In pursuit of pure playback realism and a system that has low compromise in in-the-room tone and presence I will document my mistakes here in this thread. The goal of the horn array is to have no hesitation in believe ability when listening to a good recording. I find from the upper bass up must be front horn loaded, otherwise it just sounds like a speaker trying to be real paddling away at the room air sounding fake. Horns move the air needed for the human to be fooled into experiencing realism. The system is made to fire down the long walls of my rectangular concrete bunker and sits on carpeted concrete slab. The system is made to work with the room.
Here is the in room response of the low midrange and upper bass (heart of the system), one channel 15' away at the listening position. Here is where most of the music lives and this compact horn system is built around this range first. This range consists of two parts, one the B&C 8pe21 in a 46" long front horn with an 8 square foot mouth and 4" throat 120 - 1K range @ 106 db/w/m sensitivity. Two, the horizontal floor coupled line array stands for the midrange horn with four sealed 8" woofers wired in parallel with 103 db w/m voltage sensitivity. These two parts are biamped and the upper bass coupling stands operate 60 to 120 cycles and can be precisely aligned with the 8pe21. If you get this range right you will have a basis for a system with realistic in room sound. The bass modules are high passed 4th order at 60 cycles and operate in stereo. The midrange horns can operate up to 800 cycles realistically.
