- So far, I demonstrated how the Buchardt DSP work with low end extension, and that according to the manufacturer's data. I
verified the claimed
"25Hz" in-room, as I also verified that past 90dB/1M, the low end
will collapse, whatever you want to believe.
And that applies to the A700 as well: Why? Because
SB Acoustics 6" paper cone drivers cannot handle 17Hz at 90dB+/1M. Not with A500, nor with A700. Using five of them in a bigger enclosure won't do that much better either... The limitation there will be amplification before the drivers excursion: You got three more drivers to feed with the exact same power. How that may be a thing? I sure may be proved wrong, but I need data to do so. I want to see this "
17Hz at 93dB". Until then, I don't believe it. Period.
