How to get the impact of a live concert?

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.

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.
