Jack, The Maestro had a lot of the same characteristics of the EP-600. They both (as does the Velodyne DD-18) have the ability to react more quickly than does the SVS pair - and yes, the SVS pair means two 12 inch drivers in two big cabinets.

One area which actually helps the Axiom is the designers made what I consider to be intelligent choices. The Axiom is ALWAYS in the same tune, with the amplifier optimized to match. This tuning gives bass down to about 16 Hz in our large room. The SVS, quite frankly, can go even lower.

But, 99.99% of all bass is 16 Hz and up, and the EP-600, right now, is walking away from the SVS PAIR in real world performance.

Later this fall/winter, when I get a new Hsu VTF-3 HO, I will be trying all three nearfield, for confirmation.
