Powerful sound from a slim profile

Despite being compact in size, the SRS-X55 delivers 30W RMS total output power through 2.1 audio channels. Experience full-bodied, balanced audio with two 38 mm full-range speakers and a 58 mm subwoofer – so you can enjoy your music with clear, powerful sound whatever the volume.

Boost your bass with a woofer and dual passive radiators

Get big bass lines from a compact speaker. Dual passive radiators work with a woofer and react to the movement of air through the speaker, artificially creating space in the speaker cabinet. This space allows more air to flow through the speakers, enabling even smaller units to deliver superior sound—especially at low-end frequencies.

S-Master digital amplifier: true sonic purity

Enjoy the best of digital audio with the S-Master digital amplifier. Using a simplified, full digital signal path, the S-Master amplifier reproduces digital audio signals without the multiple analogue stages required by conventional amplifiers. The result is not just more power, but significantly less distortion caused by heat build-up.

DSEE restores detail to your digital music

Boost the quality of your compressed music files. When an original music source is compressed, it loses the high frequency elements that add detail and richness to your favourite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high quality sound that’s closer to the original recording.
