Subwoofers can be hard to hide, but Polk’s CSW 155 becomes virtually invisible after it is installed between wall studs. A paintable grille makes for an even stealthier look. Combined with Polk’s $700 companion SWA500 amplifier, the CSW 155 outputs ultra-low bass to 103.8 dB and low bass to 120.9 dB.
the nitty gritty
- It’s the shallowest driver Polk has engineered.
- Rigid, cast-aluminum basket helps contain resonance.
- Klippel Distortion Analyzer optimizes sound.
