Compact sealed subwoofer

The Kanto SUB8VMB is a sealed powered subwoofer with an 8-inch paper cone woofer and a built-in Class D amplifier rated at 300W. It connects via RCA or 3.55mm AUX inputs and includes an RCA cable for quick setup. The enclosure measures 11.00 inches wide, 11.00 inches deep and 11.90 inches high, making it small enough to sit under a desk.

Suited for near-field listening

This subwoofer suits desktop systems, small living rooms or apartments where a compact sealed design blends with existing Kanto speakers. It is not for buyers who need higher output for large home-theatre spaces, nor for installations that require wireless connectivity or a dedicated LFE input.

Headroom at reference levels

The 300W amplifier and sealed alignment deliver clean output down to 35 Hz with a frequency response extending to 175 kHz. Sensitivity is rated at 88 dB at 4 Ohms nominal impedance. The low-pass filter and phase switch let you match the subwoofer to main speakers, but the single 8-inch driver cannot pressurise a big room to reference cinema levels.

Questions about this item

Does the subwoofer need a separate amplifier to work?

No, it has a built-in 300W Class D amplifier so it only needs mains power and a signal from your system.

Can I connect it to an older stereo that only has speaker-level outputs?

The unit accepts RCA or 3.55mm AUX line-level inputs only; it does not have speaker-level terminals.

How do I confirm the low-pass filter is set correctly after installation?

Play bass-heavy material and adjust the low-pass frequency control until the subwoofer blends smoothly with your main speakers.
