About Kanto SUB8 8" 300W Sealed Powered Subwoofer

SUB8 gives you the speed and accuracy that only a sealed subwoofer can deliver. An 8" woofer driven by a 300W amp responds quickly to transients and keeps distortion to a minimum. Its compact size provides full-range sound without sacrificing floor space and a crossover filter and phase control allow for easy integration into any audio system.

Sub8 provides worry-free longevity with its rigid MDF construction, solid rubber feet, metal grill, and durable vinyl finish. With matching aesthetics, sub8 is the perfect companion to any Kanto speaker or wherever else tight bass in a tight space is needed.

Experience the full impact of every song and soundtrack

Sealed Enclosure
Sealed subwoofers react to changes in audio more quickly than vented designs. Every bass note is reproduced accurately with little distortion allowing you to hear pure audio and not the subwoofers' influence on the sound.

Compact Design
At roughly 11" in each direction, sub8 fits under desks or in the smallest of apartments where traditional home theater subwoofers may dominate the space.
