For High-Resolution Audio files, the digital amp and specialized tweeters reproduce every subtlety, so you can hear each note as the artist intended. For MP3s, digital processing software upscales compressed music to restore lost detail.

2.1 channel system for powerful audio

Get 90 W of powerful sound from a 2.1ch speaker system. Two mid-range magnetic fluid speakers deliver pure, crisp vocals and complex melodies, supported by Wide Dispersion Super Tweeters which produce soaring highs and a wide soundstage.

Boost your bass with a 2.72 in subwoofer and dual passive radiators

Get big bass lines from a compact speaker. Dual passive radiators work with a 2.72 in subwoofer 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.
