8-inch tube subwoofer enclosure

The Nippon tube box holds an eight-inch driver in a ported cylindrical cabinet. It arrives new and ready to install in a vehicle boot or cargo area. The sealed-tube design saves space while adding low-frequency output to a factory or aftermarket system. First listed by the manufacturer in November 2018.

Best for simple bass upgrades

Buyers who want a single, self-contained subwoofer that fits behind a seat or in a spare-wheel well will find this format convenient. Installers who need a specific impedance match, a dual-voice-coil driver or a shallow-mount profile should look at other enclosures.

Eight-inch driver in a ported tube

The enclosure is built around an eight-inch woofer mounted in a bass-reflex tube. That diameter and the ported alignment are the key specifications that determine whether the box matches the amplifier power and the available space in the vehicle.

Questions about this item

Can the 8 inch Nippon tube box share the same amplifier wiring as my existing subwoofer?

Yes, it connects to standard speaker-level inputs so you can run it from the same amp channels without new power cables.

How do I confirm the Nippon 8 inch subwoofer is performing correctly after installation?

Play a bass test tone at moderate volume; the cone should move smoothly and the enclosure should stay vibration-free.

What comes in the box with the Nippon tube subwoofer and what must I buy separately?

The tube enclosure with the 8 inch driver is included; you will need to supply an amplifier, speaker wire and mounting hardware yourself.
