Are you tired of trying to gauge the bottom end of your recordings? Dynaudio's 18S is a serious, pro-grade subwoofer that gets you tightly down to 16Hz. You'll feel the crush of a well-recorded kick drum. The full weight of a 5-string bass. You'll also be able to identify any low-frequency mud that needs to be cleaned up. To properly record frequencies this low, you've got to be able to hear them. Adding the 18S to your monitoring setup opens up a new world of performance that lets you record, mix, and master with meticulous accuracy — and deliver tracks that translate perfectly to the world beyond your studio. Employing dual-opposing 9.5" long-throw MSP+ Hybrid Drive units and 500 watts of Class D amplification, the 18S features intelligent DSP that seamlessly tailors its performance to popular Dynaudio high-end monitors, for true full-range monitoring that will help you make better recordings.
