REL Acoustics PLANAR PL-1 WHITE Planar Dual 6.5-Inch Powered Subwoofer in Gloss White Lacquer (Each)
The REL Acoustics PLANAR PL-1 WHITE is an ultra-thin powered subwoofer in the Planar series, combining dual 6.5 in active drivers, a 10 in rear passive radiator and a built-in 300-watt RMS Pure Class D amplifier. Designed for on-wall or near-wall placement, it pairs Gloss White Lacquer with included Airship Direct wireless and low-frequency extension rated at -6 dB at 31 Hz in room. The wall-assisted design adds bass support for two-channel music and compact home theaters where a conventional subwoofer would occupy too much space.
Key Features
Designed to Fit Naturally
Flowing cabinet edges, recessed controls and concealed cabling give this slim-profile subwoofer an unobtrusive presence in a finished living space. A cloth grille is supplied; the premium wood grille and Planar Cart are optional upgrades and are not included.
Dual 6.5 in Drivers and a 10 in Passive Radiator
Long-throw FibreAlloy cones and steel chassis equip both front-firing woofers, with a FibreAlloy cone and steel chassis also used for the rear radiator. Positioned toward the wall, that passive radiator uses the adjacent surface to reinforce low frequencies, making wall proximity part of the bass design.
300 Watts RMS of Pure Class D Power
The powered design needs no separate subwoofer amplifier, supplying controlled bass for music and film soundtracks through Pure Class D circuitry. Fully Electronic Set Safe, D.C. fault and output-short protection are built in.
Included Airship Direct Wireless
The included Airship Direct system has a factory-paired receiver concealed in the rear compartment. It avoids long signal-cable runs and needs no app or software update for setup, but AC power remains necessary and the transmitter connects to your audio system.
PerfectFilter and Flexible Stereo and Theater Inputs
The high-level Neutrik SpeakOn connection lets bass follow the main speakers' signal, while low-level RCA and LFE RCA inputs provide additional stereo and theater connection options. Analog input filtering and PerfectFilter circuitry are designed to integrate bass with the main speakers' timing. The supplied 1.5 m high-level cable is intended for the Airship Direct transmitter, and two RCA cables are also included.
VIMAR-Isolated On-Wall Mounting
VIMAR mounting-bracket isolation helps reduce unwanted vibration transfer into the wall. The supplied template, brackets, hardware and right-angle power cord support on-wall mounting; allow an additional 1.5 in of depth for the bracket. Installation requires suitable wall anchoring, and installer tools and consumables are not all supplied.
For Smaller-to-Medium Music and Theater Rooms
Intended for smaller-to-medium rooms, the design complements stand-mounted speakers and smaller floorstanders where proportionate bass and unobtrusive integration matter. Use it for two-channel music or compact home theater; a single subwoofer is supplied. Multiple units may improve coverage, and stereo subwoofer operation requires two matching units.

Footnotes:
Measured performance figures are based on manufacturer testing under specific conditions and vary with the room, settings and use.
Never ceiling-mount this subwoofer. Sheetrock installations require structural stud anchoring; masonry installations require appropriate inserts. Both mounting brackets and their gaskets must be used. Two installers are recommended, with professional assistance for plaster. Consult the owner's manual and a qualified installer for mounting instructions.
For optional-cart or freestanding use, install the included anti-fall restraint as instructed to reduce accidental tipping risk.
