RE: At that frequency range

I disagree. Recorded music may not contain anything below 32 Hz except in rare cases, but low bass (below that) is present on many recordings in the form of venue information. An orchestra may not play a single note below 30 or 35 Hz, but the concert hall often conveys more.

One of my clients has electrostatic subwoofers that are flat to 20 Hz, I think 3 dB down at 14 Hz, with usable response to 8 Hz. Another client is considering a pair of Bruce Thigpen's unique rotary subwoofers (http://www.rotarywoofer.com) which are effectively flat to DC. Thigpen's product rolls off substantially above 30 Hz. That is a subwoofer, and for its performance is something of a bargain, in my opinion.
