With limitless applications and sound quality in mind, Earthquake Sound is proud to release the new ECS 4.0 Edgeless In-Ceiling Speaker. The small footprint of this 4" full-range speaker was made for a variety of indoor as well as outdoor applications. The self-enclosed design with humidity resistant components provides users with a broader range of installation options such as bathrooms, kitchens, and outdoor living spaces are just a few examples.

Installation is made painless from a toolless mounting system that makes your installs faster and more efficient by simply pushing the speaker into any 99mm diameter hole with a depth of 3 inches. The edgeless and paintable grille further enhances this speaker by allowing it to vanish and not interrupt thedécor of the room. The ECS 4.0 is built to perform and complement the space in which it is placed allowing youto enjoy music and audio in your home or commercial space.

Key Features:

  • Impedance: 8 Ohm
  • Sensitivity: 84 dB
  • Frequency Response: 80Hz–10kHz


Optimized For Dolby Atmos®

The ECS 4.0 is optimized for Dolby Atmos. The accuratereproduc­tion of Atmos overhead code depends on isolating the room from compromising event placement with reflections. The highpass fil­tering ensures that users will listen to the Atmos code and not a di­luted and altered room response.

Kitchens, Bathrooms, & Outdoor

The self-enclosed and humidity-resistant design allows the user to place this speaker in areas where humidity might be a concern. Enjoy audio from your bathroom, kitchen, and outdoor spaces.

Single-Handed Mounting System

Spring-loaded and tool-less mounting clips make installation simple, secure, and more efficient so your job is done quicker.

3" Mounting Depth

The small mounting depth requirement of the ECS 4.0 gives users more mounting options for either in-ceiling or in-wall applications as well as covered outdoor environments.

Premium Neodymium Magnets

ECS 4.0 is equipped with the highest quality neodymium magnets on the market making the speaker smaller yet more efficient than any other speaker magnet material.

Long-Lasting Rubber Surround

The long-lasting and sag-resistant rubber surround will ensure that the speaker performs exceptionally well through many years of use.

Thermally Conductive Cone

ECS 4.0 is manufactured with aluminum cones for added thermal stability with less distortion and can greatly withstand weathering in humid environments such as bathrooms and outdoor areas.

Edgeless Paintable Grille

The edgeless, slim, and paintable grille on the ECS 4.0 allows the installer to further customize the speaker so that it can perfectly match the decor of any room.
