How to get the impact of a live concert?

the closest to live i ever heard was with the Wilson Audio WAMM system consisting of two (18") subwoofer cabinets in the back and a pair of "trees" with
different speaker arrays on them that could be pointed independently and a complex crossover as well to tune the system to the room and listening position.
IMHO Wilson should re-introduce this concept again even if it is just for experimentation to see what is possible. anyway, the sound was so enveloping and powerful (loud but not ear-shattering) on a live rock concert and a symphony recording i was fairly speechless afterwards. but you would need a room 25 X 30 to set the WAMM up properly. it sure would be nice if everyone could get a chance to hear something like that- but i guess the easiest is of course to buy tickets and attend a concert (if you can get good seats).

Roxy,

My OHMs do it for me as well but require a larger amp to do it best.

They are not horns nor conventional box/dynamic speakers. The OHM CLS Walsh driver configuration used is fairly unique.

I have heard some very large and expensive conventional box design speakers do very well with suitable amplification. Same with horns, but with fewer watts.

My Aerial 10t in 17x22 room do it with 2x sunfire SRA biamp that push them with nearly 1kw per each. They spec to blast 140db/m of SPL. Klipschhorns would cripplecrack after they reach 125db/m.

Also remember to consider that continuous SPLS above 83-85 db or so are generally regarded to be harmful to our ears. SO, practically, be careful about what you wish for in terms of loudness and dynamics like a live concert. You just might get it...too much...too often. Better for a music lover to preserve their hearing as best as possible. A very loud, very good, very dynamic home system can literally be the equivalent of a lethal weapon to your ears.

Again, I'm not talking about volume. I'm talking about the impact, dynamics, feeling, whatever you want to call it. For me, that's more import to making the music sound live, than throwing a huge soundstage or getting every note exactly right. That of course, is just my opinion.
