Dynamic Balance
Proprietary Polk Audio technology, Dynamic Balance serves to eliminate driver and system resonances that cause distortion. This leads to tight, controlled audio.

Power Port Technology
Reducing turbulence or 'port noise' at the mouth of the bass port, Power Port technology provides deeper, more impactful bass, with less distortion.

Polypropylene Cabinet Design
The durable, mineral-filled cabinet design features molded bracing to reduce internal resonance, while the resistant exterior thrives across seasonal and weather changes, delivering high-quality sound all year round.

Five Year Warranty
Confident in the high-quality make and functionality, this vacuum is backed by a five year manufacturer's warranty, for additional peace of mind.
