I do look forward to your comments on the Yorkvilles once they're dialled in though. Should be an interesting comparison.
Haven't sold anything . I'll post impressions once I'm dialed in.

Ah well, that's simple then Greg. JBL's up front and Yorkvilles as surrounds...

What crossovers are used for the JBL? Sometimes a better crossover will be better than all the parts IF not done properly.

Passive crossover from JBL between the mids and tweet. Active for the bottoms (dbx xover). I agree about a better crossover implementation resulting in better sound. I was mainly just interested in a change up for the sake of simplicity. If I took a significant hit in sound quality then I just go back.

I just did the same thing, I am not even using any EQ right now and the results are much better than expected. I really would love to try a DR-200 with dual compression drivers as the BFM designed speakers were the most dynamic I have owned. I just don't want to mess with EQ anymore and if someone can really build a proper crossover with good off axis I bet they would be my favorite.

As a previous Yorkville U215 owner I can say that I was not crazy about their off axis performance. The sweet spot was fairly narrow in my room but boy did they have some nice midbass to them.

Agreed, I had them with 5.5 feet in between L&R and that felt pinched. Then moved out to 8.75 and now gonna be at 7.25. We'll see if that provides enough separation without compromising the sweet spot.

Angle any speaker to create the proper sound stage. Some need more toe in than others.

For me it was a dispersion pattern issue (off axis response) for mainly the center channel in an HT setting. The center channel tonal characterics with the Yorkvilles changed quickly. By the time I moved off axis by just 5 or 6 feet by the listening positioning (basically moving chair to chair in my room) the sweet spot was long gone. The JTRs I had and JBLs I currently own were much better from this standpoint.

The dreaded center channel! For a speaker like that it has to be farther away to let the pattern hit a larger area.

This is what is limiting my center channel options in my ht room. I was wanting to do a JBL-3732 clone with duel 2226's for the low end, but, in reality as John pointed out to me, with my room being only 13ft & 3" deep, I really do not have enough space for the drivers to sum properly.

3" deep room is pretty small. Might only have room for a pillow instead.

Ya know, I'm diggin em. Just on paper both have capable midbass and mid-range no doubt about that. I will say the high end on the yorkville is a l little more relaxed sounding. Not rolled off but smooth. Now... The thing that surprised me was the midbass. I put on Metallica through the never and the drums were the best I've heard in my room. Could be the efficiency in that area because I actually had to pull down the midbass as it had a peak. Could also be the physical orientation of the drivers. Either way I like it.

For all things related to the screen in play (movies and concert blu rays) I've got nothing to complain about. I do have some tweaking to get the center channel up to its full potential as I've heard it better before. The 60 degree dispersion of the center is actually not the problem I thought it would be. I will say that when I've had the 3731 set up the most ideal, two channel music was a notch up over Yorkville, they sounded more live. But with concert blu rays actually recorded live, the Yorkville sound...Lively.

Can anyone tell me the model of the high frequency horn and the mid horn used in the JBL 3732? Any good ideas on where someone might locate them for sale?

I would suggest trying to get them directly from JBL. You might be able to find the 2384 horn which is the top on eBay but if not my buddy ordered a couple those from JBL for very reasonable.

It's been quiet on the set. I bought a project car so now my time has been shifted to that. I'll be back in the mix soon. Can't stay away too long .

So the 2384 is the high frequency horn? I wasn't able to get your link to work. I have googled and searched all over me can't find any info on the horns for the life of me.

Just Google 3732 MHF technical manual. The manual has all the part numbers for the various components in an exploded view of the speaker (or in this case the MHF unit).

Can also get directly from JBL pro website, it is under service tab, exploded view, cinema/theater.

Last time I checked the 3731, 3732, and 4722 share the same CD and horn.

Yes, the 3731 and 3732 uses the 1.5" JBL 2432 on a 2384 horn for the high frequencies, then a JBL 165H mid range driver on a horn that I am not aware of its model. I believe that the 4722 uses the same one.

I wonder how the 1.5" JBL 2447 performs versus the 1.5" JBL-2432 that is used in the 3732, 3731 and 4722 on the 2384 horn?

Let's say that I do decide to build a quasi clone of the 3732, with a properly designed, custom crossover, not the stock unit. Which would be the better performing compression driver, the 1.5" JBL 2447 or the 1.5" JBL-2432?

Do you own some 2447 CD's already?

It's probably a lot easier to go 2 way - like a 4722(N) than muck around cloning a 3 way. I know MKtheater did a clone of the 3732 on which he used a different LF section. But if I recall correctly, I think his M/H-F section used standard 3732 parts.

MK will correct me if I'm wrong.

IMHO I prefer the 2447 on the 2352 horn than the 4722 top section. The 4722 gets you 2hz extension on top from 16khz to 18khz but the 2447 and 2352 digs deeper and has a more robust vocal section to me. I did not even use a proper crossover either. I crossed at 500hz with the 2447 to my 2035 bottom section sealed. My clone was of the 3731 and instead of the 2226 bottom I used the woofer in the 3722.

To me the key to this is a good crossover. Owning the Behringer speakers has taught me simple is better. The JBL 2447 and 2352 with the 2035 bottom is one wicked speaker but for me to use it I would need someone to build me a proper passive crossover or otherwise the Berries are preferred. Who here can do that? Proper I mean on and off axis.

Yeah, there's a LOT of sauce that's goes into a good crossover. I wouldn't contemplate using anything but the proper JBL passive XO between the M/F and H/F horn sections on the 3731 and 3732.

The XO's for the L/F section to M/F horn on those particular screen arrays are all active so you don't get to make that choice. But JBL pretty much gives you the info on where that should be anyway....or at least a good starting point if you are rolling your own L/F cabinet like you did (and Greg has done here).

My only problem with active DSP is getting the noise floor low enough in a small room. The passive crossovers make my room super quiet with less in the signal chain to raise it.
