Dynaudio 18S

The Dynaudio 18S is an active subwoofer that allows you to hear the low end of your mix with amazing clarity. Dynaudio have applied advanced DSP modelling technology that acoustically matches 18S to any Dynaudio Pro Studio Monitor from BM Classic, LYD and upwards, turning two-way systems into three-way set-ups. Its punch is delivered by two of Dynaudios brand-new MSP+ Hybrid Drive units and a 500W amp for absolute control and power.

Getting the 18S to match seamlessly with Dynaudios professional monitors is key for absolute accuracy when mixing and mastering. That has meant assessing the acoustic characteristics of each of Dynaudios popular high-end studio speakers and creating custom performance maps for each one. And it’s future-proof: when Dynaudio add new studio speakers to the line-up, also release a firmware update for the 18S to add their performance maps – so it can grow along with your needs and equipment.

With this information at its disposal, the 18S’s display and menu system lets you select the specific Dynaudio speakers you’re using in your monitoring setup. This means the roll-off can be tailored perfectly to suit. And, if you combine a LYD 48 stereo or surround setup, you’ll essentially have a full-blown four-way monitoring system at your disposal.

The 18S has a selection of RCA or XLR connections for flexibility with your studio setup, and comes with a number of handy features to help more advanced systems too. This includes the ability to set a time delay to ensure the sub and speakers are working perfectly in sync: all you need to do is enter the distance from the sub to the speakers and the sub adjusts itself automatically using both time and phase delays.
