Pass XA 30.5 with Revel F 208 ?

Don c55,
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.
Charles,

Thanks Radni, I am almost there deciding on coincident technology, the only problem being, I have to ship these to india. I was wondering if Trimph Extreme II would be ok. Can anyone tell how big a compromise it would be from the victory series to Trimph Extreme II. Can the difference be compensated by adding quality subs?

I have Revel F52 with a PASS X250.5 90% of my listeing the amp stays in CLASS A which is about 30 watts. Its a great match.

You can get F52's for around 3K used and they are better than the 206 or 208.

I like the revles better than B&W 801 matrix III and B&W 802s I also had Magies 3.6's Spendor SP1/2e, Viro III's and the revels are the ones I have kept for over 4 years now. My next upgrade will be to the salon's

Fin1bxn,

I went from F52s to F208s. I have them in the same room, with the same equipment. This is a very subjective hobby, but to my ears to say the F52s are better is crazy; different yes, but better?! The F52s are more of a point source. The F208s are more dynamic, better bass, bigger soundstage,and when properly setup the F208s image better. I submit most people will say the F208s are a little clearer than F52s. I won't say there is a night and day difference, but most people will hear the difference.

Don_c55 and Charles1dad, I do agree that an excessive high level of AVERAGE SPL is for idiots, however there can be a very wide margin between average SPL and peak SPL with some music, especially classical. The SPL numbers to be used in the calculator I provided in the link are peak, not average. Also, this same calculator is found in many places on the web, as it factors in using a pair of speakers, room gain, and listening distance.

So how high can the peak SPL actually be at the listening position with a normal average SPL? Then please read the comments by Almarg, a well respected contributor to this forum, in this thread, especially the last paragraph of his 2nd post.

Here is another paper worth reading about power needed and peak SPL in a "good hi-fi system",

http://www.daedalusaudio.com/images/loudspeaker%20sensitivity.pdf

Depending on the type music and quality of recording, it is very possible at the listening position to have a peak SPL of a 105db, while the average SPL is only 75db.

Bottom line is the required power is not for average SPL, but for that peak SPL, which is much higher than a lot of people think, even though it is only for a split second. Having less power than required for the peak SPL will restrict the dynamic range, and clip the amp for that split second.
