observations comparing the 811As to the 811Cs, as well as comparisons of the 813A and B series. :)

Bob

PS, Interestingly, my 811Cs replaced a pair of Audio Techniques Big Reds in '92 and our 813Cs replaced a pair of Altec 19s in '86.

UreiCollector
09-25-2006, 01:28 PM
Gee those look nice! I like the sound of the C's a lot....my impression is that they have more attack in the midrange, but I have not listened to them in the same room as the A's (or B's) for that matter. So it could be all room effect.

I sure hope you found some nice soffits for those 811's to live in. :)

Bob Womack
09-25-2006, 05:23 PM
Actually, they are living against a wall. The bass response of our soffitted 813s is smoother than the subwoofed 811Cs, but I think the subwoofers actually extend the low end a little further on my home set.

WOW! Awesomely speechless! Out of this world!:applaud:

The Baffle wall is the way to do it!

Like the THX professional baffle wall, the front of the wall is covered with sound absorbent material to stop the high frequencies bouncing of the perforated screen, otherwise, the result will be a very bright sound, this also helps for intelligible dialogue.

I havn't done anything special for the center. I am considering some acoustic foam on the front wall between the speakers, but am undecided.

To my supprise, the screen is remarkably transparent. I wouldn't say it's acousticly "invisible", but I have to admit I was pleasantly supprised with how little it seemed to have colored the sound.

The moire effect on the picture is far more distracting than the minor (in my opinion) acoustic affects of the screen. I can see "ghost" images due to reflections of the image off of the wall behind the perforated screen.

clmrt
12-04-2006, 07:06 AM
Bummer. What's the solution for that I wonder. Black felt?

Edit - Oh yeah - awesome theater by the way. I'd do the same thing in a heartbeat. Except I'm a sucker for black / dark walls and carpet. Maybe black carpeted walls with reflective surfaces added to taste.

Like I even know what I'm talking about.

UreiCollector
12-05-2006, 01:54 PM
Thanks for the kind comments.

I thought about black felt, but I'm not sure I'd like the apperance (lights on). I'm torn, as always. I'm going to start with a darker shade of the wall color in flat paint, and see what kind of results I get. If i'm still not happy, then I'll try something else. Perhaps a carpet of sorts on the front wall....but I don't if I'll be happy with the apperance.

It's a tough situation, but compromise is the name of the game. Having the center channel directly behind the screen is well worth this trouble though, I wouldn't do it differently.

Considering I use this room for listening 90% of the time, and movies 10%, it hasn't been bothering me much. :) The lack of trim around the Urei's is more irritating at this point.

Cheers! Frederick

My eyes are drawn to the racks - the so-called "outboard" gear - particularly the shiny faced pieces. Tell us what you got - particularly the upper two 1RU racks?

It looks somewhat like "all Behringer all the time"... ;)

UreiCollector
11-24-2008, 07:09 PM
hey Bob!

The two silver boxes at the top of the rack are Behringer Multicom compressors....I use them when watching movies with my wife (she can't handle the dynamic range, and I hate playing jockey with the volume control). When watching movies on my own they are set to bypass....and they are only in the audio path when watching DVD's or BluRay, CD goes straight from my CD/DVD/Super Audio player to the analog preamp.

As for components, at the very top of the rack is a DVDO iSCAN HD+ Video Scalar, the compressors next, a Sony TA-P9000ES analog preamp, Sony TA-E9000ES processor, Sony DVP-S9000ES DVD/Super Audio Player, PlayStation 3 for BluRay, Outlaw ICBM for bass management (multichannel crossover), Behringer DCX2496 Ultradrive (used on the subwoofers ONLY for EQing, and high passing at 20hz), a Behringer DEQ2496 (used as an SPL meter only), and Hafler Amplifiers round out the bottom (DH500 for mains, DH220 for center, XL280 for surrounds {sits in the closet, no rack space}, and a Hafler GX2600 for the JBL 2242H subwoofers). The computer in the equipment room has CLIO on it for when I get the urge to tweak the system.

The man has 4 of them (811C's)......

I was a little surprised that he swapped it out for the 6332....especially considering he doesn't hear so well above 4kc. They do image better than the Urei's....and that may be why he went to it.

