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

Also what bass driver or drivers do they use?

Thanks.

Zu Definitions go flat to 16Hz. They have a 12"x12" footprint. But they are also 50" tall. AudioNote ANE has bass down to 16Hz, but I think that there is a roll-off; and they use corners to reinforce the bass.
