I have its little brother - the 816V. Actually, if you are considering the "W" version, the 816V is more like a little cousin. The "W" version drivers should have much better quality construction. The cabinet design creates a decent amount of bass in my small listening area - even with just one woofer per cabinet. FWIW I listened to several other speakers in the 816v price range - and some at higher brackets. I preferred the 816V's clarity and balance.
They are easy to power. My little 50 watt tube amp is more than enough for the 816V.
A tip - if you get them, the metal tweeter cover can pop off using a ball point pen or something similar. It is only held on by the tweeter magnet. Revmoving the cover opens up the high end a bit.
If you would like more info on the "W" series speakers, there is a Stereophile review of the Focal Chorus 826W 30th Anniversary Edition loudspeaker here:
