While powered on, the speakers produced a very audible

In a studio or a small-ish venue (25' x 50' or less) it has enough power and sound output to provide most of the low end

Rockville has produced a fine powered subwoofer for smaller rooms

This allows a user to feed either a stereo signal with the appropriate cable or a mono bass output with a Y-adapter cable (which I prefer) to each of the two inputs, thus maximizing the available power applied to the driver

Just not enough power for

Great range and unlimited power
