EM-R
The EM-R is a premium high-performance in-ceiling speaker that uses a larger
8-inch aluminum woofer and angled Folded Motion
™
tweeter for ultimate-
performance in-ceiling applications. The speaker is rotatable to aim sound.
A robust mounting-lock system allows quick, trouble-free installation. When
not in use, the constant-control mounting locks are held securely within a
self-contained housing. When moved into place during installation, they
couple the speaker’s chassis firmly to the ceiling. And if the speaker is ever
removed, the locks retract and latch themselves back in their housings.
Installers rejoice as the Folded Motion tweeter is mounted at an angle,
allowing the entire speaker to rotate to aim sound precisely where you want it.

MartinLogan’s proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This
precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of
any source.
