How to get the impact of a live concert?

2kw per channel in your living room.

Yep, in general, the quick recipe to best get impact of a live concert is larger speakers with more and or larger quality drivers, the highest power and current quality power amp you can manage to drive them, and a quality source to feed it all.

Bottom line, you need an effective combo of both quantity and quality. ALso larger and/or less lively rooms will require more quantity than others. In smaller/livelier rooms, less can be more.

The only speakers that I ever owned that reproduced the sound I would hear at a concert are Klipschorns. I am sure there are others, but I'll bet they are horn designs as well.

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.
