Edgeless In-Ceiling Pair

The Earthquake Sound ECS 4.0 is a pair of ultra-compact 4-inch in-ceiling speakers designed for discreet audio in residential or commercial spaces. Each unit features a full-range driver housed in a self-enclosed, humidity-resistant cabinet. Paintable edgeless grilles allow the speakers to blend into ceilings or walls without visual interruption. They are sold as a stereo pair for immediate multi-room or overhead use.

Suited For Discreet Installs

These speakers suit owners wanting background music in kitchens, bathrooms, garages or covered outdoor areas where humidity resistance matters. The toolless mounting clips enable fast DIY placement into standard cutouts without specialised equipment. Buyers needing deep bass extension, high-output main-channel performance or dedicated subwoofer integration should look at larger cabinet designs. The compact driver size limits low-frequency authority in open-plan living rooms.

50-Watt Overhead Coverage

Each speaker handles 50 watts of power, providing ample headroom for Dolby Atmos height channels or distributed stereo audio in small to medium rooms. The 99 millimetre cutout diameter and shallow three-inch mounting depth fit tight ceiling cavities where deeper enclosures cannot go. In large open areas or high-SPL home cinema setups, the 4-inch driver reaches its excursion limits before reference-level output is achieved. Multiple pairs extend coverage evenly across wider zones.

Questions about this item

What amplifier power do I need to drive the 50 watt speakers?

An amplifier rated for 50 watts per channel into 8 ohms will match the ECS 4.0 output rating.

Can I keep my existing 99 mm cut-out holes when swapping to these?

Yes, each speaker fits a 99 mm diameter hole with a minimum 3 inch depth.

How do I verify Dolby Atmos height channels are active after install?

Play Atmos test tones; you should hear distinct overhead effects from the pair.
