I just purchased a pair of these large horns that I plan on using on my Cornscala dbbs.I am running them 3-way with JBL 2445J drivers and a pro modified 511B horn cut for 2 inch driver and a APT 50 tweeter crossed at 600Hz and 10000Hz .After that being said has anyone used this horn and if so any info you can share on it.

JBL 2360 ,,,Why so big ??? 

Just bored I guess and looking for something to experiment with.

I am confused about what you are attempting. Are you planning to replace the Altec 511 with the JBL 2360 horn?

If so, the higher (and steeper) the crossover point on the JBL 2360 the better. These are CD horns (JBL bi-radial) with a vertical, narrow diffraction slot (required to get the CD dispersion). However at low frequencies, if a great deal of air is pushed through the slot, then it can distort to objectionable degree. So choose your crossover wisely. You will also need some CD equalization for this horn. The JBL driver is a good value. You can even run these as a two-way system.

Good luck,

The slot is approx. 7/8 x 7". I think for living room audio, you won't push enough air to get objectionable distortion. Maybe, but it makes me wonder. 

I have a pair that I got from JWC, but I have yet to get some 2" drivers. JWC and I thought some K69s would work well with these.

They aren't any more outrageous than some 402 horns...

Well, the proof is in the pudding.

When you have yours set up try the experiment. Use a high pass filter at 500 Hz and then change the filter to 750Hz. Then you can decide whether the distortion at the lower cutoff is objectionable or not.

BTW, I am not knocking the horn. It just takes some careful setup.

 They sounded ok with my motorola q9m as a driver.

Yes I am going to replace the 511B's and use those on top of some La scala bass bins I am building. I may use the dbbs in a commercial application down the road but for now I have them at my house.I haven't yet hooked them up maybe next week so I will see how they sound and take some readings.

I ordered a Behringer CX3400 crossover with constant directivity horn compensation so I will see how it works.

That is a good & flexible approach. If you can, the Behringer DCX is a more useful unit.

I thought I would start out with this one and if I don't like it I am only out $99. rather than $300.

I've been using the same unit in my system for a couple of years with great results. Sounds better than the DBX crossover that it replaced.

Don thanks for the input I am looking forward to using this as it is my first crossover of this type.

Hooked up one horn and these are fantastic sounding and I noticed no distortion crossed at 600hz
