Pro Audio Subwoofers series

Our 9S and 18S subs feature long-throw 9.45in (24cm) woofers that are designed to be equally efficient for stereo and surround monitoring applications, handling the ultra-low frequency range, are at the heart of these subs. The 9S features one woofer and the 18S has two in a push-push opposing design with a woofer on each side.

Compact and highly acclaimed

The 9S is just as compact as our previous and highly acclaimed BM 9S II sub, yet with a performance that is comparable to the larger BM 14S II sub.

Regardless of whether you add it to a LYD 5, 7 or 8 stereo or surround setup – or use it with our classic BM series of studio monitors – it delivers a full, yet focused and revealing performance. You’ll be able to make accurate mixes that translate great to any format and playback system. And if you couple the 18S with LYD48, you’ll essentially have a powerful four-way monitoring system that’s equally capable of delivering high SPL and low-volume precision.

Powered by a high-end 300-watt Class D amplifier, the 9S long-throw driver delivers low-end extension and SPL performance that significantly outperforms the BM 9S II it replaces, while still preserving detail and precision. The 18S is powered by a 500-watt amplifier and features a powerful DSP engine and built-in presets for Dynaudio Pro studio monitors, as well as time-alignment functionality and a three-band EQ to defeat specific room modes. Further, the new subwoofers come with double front baffles, adjustable low-pass filters from 50Hz to 150Hz and SAT output with defeatable high-pass filter, all of which is housed in sealed cabinets.

Finally, the subs have a signal-sensing auto-power circuit that saves energy when not in use, and for larger rooms, it is possible to daisy chain more 9S or 18S subs, having the first unit control the overall volume for all of the subs.

If you ever considered upgrading to a 3-way or 4-way monitor system, now's the time to act!
