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

Mapman,

In Germany a chap called Matthias has been customising Ohm speakers for some years now and he does an active version of the "5000" series (with John’s approval). In Germany, this is a good idea because their Omnidirectional market is much stronger than anywhere else and the competition prices can take your breath away (German Physic, MBL etc).

Looks like John has fully embraced the idea and is scaling up. ;^)

Check out the Neat Audio Iota Plus speaker recently reviewed in Stereophile this month by staffer Ken Micallef. 

However, careful,...... John Atkinson, the magazine's technical guru was disappointed by their " measured performance", and Micallef's enthusiasm for the product is somewhat over the top.  The speaker should do 40Hz cleanly and without boom, according to him.  Good Luck locating a Neat Audio dealer where you can audition them.   

BTW, the speakers are a midget floor stander at 17 inches tall  (on their 1.5 inch spikes). Interesting product,  but not inexpensive
