well, i had rick make me these speakers two years ago. whenever i happen to play an acoustic guitar along with the music or even sing along, it sounds like my playing/singing is blending right in with the sound the speakers are putting out. these speakers seem to be a very accurate reproducer of sound waves. remember these are the ones with the 7 inch paper coned illuminator series scan-speak mid-woofers and the 70-20xr RAAL ribbon tweeter. they are the rear ported version as well. (i don't use a sub) you can listen to these as long as you want and you wont be tired of it. i'm planning on getting a pair of mono-block class A amps and listen to them really shine. i use mono-blocks now, but they are just class A/B. if anyone else has these speakers i'd like to hear what you think of them, and anyone else with a comment on my review is welcome too.
