Eton USB 8 AR: 200mm (8 inch) active underseat subwoofer

A 200mm (8 inch) active subwoofer in a closed die-cast aluminium housing with an integrated 160W (2 x 80W) amplifier module. The driver is a specially developed 2 x 2 ohm dual voice coil long excursion unit with a reinforced cone.

Stealth design cooling fins improve thermal performance. Features hi and lo-level inputs, an integrated low pass filter (50–100Hz) and auto turn-on (DC/SIG). Compatible with vehicles fitted with start/stop systems. Includes connection material, mounting feet and a level remote control. Engineered in Germany.

The USB AR series has been fundamentally revised since its launch in 2013. The updated die-cast aluminium housing follows Eton's Stealth design, offering greater rigidity and improved cooling, while the revised driver delivers higher sound pressure. Its compact dimensions make it a practical bass retrofit, particularly in classic cars and camper conversions.
