Good things really do come in small packages — and then they hit you with 129 dB of bass. The RCF SUB 808-AS is a compact, low-profile active subwoofer that has absolutely no interest in being the biggest box in the room. What it lacks in size, it makes up for in sheer output, packing two vented 8-inch neodymium woofers and a 2000W Class-D amplifier into a cabinet that slides under a stage, tucks along a wall, and still delivers the kind of low-end that gets felt in the chest.
Built from Baltic birch plywood, finished in weatherproof polyurea, and loaded with RDNet networked management, the SUB 808-AS is a serious touring subwoofer that just happens to travel light.
Two heads are better than one — especially when both of them are 8-inch neodymium woofers. The SUB 808-AS runs a dedicated Class-D amplifier channel to each driver, meaning every watt of that 2000W peak output goes directly where it needs to go. The result is a compact active subwoofer that hits harder than its dimensions suggest, covering a 40–400 Hz operating range with authority.
RCF didn't just put drivers and power in a box — they engineered the whole signal path. High-end 96 kHz/32-bit floating-point AD/DA conversion and onboard DSP keep the audio clean at any output level, while Bass Motion Control (BMC) handles woofer excursion management in a way that most manufacturers don't bother with. The short version: the bass stays tight even when you're pushing it.
The Baltic birch plywood cabinet comes internally reinforced, wrapped in weatherproof polyurea coating, and topped with a powder-coated steel grille backed by acoustically transparent foam for dust and humidity protection. At 44.09 lbs. with a side handle and a low-profile 9.59-inch height, it moves faster between venues than most gear twice its size.
The RCF SUB 808-AS proves that you don't need a giant box to move air seriously. Its dual 8-inch design, 2000W Class-D power, BMC excursion management, and RDNet integration put it in a category where compact, networked, and high-output actually coexist. Run it standalone, stack it into a cardioid array, or pair it with the KX 515-A for a full-range system that fits in a hatchback — the SUB 808-AS adapts without compromising.

RCF designed the SUB 808-AS as the dedicated low-frequency partner for the KX 515-A, with matched phase and frequency compatibility for a cohesive full-range system. It also works well with other full-range tops that benefit from extended low-end reinforcement down to 40 Hz.
