OK, it makes more sense as you add some details. Meanwhile, I looked online, albeit half-heartedly, but I did not find anything significantly informative on these speakers, even at BD's site. Did I miss something? As you have seen, your proffered pics did not actually register here. I do like the sand idea; very worthwhile if heading down anywhere near 19 Hz. But now I am stuck thinking that if the DSP/LF amps curves are aimed at 19 Hz, and 19 Hz is limited to 88 dB, then an equalized output might also be limited to 88 dB before clipping and/or "unacceptable distortion" from the LF could "potentially" encroach; yet this makes no sense. OTOH, a sensible DSP could easily be programmed to simply throttle back or cut out at the lowest frequencies before distortion became audible. Have you actually run into clipping yet? Of course, there's not much in the way of recorded music that goes down so low; but no info has been given on the "roll-off" characteristics, hence the questions.
As for the DIY "F-M" curves, "tune-able" LF is the BOMB; beats the hell out of soldering up/rebuilding trial/error X/O's when integrating a speaker into a room.