The 6332's are amazing, I have to say.

Interesting. I had thought of doing the same myself - different gear ;) , but same application. Curious - what is the threshold and ratio. Any make-up gain?


Behringer DCX2496 Ultradrive (used on the subwoofers ONLY for EQing, and high passing at 20hz)...Hmm...

So, what is the signal path like - are there passive crossovers in each cabinet? (the DH500 for mains, DH220 for center, XL280 for surrounds are all "full-range cabinets? I'm a bit confused...)


...subwoofers are EV180B's...If your dad likes the EVX180B's, he should try JBL's 2242H. It will slip right into that mouting and will literally blow-away the EV's - both in response and quality. Oh - and I think I like your dad a LOT!! :rotfl:

For the compressors I've set the threshold around -34, the Ratio to about 10:1 (give or take), and I'm not using any make up gain (the compressors only start doing their magic during loud passages....for 90% of the duration of a movie, it's pretty much unity gain). I set the TA-E9000ES to -30 when running movies with the wife, and all those settings together keep her from squaking about the level, and keep me from jockeying the volume control....these are the settings I've come up with over about 6~7 movies with her.


As for signal path....for DVD / BluRay movies.....

DVD Player => P9000 (processor) => Compressors => E9000 (analog preamp in bypass mode) => Outlaw ICBM (high pass at 60hz) => Haflers => Urei's (using factory passive crossovers)

for the subwoofer section i come out of the Outlaw ICBM (now low passing at 60hz with all channels summed plus LFE)=> DCX2496 (digital crossover with EQ and 20hz high pass at 6db/octave) => Hafler GX2600 => JBL2242H's

For CD audio and Super-Audio the CD/DVD/Super Audio player uses analog outputs directly to the E9000 analog preamp (now in active mode).....and all else remains the same down the chain. ((pure analog signal path from the output of the player to the speakers, with the exception of the subwoofer path due to the DCX2496))



As for dad with his EV180B's.....I've tried to push the JBL2242H's (which I use) on him, but he's happy with the EV's, so who am i to argue? Heck, he has enough of them to make up for any defecits......


Hope this helps clear things up.....i can always draw a pic tomorrow to make it all crystal. :D

How much of this complex gear is used power wise, decibels, volume, presence, image whatever you 'experts' call it, to actually emulate the surroundings in a state of the art retail cinema? Is master volume on '1' or can you drive it much higher and still keep your sanity? Decibel level for your listening? Depends on movie selection? Movie favorites so far?

Is master volume on '1' or can you drive it much higher and still keep your sanity? Decibel level for your listening? Depends on movie selection? Movie favorites so far?

I've done my best (within my limited budget) to make the room as neutral as possible. As for emulating a 'retail cinema', I didn't even think about that....I was aiming for the best configuration I could achieve in the limited space that I had. My personal feelings are that my home cinema far exceeds any 'retail cinema' that I have ever been in.....the sound is by far better, the picture phenominal (considering I'm using a $1200 projector....it could be better), the seating is by far more comfortable, and the overall impact is far superior.

Low frequency impact for example, trumps any retail theater I have been in....the low end in my room is much deeper and has much more impact. Of course, I'm only filling a 6 seat cinema with sound.....not a 200+ seat space. When Neo fires that gatling gun in "The Matrix" for example, you can feel every single shot through the seat of your pants.....I never had that experience out at a retail cinema.

As for any type of audio processing to emulate a space.....I do not believe in using any of those 'features'. They never sound right. The only EQ'ing I'm using is below 60~80hz on the subwoofers. I've done my best with acoutic treatment of the room to make the sound as neutral as possible.

To the point of listening level......when I watch movies alone, I'm running at much higher levels than at a 'retail cinema'.....I just like it that way.....my wife on the other hand thinks it's way too loud....so I run at much lower levels when she is in the room. I have never measured the SPL during a movie, but if I were to venture a guess, I'd say I'm averaging in the 80's~90's somewhere with peaks well over 100.....but that's only a guess. For CD listening, my average is 90+.....I like my music loud.

Favorite movies: The Matrix, X-Men, Costantine, Cars, and The New Battlestar Galatica.

