The Dynaudio Custom Studio series S4-LCR65 system is modular; its separate woofer and tweeter modules are designed to fit snugly in the spaces between 16in on-center wall-studs. That means you can configure a full three-way LCR array with no modifications and no more effort than it takes to spec the rest of the system.

The tweeter modules can be placed either way up to optimize the system for the listening position, while a rear switch lets you match their power setting to the number of woofer modules you’ve chosen. There’s also a passive filter bypass setting to unlock an unlimited range of fully active LCR system configurations.

Dynaudio's engineers wanted to make it as easy as possible to install a larger array in one go, which is why magnetic fastenings hold everything securely together if you’re not separating the modules. The S4-LCR65 system also uses the exact same unique clamp-and-lock mechanism as the rest of the Dynaudio Custom Studio range.

The frames are pre-installed during construction or renovation (the house can be finished around them). Then, when it’s time, your expert installer comes to mount and fine-tune the speakers – so it’s exactly right, first time. All without damaging the décor or having to pull anything apart.

Like the Studio series round in-ceiling speakers, the rectangular in-wall versions have a tweeter-level switch and include paintable magnetically attached grilles for an even more personalized set-up. And, of course, they use Dynaudio’s legendary 1in soft-dome tweeter and MSP driver technology – the same stuff you’ll find in our celebrated hi-fi, automotive and pro-studio speakers.
