7.1-channel Active Studio Subwoofer
Model: KH 870
- 7.1 Channel High Definition Bass Management™ compatible with all formats from mono to 7.1
- Bypassable 4th order 80 Hz active crossover for maximum compatibility with consumer reproduction
- 0 and +10 dB LFE gain and 4-mode LFE processing:
- LFE to subwoofer and left/right
- LFE to subwoofer only up to 80 Hz
The latest amplifier technology and acoustical components have been used to ensure the most accurate sound reproduction possible. Robust drivers, a rock-solid cabinet, and carefully designed ports guarantee a tight, articulate, and distortion-free low frequency reproduction, even at high replay levels. Using the sum output, Plane Wave Bass Array™ (PWBA™) techniques acoustically improves lateral consistency in the listening area. The bass extends down to 18 Hz.
