Pass XA 30.5 with Revel F 208 ?

Hi Kartikeyp,
The Coincident Triumph Extreme would be an excellent choice in my
opinion. It would mate well in a room of your dimensions . This speaker is
very easy to drive( relatively flat 8 ohm load) and your Pass amplifier would
simply coast, sound effortless and remain in class A probably 99.9 % of the
time. I believe that you'd love this Pass- Coincident pairing.Coincident
speakers are very natural, transparent and most of all musically involving.
If you're seeking analytical hifi then these speakers won't suit you. Gon
contributor Brownsfan just bought these Triumphs and is ecstatic with their
sound quality. Sub woofers are of course an individual case by case
decision.
Charles,

Thanks folks. I appreciate your inputs. Narrowing down to a few brand / models is a big challenge in the HiFi jungle. I think i ll start looking for coincident models soon.

The calculator you provided a link to is useful and in my experience, accurate. I can be listening at levels averaging 80 dB but with music with real dynamic range, peaks will hit over 100 dB. That's the issue the XA30.5 will hit with 88dB speakers. And at my 3.5 m listening distance, that's why I said my speakers sometimes are a bit light on the octane.

Other factor to consider which is virtually never really mentioned is that if you really do have enough power on tap, speakers begins to experience dynamic compression at higher spl levels. Said another way,mspeakers can run out of steam before the amp can.

Were I serious about a XA30.5 I would concentrate on speakers running at least 92dB or more efficiency. The whole pointof the XA30.5 is to run it in its sweet spot, and if you're relying on the power on tap when it crosses over to class B operation, might as well get an X150.5

Sorry to be slow. Currently I have Coincident Conquests, Triumphs and Triumph mini's-Whole theater.

I have this exact setup in my bedroom (19L x 18W x 10H), F208 with XA30.5. I have no problem playing music loud. The combination makes glorious music. Love the pair.
