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


Also what bass driver or drivers do they use?

Thanks.

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?

The lowest frequencies produced by almost all musical instruments are not as low as commonly believed. For instance, whilst 28Hz was above stated as being produced by an upright bass, that instrument's lowest note---the E string played "open", is actually located at 42Hz. The 4-string electric bass (often incorrectly called a bass guitar, even by John Atkinson, who should know better) produces that same note and frequency as it's lowest.

There are a few instruments which produce frequencies lower than 42Hz, including pipe organ, grand piano, and contra bassoon. Some recordings made in very large spaces---cathedrals, concert halls---contain the very low frequencies those rooms support. The ability to reproduce those very low frequency "room sounds" is one of the benefits of good subwoofers. A good recording of a pipe organ played in a cathedral will contain the "shuddering" sound that combination produces. It is an enormous, massive, thrilling sound!
