Contemplating a new build. I miss my horn setup I had a number of years ago. I have been looking at some options and stumbled on the HLA4895.
The HLA4895 is a three-way setup consisting of the following components:
14" LF unit 2254J (which can run from 120-297Hz). It can be run lower when used in a LF-reinforced array (like when 6 of the 4895s are stacked together), but maybe in a home listening environment this can be extended down a bit with DSP and EQ.
10" MF unit 2251J 297Hz - 1.14 kHz.
4" HF unit 2451SL 1.14 kHz - 18 kHz.
The interesting thing about these is that they can seemingly be removed from their exoskeleton to reduce most of the bulk. Make no mistake, it's still a big horn, but might be more manageable.
For 20-120Hz, I'd need to design something else. Likely a sealed direct radiating stereo pair. I haven't got that far yet.
The system is going to need to be 4-way active with 4 amps and a crossover. Fortunately, JBL also makes a XO unit (DSC280) that can also be found on the used market. These have the filters for the LF, MF and HF components of the HLA4895. They have gain recommendations for a number of tour amps, but I'd want to use perhaps a 8-channel ATI amplifier or two 4-channel amplifiers (2 channels bridged for the LF unit and separate sub amps).
Just doing some thought-experiments here.
There is actually next to no information about these other than JBL's white papers and setup guides, but here is a picture of the array outside it's rigging skeleton:

I think it could make a pretty nice system, especially if I can find a pair that are from a rental company or something. I'm trying to get the actual measurements of the array. The good thing is that it can be field-disassembled (presumably to allow touring outfits to replace drives, troubleshoot etc.).
