Forget about what other small PA speakers sound like. Especially forget what so-called "powered" speakers sound like. The active SRM450 is that different. It has tight, steel-fisted bass to below 55Hz and detailed, articulate treble out to 20,000Hz. Midrange is warm, natural, and free from ear-fatiguing harshness. The SRM450 has astonishingly wide dispersion that lets your whole audience hear clearly, whether they're in the front, back, or way out on the sides of the room. And above all, the SRM450 cranks! Without a hint of distortion, it effortlessly achieves sound pressure levels that would melt conventional speakers into a pile of molten slag.
