Soundstage and explosive dynamics?

For explosive dynamics you need a large speaker with the following specs:
1-dual 15" woofers, at the minimum.
2-at least a 2" compression driver for the highs
3-high efficiency ion less than 96 dB
4-all the above plus bi-amplification, with a bi-amplifie large system you have a good chance of reaching your goal of explosive dynamics.
I have one such system, it is JBL 4350, a four way bi-amplified monster.
I mainly listen to classical, these JBL's can do justice to uncompressed orchestral recording like no other speaker with a very transparent full range sound.

I can recommend tekton impact monitor and the new technics monitor reviewed by Herb Reichert.

+1 Vahes but I would add that an exponentional horn tweeter can be substituted by a BIG beefy mid range and a conventional tweeter. Horns work great but there are a few powerful non-compression mid drivers out there.
