KEF
KEF KC62 — Carbon Black
Two powered 6.5-inch Uni-Core force-cancelling drivers
The KEF KC62 is a compact powered subwoofer using the Uni-Core force-cancelling arrangement with two 6.5-inch drivers. Both drivers are powered, working in opposition to reduce unwanted cabinet vibration rather than relying on a passive radiator. Two Class D amplifier channels supply a combined 1,000W RMS. KEF publishes a frequency response of 11Hz to 200Hz within plus or minus 3dB; this is a manufacturer specification, not a promise of the same output at every frequency or in every room. RCA line-level and speaker-level inputs offer installation options, and RCA outputs include adjustable high-pass filtering. Five placement EQ settings help accommodate positions such as a wall, corner or cabinet. The optional KW1 adapter enables a wireless audio connection but is not included. The subwoofer still requires mains power. This listing supplies one Carbon Black KC62 without main speakers.
REL
REL T/9x — Gloss Black
Front-firing 10-inch active driver and down-firing 10-inch passive radiator
The REL T/9x is a powered subwoofer for music and home cinema systems, pairing a front-firing 10-inch active driver with a down-firing 10-inch passive radiator. The passive radiator is not a second powered driver. Its Class A/B amplifier is rated at 300W RMS, and REL specifies low-frequency extension to 27Hz at minus 6dB rather than a complete response range at plus or minus 3dB. High-level Neutrik Speakon, low-level RCA and a dedicated LFE RCA input provide different installation routes. Independent LFE adjustment allows integration with a cinema system alongside a suitable music connection. The optional Arrow system can carry audio wirelessly, but this accessory is sold separately and the subwoofer still requires mains power. This listing is the standard T/9x in gloss black, not the Special Edition, and supplies one subwoofer without main speakers.
SVS
SVS 3000 Micro R|Evolution — Gloss Black
Two opposing active 9-inch drivers in a sealed cabinet
The SVS 3000 Micro R|Evolution is a compact sealed powered subwoofer with two opposing active 9-inch drivers. Their force-balanced arrangement reduces cabinet movement while both drivers contribute to bass output; neither is a passive radiator. This is the R|Evolution generation, with 1,200W continuous Class D amplification and more than 4,000W peak power, not the original 3000 Micro model. Its published frequency response is 20Hz to 230Hz within plus or minus 3dB. RCA and balanced XLR inputs support connection to suitable audio systems. An onboard display and the SVS control app provide adjustments including level, low-pass filtering, phase and equalisation. App control does not make the audio connection wireless. The optional SoundPath Wireless Audio Adapter is a separate accessory, powered from the USB connection. The subwoofer requires mains power and is supplied as one unit, without main speakers.
REL
REL T/7x Gloss Black Active Subwoofer
Single powered subwoofer
The REL T/7x is a single active subwoofer finished in gloss black. It combines an eight-inch front-firing FibreAlloy active driver with a ten-inch down-firing passive radiator and a 200-watt RMS Class A/B amplifier. The radiator is not a second powered bass driver, so describing this as two independently driven woofers would be incorrect. High-level Neutrik Speakon, RCA low-level and dedicated RCA .1/LFE inputs allow integration with suitable stereo and home-cinema equipment. This is the T/7x model rather than the smaller T/5x or larger T/9x. The listing is for one subwoofer only. Front views with and without the grille, the rear connection panel and the underside are retained for inspection. Wireless operation needs additional compatible transmission equipment and is not included here. Follow the manufacturer’s guidance for safe high-level wiring and initial level adjustment.
SVS
SVS PB-1000 Pro Black Ash Active Subwoofer
Single ported active subwoofer
The SVS PB-1000 Pro is a single powered subwoofer with a Black Ash cabinet finish. Its ported enclosure contains a twelve-inch high-excursion driver driven by a Sledge amplifier rated at 325 watts RMS. The manufacturer’s higher peak-power figure is not a continuous output rating and should not replace the RMS specification. This is the PB-1000 Pro ported model, not the sealed SB-1000 Pro or the older PB-1000. RCA inputs support line-level and LFE connections, while the compatible SVS app provides control of settings from a supported mobile device. App communication is for setup and control, not Bluetooth music streaming. The listing supplies one subwoofer, with clean grille-on and grille-off product views and a rear-control detail. Phones, tablets and furnished-room equipment from donor gallery scenes are not included.
