Earthquake Sound ECS6.5 6.5″ 300 Watts Max 8 Ohm Edgeless Ceiling Speaker (Pair)

The ECS6.5 Edgeless Ceiling Speaker is one of Earthquake Sound’s most valued speaker lines. Designed with aesthetics (WAF – Wife Approval Factor) and sound quality in mind, the ECS6.5 Edgeless Ceiling Speakers seamlessly blend into their surrounding as they provide a lifetime of durability and high-end performance.

Designed like no other, the Edgeless series is a prime example of Earthquake’s continuing pursuit of audio excellence: “the goal is to seamlessly blend into any interior décor and to reproduce the sound of a concert hall or the sound of a movie sound track in any room with these speakers; with seamless super low profile, these speakers blend perfectly with any décor.”

The Edgeless speakers deliver deep, natural response from the design of their advanced cones and surrounds. Superb sonic accuracy is guaranteed by the utilization of a stiff light weight Kevlar cone in the woofer and silk dome neodymium tweeter. Additionally, you can customize the sound of the speaker with a +/- 3dB adjustment selector switch that optimizes the sound to the acoustics of the room and the listener’s own personal preference.
