All-wooden cabinets of the subwoofer and satellite speakers complement any style of your room's decoration, moreover, minimizing acoustic resonance and reducing distortion.

The 8" bass driver of subwoofer, with the cast aluminium frame and benefiting from the long-stroke design, can reproduce the bass with the frequency down to 40Hz. The powerful bass amplifier can generate output power up to 70 watts (RMS). The flared bass reflex port is calibrated to make the bass more powerful. Start a concert album, your favorite game or a historical movie, to feel the warmth or rocking of deep bass.
