How to get the impact of a live concert?

Also often more current delivery with many speakers, probably including the Gallo's but less so for the Klipsch.

The Gallo bass drivers fire sideways as I recall so that alone would probably up the ante in terms of power needed to deliver a certain level of impact at the listening position.

Proper damping of the speaker by the amp is very important.

Build quality of drivers and the overall speaker design is important also though size does of course matter when it comes to attempting live concert like impact.

A good sub can certainly help if integrated well, though that can be tricky to achieve well in many cases.

I love the Bel Canto ref1000m/OHM 5 omni speaker combo I use in particular in this regard. This combo does it all in regards to reproducing the impact of a live concert in my room. I can't imagine it being any better.

Take a moment and go to Audio Asylum. There is a current thread in the 'General' forum discussing the importance of Dynamic's and what that term means. It is an excellent post and some of the contributors also discuss the practical ramifications of trying to get good results at home.

It is not definitive but I highly recommend it to anyone who wants to approach the goal of live music at home, or at least wants to know why you won't ever get there.

The Audio Asylum thread is a good one with valid points.

Its not easy and requires first knowing what "there" means to you, and then a lot of work and experimentation over time perhaps to get there. It took me years (decades actually) but I do not necessarily agree that one can never get "there".

"There" will always be a reproduction with some limits/variations in practice, but these can be made insignificant to the point where it really should not matter to most. Money, time, and knowledge are certainly the keys.
