What are the smallest speakers that are clean and flat down to 20hz?

I'll need to find a way to download that Phil Collins track as a WAV or MP3 to test since I'm using digital room correction. Might be able to get the audio from Youtube to stream over DLNA as well, but I have not looked into it.

In my case, the loudspeakers are close to the walls (18.5" away on-center) for soundstage reasons more than for bass...which I have too much of in this room without correction.

Is there a small, inexpensive car that goes zero to sixty in under 2.5 seconds? And I also want it to handle like a Porsche and hit a top speed of 250 mph. And have a full size trunk with the ability to drive underwater and get great gas mileage…for under 1200 bucks...

Check out Neat Motive SX1, a petite floor stander that extends down to 25Hz. http://www.neat.co.uk/p_pages/motiveone.php
A great musical speaker that punches well above its price point

Ct I hear most of the indicated bass notes that were added there. Level I hear is down some at 30 hz and harder to discern lower. That is consistent with fletcher Munson. This was with moderate loud volume on my main system Using an older Pc usb feed to mhdt Constantine dac to arc sp 16 pre-amp to Bel Canto ref1000m amps to Ohm F5 series 3 speakers (12 inch Walsh style driver with on board tone level adjustments to room size).

Room size is ~ 22x34 L shape with normal to slightly lower than normal ceiling height and 3 openings to adjacent rooms. I coukd try again with the doors closed as I usually do to max out low bass.

That at was very cool with the visual display. Thanks.

Wolf probably not but who would not want to know which actually can do it all best and for how much?
