Earthquake Sound SUB6 6.5 8-Ohm 150-Watts Passive In-Wall Subwoofer

Earthquake Sound SUB6 In-Wall Subwoofer

The Earthquake Sound SUB6 is a passive in-wall subwoofer built for discreet low-frequency reinforcement in home theatres or multi-room audio systems. It mounts flush in walls or ceilings and relies on an external amplifier for power. The 6.5-inch driver handles 150-Watts MAX and presents an 8-Ohm load to the amplifier. A built-in 100Hz low-pass filter at 12dB per octave keeps vocals and instruments out of the bass channel.

Installers wanting hidden bass without

This unit suits new-build or retrofit projects where a visible subwoofer is undesirable and an amplifier with spare channels is available. It is not for listeners who need output below 30Hz, rooms larger than the driver can pressurise, or systems that lack a dedicated subwoofer amplifier channel. Buyers wanting a self-powered solution or wireless connectivity should look at a different product category.

150-Watts MAX handling with 30Hz–1kHz response

The 6.5-inch cone with a 25mm voice coil and wide surround delivers usable output down to 30Hz at moderate listening levels. Sensitivity of 86.7dB means the external amplifier must supply adequate current for dynamic peaks. In large open-plan spaces the single driver reaches its excursion limits quickly, so headroom runs out well before reference-level home-theatre demands are met.
