1.5 inch compression drivers for JBL 2384

[AdamFelix]

I have just put in an order for two JBL 2384 waveguides. There’s probably not a lot of experience with alternative drivers for this waveguide as there is not a lot of horns or waveguides out there with 1.5 inch throats. But regardless I would appreciate any thoughts on the subject. What should I look for? Are the other brands superior to JBL? As I can see, BMS, B&C and Eighteen Sound makes some suitable drivers. Have I missed someone? Thinking of crossing active at around 600 hz to either forward firing woofers or making it a synergy like the syntrip by weltersys.

eek, that is a bit lower than I'd recommend crossing, especially if you blast the volume and even more especially if not using 24db active crossover.

Superior ?

Maybe Tad, but they aren't all that different from jbl.
Beryllium diaphrams sounds nice.

The original screen array system crosses at 630Hz (active) or 800Hz (passive). Is it possible to use a 1.4" compression driver? the dimensional error is small. BMS coax are available with 1.5" throat but very expensive...

I use 2384 on top of the JBL 4722's with a steep active XO at JBL's recommended XO of 630 Hz. Based on user notnyt at AVSForum tested a few JBL 1.5" CD's on 2384: Just purchased a pair of JBL 4722n speakers. - Page 129 - AVS Forum | Home Theater Discussions And Reviews

Preferences are:

1) 2452H-SL + BeX4008
2) 2452H-SL / 2453H-SL
3) D2430K
4) 2432H

I switched out the stock 2432H 3" CD driver with the the 4" Aquaplased 2453h-SL as per notnyt's findings. It is the best bang for the buck. Smooth sounding with low distortion. The downside is that you can't just drop in different diaphragms, but the price is right compared to the other JBL drivers... Post's 120 thru 140 have all of the driver measurements on the thread.

The 2384 and 2453H-SL is a combination i've wanted to try for a while now

Hi AdamFelix,

If you can afford it, I would get the JBL 2435HPL with Be diaphragms. They can typically be had second-hand on Ebay for a lot less than second-hand TADs. I have not heard them myself, but djk (RIP) used to like the JBL 2384/2435HPL combo very much, and he knew it all.

Best regards
Peter

2nd the 2435hpl.
Djk listened to it on the 2384 horn.

Even new at $1,100, they are a deal.

What I can gather from the replies so far is that I shouldn’t go for other brands than JBL.
No love for B&C or 18sound?

I have been looking at these:
DE1080TN - B&C Speakers
ND4015BE - Eighteen Sound - Professional loudspeakers
ND4015Ti2 - Eighteen Sound - Professional loudspeakers
NSD4015N- Eighteen Sound - Professional loudspeakers

If you can afford it, go with a 4" Beryllium diaphragm and forget the rest. That leaves you with the Radian 950PB-Be, 18 Sound ND4015BE, and various JBL. They will all perform similarly.

 

[ErnieM]

Then you have the coaxial compression drivers.

BMS 4595HE
B&C DCX494

More complicated to get the crossovers right, but will provide more clean output down low if needed. Not really an issue in most home environments.
