NZXT AP-SUB80-US Relay PC Gaming Subwoofer - Powerful Bass

The NZXT AP-SUB80-US Relay Subwoofer is purpose-built to complete the low-frequency picture for desktop gaming and media listening setups — particularly within NZXT's own Relay speaker system. Its 6.5-inch down-firing driver and 140W amplifier are specified to deliver the kind of bass weight that compact desktop satellites physically cannot reproduce: the low rumble of a game environment, the kick drum decay in a soundtrack, the subsonic pressure of cinematic effects. The MDF enclosure addresses a real engineering consideration at this size — cabinet resonance is one of the primary ways that budget subwoofers introduce distortion into the bass register, and the denser material construction keeps the cabinet acoustically inert while the driver does its work.

The control set is practical rather than deep: a crossover knob and phase control give you the two most essential tuning levers for blending a subwoofer into an existing speaker setup. These aren't found on every product at this price point, and their presence reflects a design intent that expects users to actually position and tune the unit rather than plug and accept a factory preset. The under-desk form factor fits comfortably in the standard desktop workflow — out of sightlines, accessible for adjustment, close enough to the listening position that bass propagation timing is manageable. For NZXT Relay system owners, it's the designed completion of a matched system; for those outside that ecosystem, RCA input compatibility requires a source with a dedicated subwoofer output.
