Product Information

Bass You Can Feel

SUB8 is a sealed box front-firing subwoofer offering 250W of powerful bass extension, perfect for music or home theater. A precise low-pass filter makes SUB8 a perfect match with any Kanto speaker, allowing you to dial in the perfect cutoff frequency. Its 8” paper cone driver enables true sub-bass reproduction with low-end that has real weight. Phase adjustment, power saving auto-off and full L/R line level input round out this high-performance package.


Every space is different. Precise dials for volume and cut-off frequency offer exacting, responsive control that lets you shape your bass to fit the unique character of your room.

Stereo Inputs

Although designed to be a perfect match with Kanto speakers, SUB8 features stereo inputs allowing use with any source. Anything from vintage stereo receivers to high-end amplifiers with stereo sub output can be connected, so you don’t have to sacrifice quality for convenience.


Solid rubber feet keep SUB8 firmly planted on any surface. Isolating the housing from the surrounding environment allows for unmatched clarity and separation from lower-mid frequencies, and reduces vibration.

Acoustic MDF

SUB8’s acoustic MDF enclosure is engineered to reduce undesired resonance and reverberation inside the box, providing clean, uncolored sound.


SUB8 is available in black and white with a smooth matte finish.


SUB8 features a specially designed grille that protects the driver from impact and dust while allowing sound to travel through with minimal diffraction.
