Jbl d130 + le175+1217-1290.

[Doc Mark]

Greetings, JBL Friends,

I have a band reunion coming up in early October, and I'd like to update one of the old vocal monitors that I used to use "back in the day", when I played professionally. I have several monitor cabinets, of various internal volumes, that could be used, most of them cut to fit a single 12" JBL (K120 or 2130). One larger one is cut for a 15" speaker, and a horn, and I've been thinking about putting something together for that larger cabinet. As you can see in the title, I have a single D130, and also an LE175 compression driver, a JBL LX10 crossover, and a 1217-1290 "potato masher" horn/lens combo. Seems to me that this setup should work well, even though the LX10 is really meant to be used with an LE14A. I was thinking, if the D130 would fit into the larger cabinet, I could run it full range, and then use the LX10 and horn/lens combo for the frequencies about 1,500 HZ.

What do you think about my plans? Will they work out OK? Or, should I use a 12" JBL in place of the "15"? I can take and post photos of the various combos I can use, cabinet-wise, if that would help you. I look forward to your comments and suggestions, and thank you in advance for sharing such with me.

This band reunion has blossomed into around 110 people, from various bands that all played in the San Diego nightclubs in the 1970's and 1980's period. We'll have lots of horns, several outstanding rhythm sections, and lots of singers. I'll be singing lead vocals for a half dozen songs, and also playing my congas and other Latin percussion. I'm really excited about this, even though I've not done any modern music for many, many years. Thanks, again, for your thoughts on my monitor update, and God Bless!

Every Good Wish,
Doc

Hey Doc - could you beg borrow or steal an active crossover? It would sound a lot better than trying to cobble crossovers in such short notice. As you know, the D130 and LE14A are opposite speaker types so you really gotta get the correct crossover to have a chance. At best, those old crossovers were no rose. I think you need a N1200 / 3120 for the D130 + 175. Sounds like fun! I still play a bit but my chops are non existent at this point! We had a giant Kenton blow-out here in Detroit a few months ago and brought in guys from all over the planet in order to cut the stuff - including John Harner who still has serious chops! Mike

Hey, Mannermusic,

Many thanks for your thoughts on my monitor update. Yesterday, I dug out the larger monitor cabinet and saw that it was cut for a 12" JBL speaker, and not the 15" that I thought I remembered. Plenty of room in the box for any of several horn/driver combinations, too, but the box has been ported (rectangular port). I'll have to run the formulas for my K120's, or 2130's, and see if the porting will work. I used to use them in sealed boxes. As to crossover, I do have a couple that would work, including an old Crown VFX-2A, and a much newer Ashly XR1001 (USA-made). I could run either with an older Crown CD300A, or a smaller amp, and that should work. I could use a D150, instead, using one half for the lows and one half for the highs. I seem to recall that amps might not like being split like that, but for the short time I'd be singing, it shouldn't be a problem, I'm thinking.

We'll see how it turns out, and much depends on how much time I can get, in order to modify the cab I choose. If I had a 2402H, I could use one of the 12" transducers and the tweet, in a smaller cabinet. But, as I don't have one of those, that is a mute point. Thanks, again, for your thoughts, and suggestions. Much appreciated. I'll see what sounds good, and go from there. When the gig is over, I'll post a few photos here, with a report on how the monitor worked for me. Thanks, again, and God Bless!

Every Good Wish,
Doc

Doc,

How 'bout a 2404 with the baby cheek radiator? If I remember right, that was the HF basis of many a 2-way portable rig. I got 'em, if you want 'em. ;)

Hey, Greg,

Thanks for the kind offer! What are you asking for one, if I may inquire? Does it have a proper JBL diaphragm in it? Thanks, again, for the offer, and I'll talk to you soon. Take care, and God Bless!

Every Good Wish,
Doc

P.S. I wonder about encountering feedback problems with the 100°x100° coverage of that horn, compared to the 40° conical dispersion of the 2402H?

If by 'proper', you mean original, then I believe "Yes." is your answer. I certainly don't need compensation of any sort. I will just pick out a pair, make sure they 'ohm out' OK, and FedEx em to you. Interested?

Greg

[cgregory4]

Doc,

I cannot speak to the 'feedback' question. Every single person on this forum is smarter than I. Again, my only knowledge comes from seeing a bunch of these critters 'pardnered' with 12" JBLs for road rigs.

Greg

[Doc Mark]

Greg,

That is a very generous offer, and one that I cannot refuse. Thank you, very much!! I'll send you my contact info in a Private Message, and we can further discuss all this. Thank you, again, and I'll talk to you soon! God Bless!

Doc,

Certainly, and my pleasure! I'll FedEx them tomorrow to you and PM the tracking info!

Greg

PS -- I have a couple 2202s I'll send, as well, if you want to try different 12"ers.

[Doc Mark]

Evening, Greg,

You are TOO generous, my friend!! Did you give my question about working up a trade, any thought? The 2202's are tempting, but I was thinking that they were more setup for systems like the 4350, isn't that right? It seems that the K120, or 2130 would be better in a vocal monitor, as they offer a clean, bright, extended mid-range. For that reason, I would think they would be much better for this application. However, if we can work up a trade, it might be fun to try the 2202's in another sort of system. Please let me know if you are seeking anything, or I can send you a list of goodies I have that I can send you in return for the goodies that you have so kindly offered me. Let me know if there is something I might have, and I'll check my stuff, and see what I can send your way. Thank you, again, for your kindness, and I look forward to talking to you further about the possibilities. Take care, and God Bless!

