A225-M

Full Range Accurate Subwoofer
Don’t think of a subwoofer, think of adding an extra low frequency way to your monitor.

Our Subs are designed and calibrated to seamlessly extend the low-end of any of our loudspeakers and with and overall flat frequency and phase response. The result is remarkable when reproducing low frequency acoustic instruments. The tight, accurate, perfectly controlled bass allows hearing all details down to 24 Hz.

The A225-M is a powerful subwoofer and perfectly fits the A21-M and two units perfectly fit A25-M.
