With the TrueBass 18S, Dynaudio applied advanced DSP modeling technology that acoustically matches 18S to any Dynaudio Pro Studio monitor from BM Classic, LYD and upwards, turning two-way systems into three-way setups. Its punch is delivered by two MSP+ Hybrid Drive units and a 500W amp for absolute control and power.

Getting the 18S to match seamlessly with Dynaudio professional monitors is key for absolute accuracy when mixing and mastering. 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, meaning the roll-off can be tailored perfectly to suit. Plus, 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 also 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. This includes the ability to set a time delay to ensure the sub and speakers are working perfectly in sync. There’s also a full three-filter parametric EQ to easily defeat room modes that could affect the accuracy of your final recording.