Every Good Wish,
Doc

[cgregory4]

Doc,

I have been unusually blessed. I should 'pass it on' given my time is short. I just saw the 2202Hs stacked in the garage and haven't a clue whether, or not, they are helpful re your reunion. Just know it would be my pleasure to assist.

Greg

[Doc Mark]

Greg,

I'm going to respond to your comments in a PM. Talk soon, and God Bless!

Doc

Hello Doc,

Sorry for the late response. Please check your messages.

The 2202Hs: I seem to remember they are the same sort of driver, ie. combined with a tweeter in a 2-way and used in many a gig. :) Of course, I might also be totally wrong.

Others might want to comment on the 2404/2202H combo. Anyone who does comment will certainly know more than I.

Greg

[Doc Mark]

Evening, Greg,

I'm so glad to hear from you, and very much appreciate your message in the PM section! I've replied just now, and will talk to you soon. Got to get back to work right now. Talk soon, and God Bless!

Every Good Wish,
Mark

[cgregory4]

Doc,

Still waiting on someone smarter than me to jump in. (That would be any other soul on the LH site! Ha!) In the meantime, I'll show my ignorance. :o:

The 2202Hs have a good frequency response: 60 Hz to 4 kHz.

The human voice is roughly 65 Hz to 1280 Hz (Although a 'high-soprano' scream can hit 3 kHz. :) )

The 2404s are very close to the 2402s you were initially proposing, and will reproduce the human voice harmonics.

http://www.jblpro.com/pages/components/uhf_drvs.htm

Mannermusic's suggestion of an active crossover, and your response about your Ashly XR1001, seems a simple xover solution. (Should be fun to play with!)

As far as the feedback issues go, I've admited my ignorance. However, my favourite lightweight JBL monitor -- the 4425 -- has both similar drivers, with the tweeter offset above the woofer, and both in the same enclosure.

Regards,

Greg

Hi, Greg

I'll be calling you when I get back up on the mountain. Finished at the Dentist, and now have to drive down and send some work stuff out at UPS. Should be back in the mid to late afternoon, and will give you a shout, then!! I like your idea, and in fact, may turn my largest monitor into a 3-way system! It will be the best it's ever been before, and my aging voice will most certainly appreciate it when I can hear myself singing, despite the huge horn section that's going to be there!! Many, many thanks, my friend, and I'll talk to you soon. Take care, and God Bless!

Every Good Wish,
Mark

Evening, Greg,

I very much enjoyed our talk this afternoon, and look forward to more in the future!! I'll be contacting you this weekend, or early next week, when everything plays out as it should. Thank you for sharing a bit of your self with me, and I look forward to talking again, soon. Take care, and God Bless you and yours, always!

Photos, as soon as you have them, and, hopefully, before the San Diego reunion! :)

Greg

[Doc Mark]

Hey, Greg,

You bet!! I will take before and after photos, as the monitor takes the form I think will work like a champ. I'll also take some photos at the event, of me using it!! Thanks, again, and talk to you soon!! BTW, I sent you a PM with the medical stuff I take, and hope it works for you, too! Take are, and God Bless!

Every Good Wish,

Morning, Greg, and All,

FedEx dropped off three boxes here, yesterday! A bit on the heavy side, each box was packed better than any other I have ever seen!!! EXCELLENT job, Greg!!! I was working at the their time of arrival, and so had to wait a few hours before being able to unpack the works, see Greg's fantastic packing job, and inventory the contents. Here is what I received, thanks for the kind generosity of Greg!

67332

67333

Included were (2) 2202H 12" woofers; and (4) 2404H Baby Butt tweets!!

67334

The 2202H drops right into this particular monitor, which is the one I'd hoped to finish and use at our upcoming band reunion. However, I had forgotten that the 12" will need some JBL MA15 clamps to hold it in place, and I will also have to do some work to fit in a 2404H.

67335

Unfortunately, time is very short, and our business work demands are, as always, pressing. So, I'm not sure how all this will turn out. But, I'm excited about the possibilities!! One other cabinet I have will hold both 2202H's, and one 2404H, but it's not actually a vocal monitor. Still, that might work if I lean it back into the proper position. I also have smaller monitor boxes that may offer more choices, but still need to dig those out of the Hobbit Hole (our basement).

One other problem is that I don't have proper crossovers for these drivers. But, I do have plenty of amps, and several electronic crossovers, so that can be obviated, if necessary.

I want to offer heartfelt thanks for Greg, for his kindness and generosity, and I look forward to "paying it forward" in order to square this deal!!! Greg, I'll keep you posted as to how this all turns out, in the short term, and also in the long term. After the band reunion, I'll have time to work up quite a few combinations of these components, including the 3-way that I mentioned, adding in the LE175 with the potato masher horn/lens. From one Texan, to another, many thanks, and may God Bless you and yours, Greg, always!! Talk to you soon on the phone.

Every Good Wish,
Doc
