Sub A225-M – Powerful and 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 28 Hz and even down to 24 Hz with our larger model.

What our users say

The Sub A225 brings a relief, a natural depth to the A21, thus making the decomposition of the plans that make up an incredibly intuitive mix.
