S7i
IN-WALL SPEAKER
The next level in-wall with Directivity control to well below 1kHz while enabling a DPC array and timbre matching not only in the raw materials but in the critical frequency response, power response, and phase. In addition, the S7i is THX Dominus LCR certified with the same amazing Sensitivity and THD as our famous S7t tower. A true value in the largest sized home theater in-walls compared to almost any in-wall on the market and can be utilized as an LCR with an acoustically transparent screen or as an LR in the Media room.
