Pass XA 30.5 with Revel F 208 ?

If a speaker seems "light on octane" driven by a 300 watt amp,
that's quite a very inefficient speaker that's wasting good quality power
(Pass amp) IMO. Its never been clear to me why some speakers need to
draw so much power to come alive, just a curious observation and not
criticizing.

Hi Jmcgrogan2,
I was responding to the post by Zavato written above my comment. I'm familiar with the specs of the highly regarded Pass XA30.5.

I share your opinion concerning the excessive high volumes and the real threat of potential hearing impairment (irreversible). But ultimately to each their own. I attended a jazz concert last night in a modest size venue and it was unamplified. My friend's phone SPL app measured low- mid 90s db on average from our seats 20 feet away. That is definitely loud enough for me and at home I'd be listening 10-15 db lower. So it's an individual comfort level choice.

Hi Tls49,
I understand your point and priorities. I don't desire or seek those high peak levels, and I've heard systems capable of reaching 105-110db levels. That doesn't impress me and isn't an important personal criteria. But of course that's just me and I'm in no way critical of your preferences. We all aspire to achieve the sound/audio systems that fulfill our particular goals. I wish you the best in your sonic endeavors. I'm a confirmed fan of Almarg's many quality contributions.

Tls49,
I appreciate your kind comments very much.

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.
