Amp Speaker Pairing


My amplifier is the Pass Labs XA 60.8 monoblocks.  These output up to 60 wpc in class A and from 60 to 130 wpc class A/B.  The room I use is a generous size 19’ wide, 32’ long with 9’ ceiling.  Looking at the WilsonYvette speaker, the website recommends a minimum amplifier power requirement of 50 wpc.  So my amplifier falls within the minimum qualified amplifier power qualification.  I am seeking input on the sufficiency of my current amplifier to drive the Yvettes “comfortably” (headroom, dynamic swings) in a generous size room.  Mainly listening to rock/soft rock/blues.

Wouldn't the Yvettes be on the small side for such a large room? In my 12' X 34' w/cathedral ceilings room, I use 12" Tannoys which work very well for my purposes.

Why such a small speaker in such a large room?

 Thanks very insightful and helpful.

The Yevetts may in fact be too small for the room.  My only excuse is that I auditioned and like the Wilsons but would be the first to acknowledge ... I really don’t know what I am doing.  Thanks for the suggestion.
