Bi-amping Revel Ultima Salon 2

[The Sandman]

I currently have a pair of XA 160.5 amps and I'm considering the purchase of the Revel Salon 2 speakers. These speakers are relatively inefficient and known to be power hungry, so I'm thinking about bi-amping them if need be.


Speaker specs:

• Four-way, reflex-loaded, floorstanding loudspeaker. Drive units: 1" (25mm) beryllium-dome tweeter, 4" (102mm) inverted titanium-dome midrange driver, 6.5" (185mm) titanium-cone midbass driver, three 8" (210mm) aluminum-cone woofers.
• Crossover frequencies: 150Hz, 575Hz, 2.3kHz.
• Sensitivity: 86.4dB SPL/2.83V/m (4 pi anechoic).
• Impedance: 6 ohms nominal, 3.7 ohms minimum at 90Hz.
• Recommended power: not given.

If I were to run the mids and tweeters with the XA 160.5's, what would be the recommended Pass Labs amp(s) for the woofers?

We have a pair of Salon 2s here, and I would say that you might want to simply
try them with just the XA160.5's before you worry about it. Our impression
is that there is adequate power and current already.

Thank you sir! To be honest, that's what I was hoping to hear.

What's your impression of the Salon 2s?
