About Dynaudio 18S

If you're seeking to elevate your audio production to new heights, the 18S True Bass 500W Dual 9.5" Powered Studio Active Subwoofer is the perfect addition to your professional sound setup. This advanced subwoofer is designed to enhance your mixing and mastering precision, ensuring your tracks translate flawlessly across all playback systems.

Engineered with cutting-edge DSP modelling technology, the 18S True Bass subwoofer acoustically aligns with any Dynaudio Pro Studio Monitor, including the BM Classic and LYD series. This seamless integration transforms your two-way systems into dynamic three-way setups, delivering a powerful punch with its dual MSP+ Hybrid Drive units and a robust 500W amplifier for absolute control and power.

The 18S True Bass subwoofer is designed for future-proof compatibility. As new studio speakers are added to the Dynaudio line-up, firmware updates will be released for the 18S, adding their performance maps. This ensures your subwoofer evolves with your growing needs and equipment.

The 18S's intuitive display and menu system allows you to select the specific Dynaudio speakers in your monitoring setup. This tailors the roll-off perfectly to suit your system. Pair it with a LYD 48 stereo or surround setup, and you'll have a comprehensive four-way monitoring system at your fingertips.

This high-performance subwoofer offers a selection of RCA or XLR connections, providing flexibility for your studio setup. Advanced features include a time delay setting to synchronize the sub and speakers perfectly, and a three-filter parametric EQ to counteract room modes that could impact the accuracy of your final recording.

The 18S True Bass subwoofer introduces a newly designed driver, crafted from aluminum with a paper backing and an MSP dust-cap on the front. This unique combination ensures the perfect balance between stiffness, lightness, and damping, delivering the best performance possible for subwoofers.

The 18S True Bass 500W Dual 9.5" Powered Studio Active Subwoofer comes with presets designed to work with a range of monitors, including the BM6 Classic, BM15 Classic, LYD 5, LYD 7, LYD 8, LYD 48, and M5P.
