EWSLA63 Edgeless Line Array In-Wall LCR Speaker

The Earthquake new EWSLA63 (line array in-wall system) benefits from 57 years of acoustic discoveries dating back to 1957. Line array system is a directive way of sending sound wave from the speaker to the listener with minimum wall reflection. You listen to the music, not the room. In a typical room, the EWSLA63 requires 4 times less power than a single source speaker to achieve the same sound pressure level at a listening position. As the power is reduced, so are the reflections.

The EWSLA63 implements an array of six 3-inch speakers that are positioned to minimum phase delineation. The frame is made of AL6061 (aluminum alloy) which kills vibrations. A complementary Turn-n-Lock™ mounting mechanism makes the installation a snap.

With an edgeless design, slim profile and magnetically attached (paintable) grille, the EWSLA63 delivers sound clarity and style to any home theater.
