Jbl Array.

[Brian DK]

I am wondering why the Array Series have vertical horns, when all the big
brothers like K2 and Everest have horizontal horns.?
Is there an anvantage on vertical, and then why is the the bigbrothers then vertical.??:confused::confused:

[Maron Horonzakz]

The verticle position is because that horn is a diffraction design and has a wider despersion pattern that way,,,its like the earley electro voice t-35 tweeter,,

[Valentin]

The larger systems would have looked pretty goofy with vertical horns.

The nice thing is that, if you really prefer function over form, you can place a pair of SAM1HF's over something like an Everest II bottom end.

Seriously. It works.


Indeed

Because the Array is for HT,and vertical horns can avoid shade screen:D

[cooky1257]

According to G.T., you can't have anything on either side of the horn. It has to be freestanding, regardless of the fact that it is a 90x60 horn.

Oh bummer, I'd planned to mount mine in enclosures like thishttp://farm9.staticflickr.com/8253/8609670600_20c3220d59.jpg but with the 2206 mounted lower and a deeper chamfer from top to 2206 to accommodate the SAM1....

[4313B]

Just do it anyway.

Sorry, But what is HT? :dont-know:

Home Theater, probably.

I wondered about this as well. Correct me if Im wrong, but In Jbls history the only driver that used diffraction in the horizontal plane is the 077/2405. And as far as I know this tweeter is well regarded in these parts. It would be interesting to turn the 2397 90oand try it out. Anyone with experience of that?

[bubbleboy76]

I once suggested to the owner of a pair of 4365 to put them on the sides, and try vertical horns. He just laughed :)

The Smith Horn?? The directivity is all wrong for that look at the polars especially the vertical ones.

[Mostlydiy]

I just figured diffraction in the horisontal plane would be intreresting to try out. Not many horns work that way, and suddenly the 1400 array turned up utilizing this feature. The horn designs of course is rather different. Well, It will be fun to try out. I will probably have a couple of 2397 incoming as well :)

Wow, I love this design. Inspired by Avalon?

Which driver is it for the LF?

[cooky1257]

Actually inspired by Giskard's(4313B) use of the 2206h, SAM1 HF.
The cab is a modified Wilmslow Audio Prestige kit (but yeah I think that was Avalon inspired).
Only good down to 55hz so am intending to use a(maybe 2) BK XXLS400 sub to handle the first 1 1/2 octaves.

[Mr. Widget]

Have you given them a listen yet? I always test and retest before spending hours finishing a design... Looks very nice, I've been planning something similar for a while now... just not sure how to integrate that horn. I want to maintain the sonics of the 1400 Array, but avoid the "goofy" looks.


Widget

[4313B]

It looks quite interesting!

I'm curious as to how you will like the 2206H with that horn. I think it works great and you have to like that 96 dB, W, m. G.T. might just be right, the 4-inch voice coil makes all the difference.

JBL does use the 2206H in the 2.0 cu ft box tuned to 40 Hz which yields a bit more bottom end.

I ended up with a 1.2 cu ft box tuned to 60 Hz to tighten up the bandwidth a bit given that they were intended to use with subs. Mine are just boring rectangular boxes. :D

So... SAM2LF? Or the readily available 2206H or its neo equivalent beneath a SAM1HF?

Finally completed the construction/finishing

Fun with XTA DSP to follow, will drive them with 2 Linn LK100 power amps.

[moparfan]

Great job! I really like how they look.

[wsilva]

Oh that is sweet!
What a great looking custom design, some hard work must have gone into those:cheers:

[4313B]

Can you please make me a pair too? :D

[cooky1257]

Thanks for the kind words. Some first impressions after a few hours using settings for the SAM1 already in the XTA memory and some quick n dirty tweaking for the 2206 (so far 12db/oct bessel @552hz) wow! Transients, rim shots to die for, mid detail and floor toms, oh the toms..really pleased thus far, can't wait to see /hear the sub fill out the bottom end.
I was a little worried the enclosure may spoil the good imaging but nothing I hear makes me think it's any way inferior to the stand alone SAM1.

Thanks for the inspiration everyone.