Sonos
Sonos Sub 4 Wireless Subwoofer – Black
Dual force-cancelling elliptical woofers
The Sonos Sub 4 adds low-frequency output to a compatible Sonos music or home-cinema system. Two inward-facing elliptical woofers operate in a force-cancelling arrangement designed to reduce cabinet vibration, while dual Class-D amplifiers drive the speakers inside a ported enclosure. Setup and system pairing take place through the Sonos app over a suitable network. This is not a universal RCA or LFE-input subwoofer for arbitrary amplifiers and receivers, and it needs mains power despite the wireless audio connection. The matte Black cabinet can stand upright or lie on its side, subject to the manufacturer's positioning guidance. Trueplay room tuning is available with supported Sonos equipment and setup; this description does not promise identical phone compatibility in every configuration. The listing contains one Sub 4, not a soundbar, speaker pair or complete surround package.
REL
REL T/5x Gloss Black Active Subwoofer
Single powered subwoofer
The REL T/5x is a single active subwoofer in a gloss black finish. Its compact cabinet uses an eight-inch down-firing FibreAlloy driver and a 125-watt RMS Class A/B amplifier. The amplifier rating belongs to the powered subwoofer and is not a recommended power range for separate passive speakers. Connection options include a high-level Neutrik Speakon input, an RCA low-level input and a dedicated RCA .1/LFE input for home-cinema systems. Unlike the T/7x, this model does not use a separate passive radiator. The listing supplies one T/5x, not a pair of subwoofers or a complete speaker system. Clean views show the front, rear controls and underside driver. Wireless transmission requires additional compatible equipment; it is not built into this listing. Choose connections and placement according to the manufacturer’s setup instructions.
SVS
SVS SB-1000 Pro Sealed Active Subwoofer – Black Ash
12-inch high-excursion driver
The SVS SB-1000 Pro is a sealed active subwoofer with a 12-inch high-excursion driver and a Sledge amplifier rated at 325 W RMS. SVS separately specifies more than 820 W peak output; the peak figure must not be presented as continuous power. Its sealed enclosure has no bass-reflex port, and the manufacturer states low-frequency extension to 20 Hz. The SVS Subwoofer Control app provides access to volume, equalisation, low-pass filter and phase adjustments, helping the subwoofer integrate with the rest of a music or home-cinema system. Bluetooth connects the app for control rather than streaming music directly to the subwoofer. This listing is the Pro version in Black Ash, not the older SB-1000 Classic or a different gloss finish. It is one subwoofer and requires appropriate audio connections and mains power; other speakers and source equipment are separate.
Sennheiser
Sennheiser AMBEO Sub / SW02 — Black
One long-throw 8-inch cellulose-cone woofer
The Sennheiser AMBEO Sub is a powered home cinema subwoofer with a long-throw 8-inch cellulose-cone driver and 350W RMS Class D amplification. It is an add-on bass speaker, not a complete soundbar system or a standalone Bluetooth music speaker. Compatible AMBEO Soundbar Plus and Mini models can pair with it wirelessly, while an AMBEO Soundbar Max requires an RCA audio cable from its subwoofer output. A mono RCA input also provides a wired connection option with suitable equipment. The wireless connection carries audio only: the subwoofer still needs a mains socket. The manufacturer's frequency response is 27Hz to 80Hz at minus 3dB. Room calibration through the compatible AMBEO system helps integrate bass with the main bar. This listing is for one subwoofer only; a soundbar and any additional subwoofers are separate purchases.
Sonos
Sonos Sub Mini — Black, Single
Compact sealed Sonos subwoofer
The Sonos Sub Mini is a mains-powered wireless subwoofer finished in matte black, designed to add low-frequency output to a compatible Sonos system. It is not a standalone music speaker and must be paired with an amplified non-portable Sonos product. Two inward-facing 6-inch woofers work within a sealed cabinet, using a force-cancelling arrangement to reduce unwanted cabinet vibration. Sonos specifies a frequency response reaching as low as 25 Hz, rather than a guaranteed result in every room. The compact cylindrical enclosure can be positioned upright without the footprint of the larger Sonos Sub models. Wi-Fi links it to the paired system, and an Ethernet port supports a wired network connection where appropriate. It still requires a nearby electrical socket: wireless audio does not mean battery power. Trueplay tuning uses a supported iOS device to adapt the connected system to the room. There is no general-purpose analogue subwoofer input or Bluetooth music playback. This listing is for one black Sub Mini, with compatible soundbars or speakers purchased separately.
