Excerpt: I run sound for a male gospel singing group with piano. I wanted a powered speaker for mains capable of small to medium size venues. I listened to JBL, Mackie, Peavey, and several others with similar power ratings, some with higher power ratings. I bought the MSR400. The sound is very clean and true especially for vocals. Excellent balance between lows and highs, and the power is more than adequate for even some larger rooms.
Excerpt: Crystal clear sound. I use 2 of them conected to a yamaha mixer and the sound is so true. I'm using AKG mics. The bass is very very powerfull for a 12'' It achieves all frequencies. I seriously recomend this speaker to everyone.