[DavidF]

Very nice work. I like the way you integrated the horn into a "box" enclosure. Overall has a nice finished look.

Great,you are talent,even better than original JBL ARRAY 1400:applaud:

[Mr. Widget]

Great,you are talent,even better than original JBL ARRAY 1400:applaud:I agree... very nicely done. I'd like to see one done in all real wood veneer, but that would be a real pain.

I first thought of this pairing of drivers a couple of years ago... have the parts, but that is as far as I've gotten. In my plans, there is a Sub1500 tucked away in the design as the 2206 is really only a midbass driver. A punchy and exciting one to be sure, but asking it to go below 60Hz is a stretch.

So Cooky, since you are years ahead of me... please keep the comments flowing. I wish I could hear your magnificent creations.


Widget

[cooky1257]

Thanks for the feedback.

They definitely need a sub(one 1500) or 2 of the BK/peerless subs BK XXLS-400 Subwoofer Review | AVForums.com - UK Online (http://www.avforums.com/reviews/BK-XXLS-400-Subwoofer-Review.html)
I've got just the one at the minute but now think 2 would be twice as good!
Of note is the 2206h's I have are NOS and have broken in/loosened up quite a bit from yesterday.
Go for it Mr Widget.

[Robh3606]

Hello Cooky

They came out really nice. You are doing the SAM crossover for more sensitivity?? So do they sound as kickass as they look?? Do you like them better than the 2235 based pair you had?? I would think on the right material they can sound really fast and effortless.

Rob:)

[cooky1257]

They're fully active Rob. They sound 'fast' yes-it's the best way to sum them up. Cleaner, faster than the 2235 and the Precision Devices versions.

[cooky1257]

After lots of listening and playing about may finally settle on 2nd order Butterworth slopes @800hz(600/1048hz) with 110mm delay on bass driver.
Need to get some measurements done but my ears are saying smooth integrated sound with best imaging..

The Reason for vert. mtg. the horn is to mimick the Concert Stacks (coverage pattern) hence "Array"

This was a really great project .

Do you still have these ?

( If so ), do they outperform ( imaging wise ) your other K9800 project ?

cheers <> :)

[johnlcnm]

Used 2206s as a replacement for the 2214s in a pair of 4425s. Split the passive crossover into separates. Disconnected one end of the LF inductor on the existing xover. Used a "sub-Bessel" second order with an Erse iron core low resistance inductor for the 2206s. Holy crap! What a difference in these speakers. Yep. Snappy base drums and rimshots, not to mention a really good midrange, much improved over stock boxes. Bumped these little monitors to the next league. Left the cabinet tuning the same, approx. 40 Hz. Need to do a little write up with some photos. 2206s are a serious upgrade to the 2214s that were stock. I can't believe how easy this was.

Regards,

John

Oh, and by the way Cooky, really snazzy looking cabinets! I feel a want for those! Really cool.

Yes I still use them everyday. They present a considerably smaller but sharper/more pinpoint and deeper stereo image than the larger K2 types.
By smaller I mean individual components within the soundstage are sonically 'smaller' unlike the somewhat larger-than-life delivery of the K2 presentation.
I did play with rotating the H9800 horns and the imaging did become more focused by I lost something too-they oddly became less satisfying somehow(lord knows why) so they stay as they are. Thanks for the nice compliments guys.

Thanks for those observations!

They are quite intriguing .

Without being able to reference them to some polar plots, one is left to muse as to their involvement to listener "satisfaction" .

Maybe the 90x60 nominal coverage of the 4338 horn ( as mentioned by 4313B ) versus the 90x40 coverage of the H9800 ( both on end of course ) played a role in your level of satisfaction .
- The 60x90 would of course have more room involvement ( giving a more spacious sound-stage ) .

cheers <> :)

PS ; I would love to see some polar plots of the H4338 ( or an actual Array horn for that matter ) / I don't think anyone has ever published them. Anyone ??

Cooky
in another thread I was asking about the advisability of mounting a 1400 Array horn in an OB (for aesthetic reasons) and someone pointed me to this thread. That’s a great implementation. Can I ask how you mounted / fixed the horns in place?
