I've experimented quite a bit with amplification of Salon 2s nd found that bi-amplification of these speakers to be absolutely essential. The problem is that while you can power the salon 2 with hefty Mark Levinson, Boulder, Krell, Pass Labs or any other high quality high power amps (in my case MBL-9007 dual mono amps 400watts/8 ohms), the back EMF caused by powering three 8 inch aluminum cone bass drivers below the 150hz crossover point to the amplifier is polluting the three high pass drivers. The high pass drivers which consist of 1" beryllium tweeter, 4" inverted titanium cone mid driver and 6.5 inch inverted titanium cone mid bass driver really don't need much power. In my case I had the best results with Nelson Pass First Watt J2 30 watts Class A amplifier to power this high pass section. I dedicated the MBL-9007s just for the three 8 inch bass. The difference in this configuration is night and day. Salon 2s just came to life. Interestingly enough when I measured the frequency response characteristics of the low pass section of the three 8 inch drivers there is a cliff like steep low pass cut off slope at 150hz. Can you imagine the amount of passive components ala inductors and capacitors that gets in the way of music to achieve this. By the way, no matter what amplifiers I used powering the low pass section driving the three 8 inch aluminum bass drivers, althought the frequency response curve truly confirm an amazing deep linear bass response down to 20hz, I feel as though the bass transient speed and amount of air it moves to recreate a true symphonic event is not quite there. I think Revel could have used larger diameter lighter mass cone drivers with heftier magnets which would also improve drive ability of these speakers for folks that only use one amp.
