Greater output. Consistent control

A dedicated 300W amplifier delivers greater output and dynamic headroom, ensuring low frequencies remain composed even at higher listening levels. Power with control.

8” Active Driver with Passive Radiator

An 8” active driver works alongside a passive radiator to move more air efficiently - increasing depth and output while maintaining precision. This delivers confident low-end performance from a compact enclosure.

Digital Signal Processing (DSP)

Integrated DSP manages frequency response and output in real time, maintaining stability and clarity as listening levels rise. Bass remains controlled and articulate, even during demanding passages.

Designed to integrate

Not every system requires a large, imposing subwoofer. MSX Sub 300 combines considered proportions with clean lines and refined finishes, allowing it to integrate with your room rather than dominate it. Available in refined black or white, in a classy matt finish that won’t distract.

Bigger bass impact

Sub 300 delivers deeper, more authoritative low frequencies, giving home entertainment systems the scale and physical presence that film, TV and music demand.

High-powered performance

This larger active subwoofer is engineered to move more air with ease, producing richer, more dynamic surround sound that fills bigger rooms confidently.

Cinematic low frequencies

Designed for movies and TV, the enhanced bass output adds weight to explosions, atmosphere to soundtracks and realism to every scene without overwhelming detail.

Music with depth and drive

This subwoofer brings added substance to music, revealing texture and timing in bass notes so tracks feel grounded, controlled and engaging.

Room-filling control

Advanced tuning and adjustable controls allow precise integration with your system, ensuring the Sub 300 blends seamlessly for balanced surround sound.

Built for larger spaces

Cambridge Audio heritage

Built for larger spaces

Pair MSX Sub 300 with MSX20 - or integrate it into a larger MSX system, for greater scale and headroom. Its compact footprint allows flexible placement - in corners, beside furniture or within dedicated media spaces, while delivering consistent low-frequency performance across the room. It also integrates easily into systems that demand higher output and deeper extension.
