A category dedicated to subwoofers, specialized loudspeakers designed to reproduce very low bass and sub-bass audio frequencies.
Subwoofers are specialized loudspeaker components explicitly engineered to reproduce very low-pitched audio frequencies, commonly known as bass and sub-bass. Whether implemented into a home theater setup, a computer's audio system, or a custom car audio installation, subwoofers provide the depth and physical rumble that standard full-range speakers simply cannot produce. This category features a collection of user manuals, installation guides, wiring diagrams, and troubleshooting documentation for a wide variety of subwoofers across multiple manufacturers.

Common questions about manuals, registration, and support for this brand.
An active (or powered) subwoofer features its own built-in amplifier and requires a direct power outlet connection. A passive subwoofer does not have a built-in amplifier and must be powered by an external stereo receiver or amplifier.
Most powered subwoofers are connected using a single RCA cable. Plug one end of the RCA cable into the 'Subwoofer Out' or 'LFE' port on the receiver, and the other end into the 'LFE In' or 'Line In' on the back of the subwoofer.
While bass is omnidirectional, placing a subwoofer in a room corner usually produces the loudest response. However, to find the smoothest and most even bass sound, audiophiles often use the 'subwoofer crawl' technique to locate the acoustical sweet spot.
A standard and generally recommended crossover frequency for a typical home theater setup is 80Hz. This means the subwoofer handles all frequencies below 80Hz, allowing your main speakers to focus on mid and high frequencies.
