...The most obvious problem is with the Bass drivers, which are left to radiate both to the front (via the horns) as well as to the rear... which in this case really means to the front!... The rear of the drivers are aimed upward at a 45° angle where the sound would bounce off the ceiling, then continue at 45° right down to the listening point, arriving I would guess somewhat late to the party. This is not something that can be fixed with a DSP (the output from the rear of the cone being physically linked to what comes off the front of the cone).
….. Too keep for this horn (it is aluminum-made) without back chamber is so funny that … it become even not funny. The only way to make 60Hz horn so short is open up the throat to full throttle, most likely the full 15” as the size of that 515G driver. If this guy has such a large throat then this horn has very little gain. Let presume that it does +3dB at its lover at its lover knee. Then, (with the back chamber wide opened and positioned where it is) the guy has upperbass MF arrays of two sources, with 3dB between them, reserved polarity and with time discrepancy that could not be addressed at digital domain. |
