The U1 is a compact, elegant yet technologically sophisticated powered subwoofer of acoustic suspension design. It has been engineered to extend the bass range of our Evolution M5 or M6 monitors, or any other monitors of similar frequency range, with tight, accurate and powerful performance.

Of all Evolution subwoofer configurations, the U1 is the most flexible for free standing placement, as its dual-woofer side firing design allows the U1 to be tucked away unobtrusively, relatively close to furniture and walls.

The entire U1 system consists of three electronically matched components: the W1 subwoofer enclosure with dual bass drivers, an A1 monaural amplifier, and an X1 Active Crossover.

The W1 cabinet features two opposing 12" woofers in a single enclosure delivering powerful bass down to 25Hz. The drivers, mounted on opposite sides of the enclosure, work together to eliminate cabinet vibration caused by low frequencies. Each driver employs an aluminum cone attached to an aluminum former (the cylinder on which the voice coil is wound). This assembly acts as a massive heat sink which reduces distortion and heat buildup under demanding loads.

The A1 monaural amplifier delivers 250 watts rms to the W1. The A1 is a Class G design, known for efficiency and cooler operation than many other amplifier designs.

The X1 Active Crossover provides fine tuning of the U1 subwoofer system, allowing seamless integration with Evolution and other satellites, and helping eliminate many common low frequency problems caused by room interaction.

This unique combination of electronics and high tech woofer design offers tight, articulate bass for music reproduction and the high output and dynamic range needed for the full enjoyment of movie soundtracks.
