Thanks.
Hey KC,

This is likely marketing jargon for frequency range. Yes, you can hear 35hz but how loud it will be in comparison to the upper freq's will depend on the design. Obviously, speakers w/ built-in subs like DefTech's BP towers will have a ton of energy in the lower octaves due to their built-in subs.

You bring up an interesting point tho and I'd like to add on to it. Can someone explain the difference between frequency response and frequency range? B&W posts both and I've always considered the freq. response to be the real world reference as it states the range +-3db whereas freq. range is the actual dynamic capabilities of the drivers before rolling off more than -6db's thereby rendering it inaudible. Am I wrong? Also, VSA quotes both anachoic and in-room freq. response. with in-room obviously having better low extension from wall reinforcement.

Isn't there some kind of standard out there?
