Gonk, I have now looked at the press releases you cite, and I am really confused: the LFM-1 Compact joins the LFM-1 and LFM-2 at showing a frequency response of 25Hz - 180Hz +/- 2dB. That is, all 3 subwoofers, though differing in size and cost, have exactly the same specs! What am I missing? Or is this another "cut/paste typo"?