Sorry, my bad. That was a meaningless way to ask the question: How much gain reduction do the "loud" passages get? 10:1 is a great deal higher than I would have thought.

Question: since the C/L's are in the signal path all the time, are they clean sounding? Have you ever measured their signal characteristics, or listened closely with headphones A/B...? I ask because I've found that lower price-point units can degrade the signal, audibly. As example, in the performing world there is a Boss guitar tuner everyone loves, white, foot pedal "bypasses" the unit so that after silent tuning they can easily switch it in/out the path. Well, we did a few quick tests, and that POS is horrible sounding. EVEN ON BYPASS. It really wreaks havoc with the sound of any acoustic instrument - searing electric guitars are less of an issue (:().

Anyway, I realize it would only impact your movie soundracks, but I'm interested with all that excellent gear if you've critically evaluated the impacts, if any, of those C/L's even being in the path...

UreiCollector
11-26-2008, 08:25 AM
I have not done an A/B with them......I havn't found them objectionable in use, so I'm running under the "what I don't know won't hurt me" mode of thinking. (This would be a great thing to test on one of those boring winter nights....and I may just do that.....or not....ha ha ha....)

Unfortunately, the bypass mode in this compressor is not a "hard" bypass....so I'm sure there are some negative impacts even when in bypass.....but for the price, I can't complain.

I would love to use a higher quality compressor....but between all of my hobbies / children / wife / mortgage....I have to make sacrifices. And given that I don't have to play "volume jockey" when watching movies with the wife....the impacts on the system are well worth it. It still sounds good to me.....and eveyone who has set foot in the room says it is the best they have ever heard.....good enough for me.

Here is a pic of the wall. As for rattles, no issues, never had any. I used a lot of nails, and a lot of screws.

Frederick,
Curious to know about the angle of the LR monitors. Are they aimed directly at the listening position? Sorry if I missed that point. Nice job on the soffit. Did you use neoprene around the Uries?

The angle is 15 degrees. I had to compromise on the toe in. When using the Urie's in free space, I found they imaged best if they "crossed" slightly in front of the listening position, however, it would not have been aesthetically pleasing, so I made sure that the front most seating positions in the room were covered within the ~90 degree beamwidth of the horns....as I've said, it was a compromise, but it has worked pretty well. In this room, they "cross" slightly behind the prime seating position.

As for spacing of the Urei's......i spaced them so that at the prime listening position, each L and R monitor was 30 degrees off of center.

Around the Urei's I made a frame from Poplar and painted it with DuraTex textured speaker cabinet paint. The frames are attached with "L" brackets directly to the cabinets....that way the 'reveal' from the trim to the front of the cabinets would remain constant.......then all i have to do is push the cabinet into the soffit, until the trim stops them.

Thank you for the comments!

I saved a lot of $ by doing most of the work myself.....I hired out the sheetrock (it's an art to do it right), and hired out the carpeting.....but I did everything else (design, framing, electrical, subfloor, insulation, etc).

She sheetrock is screwed to the framing....I don't know of anyone who uses nails with sheetrock.

Well unless you what to beat the crap out it with nails LOL yeah screwing it up is the correct way.

I would have thought cutting out the holes making sure its sized up and will fit in the correct space over the framing otherwise your stuffed if you had to do it again and plasterboard thou cheap as it is, will soon mount up in cost. Plus itís a messy thing with all the plasterboard dust.

The sheetrock installer hung the sheets partially, and then cut out around all electrical boxes with a 'rotozip' type tool......once the rock was fully secured, he then cut the openings in place with that same 'rotozip' tool.....quick, easy, and precise......no wasted rock.

He had all of the rock hung, muded, and sanded inside of 5 work days.

I do have grilles for all the Urei's (I had to make a pair for the 813's).....I havn't made any for the 2242's though....we are teaching my son to stay "on this side" of the coffee table. I may make some yet.

I went with the Da-Lite 'High Contrast Cinema-Perf' screen....it's remarkably transparent (acousticly).....

I noticed you are using a Sony 9000 preamp and the 9000 DVD player. I two have had these in my theater for 7-8 years. I have been wanting to replace them for a year or two now but can not find anything better or that is so easy for my wife to opperate. Do you use the internal crossover in the preamp to cut any of the lows from the speakers or are you running them all full range?

