Honest opinions on my two picks of loudspeakers

I have never heard either speaker but just eye balling them I would go for the Revels. I have never been fond of multi driver designs. I have never heard one that I liked. Two midrange drivers should be the most you should ever need. 10 and you have lost me. Mcintosh does not have a history of producing great loudspeakers. But, it is your system and you should listen carefully to both with the music and volume you like.

Shawn, It was the Grateful Dead's wall of sound designed by John Curl.
He did use Mac amps but not Mac speakers. It turned out to be too expensive and difficult to move from one venue to the next. But, it was knock out.
If you want clean SPLs get the new Klipsh Cornwalls version 3 I think. They will blow your doors off with 10 watts:)

Steakster, Bear is not an electrical engineer. Who do you think was telling bear what to do! Bear however was quite the character and indeed the wall was probably his idea in looking for a grand expression of the concert audio system. Like I said before it was unfortunately a royal PITA and did not last long and it really did not have to. It would not be long before excellent commercial sound systems would hit the market that were made to deal with the rugged life of portable sound equipment.
The absolute best concert system I ever heard was back in 1973, Return to Forever. What a system, what a band. I skipped a week of classes and followed them around New England.
Shawnscola, excellent! Do tell us how you like them. I have not heard the new ones yet. Do heed mcryn to this extent. I listen at 95 dB all the time but I always warm my ears up for 10 minutes at lower volumes and allow them to accommodate. Once your ears adjust themselves for louder volumes Rock and Roll. You can get a sound pressure meter for 20 bucks on line. With warmed up ears 95 dB is safe for people with normal hearing. 100 dB is safe for short periods again only with ears that are warmed up. 105 dB will cause hearing loss in just about everyone. I am an anecdote but at 65 I can still hear 18 kHz. I would prefer to think it is because I have always been careful how I expose myself to loud noises. Everyone on my father's side was deaf as a door knob by the age of 80. Fearing that end I always wore hearing protection shooting guns and using various machines. By 65 my father was already noticeably hard of hearing. So I am already doing better than he did. Anyway I listen at 95 dB virtually every day. It is certainly not concert loud but it is loud enough to give you the appropriate visceral impact if you have good bass reproduction. 

Enjoy,
Mike
