Miami Mo mentioned the ONLY downside I have found to the L1. If you want to sit in a far corner and barely hear the music, you're out of luck. It disperses the sound so well that it covers all areas equally.
It can be set to sound as warm as you like. In actuality, I run mine mostly flat, with just a little boost on the low end. I e.q. from my keyboard, or mixer if I use one, but they are mostly flat also.
It is designed to be transparent, and it is. If you are used to a certain "coloring" of sound from the system you use, it will sound different. There is no muffling to cover boo-boos! However it can be totally equalized either from the remote or from a mixer.
I've had totally positive reviews from audiences and employers alike.
