Onkyo Skw-391 bass reflex subwoofer 130 watt 8" passive

Onkyo’s proprietary Super EX.Bass function boosts low-frequency output at two separate points: 40 Hz and 80 Hz. At low volumes, Super EX.Bass creates a deeper, more dynamic bass sound for your music and movies. When the volume is turned up high, the boosted bass automatically returns to normal levels.
