Why is an XA30.5 a bad match for Revel Ultima Salon II speakers?


I actually own Revel M106 speakers right now, but some day, I intend to replace them with full range speakers like the Wilson Sophia II or Revel Salon II.

People say you need a lot of power to drive the Salons. The M106 and Salon II have almost the same sensitivity, and the XA30.5 can play the M106 louder than I prefer to listen (FYI I have a Velodyne powered sub). I guess my ears are pretty sensitive to loud volumes.

Does having all the mass of driving full range woofers into the 20hz range increase or complicate the workload on the amp significantly?

What is it about these speakers and many others that would demand a larger amp even at moderate volumes? My XA30.5 is supposed to be good for about 190W into 4 ohms, but nobody, including Pass Labs, seems to recommend an amp of that size for the Revel Salon II.

If I were to buy the Salons but had no amp budget, would I be better off trading for a more powerful but somewhat lesser quality amp than the XA30.5 such as a Parasound?

Thanks for the link, it was a nifty tool for discovering I needed to tighten up an air conditioning duct cover when my Salon 2s made it buzz at 20.1 Hz!