Ps. Stunning, is your screen a Stewart or a Draper???:):):)

I agree that it is hard to find something better than the Sony 9000 series. The 9000 DVD/SACD player is definately reference class in my opinion. Dad has moved on to the Sony STR DA4300ES (if memory serves correctly), and he is quite happy with it, however I just don't feel the need to upgrade....I'm just so happy with the 9000's. And some may call me crazy.....but isn't 5.1 enough?....especially when your using high end monitors, as opposed to [insert crappy consumer speaker here].

As for bass management.....I am not using the internal crossovers in the E9000, I do all of my bass management with the Outlaw ICBM, and some further processing of the subwoofer channels with the Behringer DCX2496.

The screen is a Da-Lite 'High Contrast Cinema Perf'. The price for this unit was steep enough....I wasn't willing to spend even more on the Stewart....and honestly, the quality of the Da-Lite is first rate.

The screen is 106" and the projector is a Panasonic PT-AE900U (720P 3-chip LCD), not the best of projectors, but for $1200 I can not complain with the performance......as I've said....compromises had to be made......I used the $ on the sound......

Projectors are consumables in every sense of the word and need to be replaced eventually. Nowadays that's sooner rather than later. Putting the $$ into the sound was the right thing to do, and it's an investment with lifetime potential.

I would say itís also cool to see it on this site!

Iím kinder wondering about the term now, home cinema/theatre. Itís a term that was mostly associated with sound back in the 1980ís when the first domestic Dolby surround decoder appeared on the market.

Why not, media room instead as it can handle all types.

Thou some old and new cinemas now with digital projection can also be on the same grounds as we they can play anything.

Well itís nice thou you got your living room home cinema in the magazine. Iím sure those who havenít passed by on this site will see it the Home Theatre magazine, and might take some notice of JBL!:)

Your theather are a huge influence for me, it's more or less the same as I'm planning/hopeing for over the summer but with Altec instead of Urei :bouncy:

One question I have, is it OK to have the front speakers that high or would it be better to have them lower? My frontspeakers will consist of 3xAltec A700 (horn and 15" basshorn) and I'm a bit conserned that the woofer will get to high if it's on top, so I'm considering that I maybe need to have the on the floor instead of like you?!

Hope it's OK, i used one of your picture to sketch a few solutions for my plans, here (http://avforum.no/forum/attachments/hvilket-utstyr-har-avforums-medlemmer/49728d1241600023-baldrick-sin-nye-hjemmekino-waf-hva-de-no-kino.jpg)'s one, and here (http://avforum.no/forum/attachments/hvilket-utstyr-har-avforums-medlemmer/49729d1241600028-baldrick-sin-nye-hjemmekino-waf-hva-de-no-kino2.jpg)'s an alternative so you maybe understand my question easier :)

I'm glad you like the room! Thanks!

The UREI's were designed to be mounted in the arrangement that I have here....typically in a recording studio the mixer would have been in the way. Another think to keep in mind is that my horns are mounted at ear level while seated...and since I'm using a coaxial driver, the woofer is also at ear level. The additional woofers in the cabinets are cut off at aproximately 100hz and shouldn't affect the pattern a whole lot.

Something to keep in mind with your plan is where the main "lobe" is at the crossover frequency between your bass-horns and your high-frequency horns...depending on driver displacement and crossover topology, you may have to have the horn located above the woofers. I personally think the 2nd image you sent would be the better setup (knowing nothing futher about above said issues). You may however be tight on space. You want to be sure that you have about 30 degrees off of center for your main left and right array, and putting the subs in-between may not allow that to happen (depending on your distance from the front wall).

Keep us up to date on your project...i love the idea of using large format horns in a home cinema like that!

There is just one other question thou. How loud is the LCD video projector or is it a DLP type?

I picked up my Hitachi CP-X430 yesterday afternoon and its flipping noisy on the fan at 55dbc at 4 feet way basically its got to go in the kitchen out of sight, its like leaf blower.:D

I noticed you’ve placed it high towards the ceiling and to the back slightly. Also the heat on mine whew damn and that’s the reason for the noisy fan sucking/venting out the heat.
