REL Acoustics Planar PL-1

Overview

The REL Acoustics Planar PL-1 is the entry point into REL's newest Planar series, a fresh design language that carries forward the brand's core philosophy of building subwoofers for music first. Like every REL, the PL-1 is engineered to augment a full-range system rather than simply pump low-frequency effects. Its signature high-level Speakon connection takes signal directly from your main amplifier's speaker terminals, so the subwoofer inherits the exact character, timing and voicing of the amplifier driving your loudspeakers. The result is a bass foundation that arrives in perfect step with the mains, filling in the bottom octaves you cannot hear from stand mounts or slim floorstanders.

Beyond the high-level input, the PL-1 offers a separate .1/LFE input for home theater duty and a low-level RCA option, letting a single sub serve both music and movie systems. On-board amplification, a continuously variable crossover, gain and phase controls let you dial the sub precisely into your room and to your main speakers. REL wireless options and REL cables allow either a cable-free or reference-grade wired connection depending on how you want to place the unit.

The PL-1 is ideal for the listener building a high-value two-channel or hybrid theater system who wants genuine REL musicality and clean room placement without stepping into the larger reference models. It pairs naturally with stand mount and compact floorstanding speakers, and like all RELs it can be run as a stereo pair or stacked for greater output and even more precise imaging.

How the Planar PL-1 Compares

REL Planar PL-1 vs REL Planar PL-2

The PL-2 sits one step up in the same new Planar range and offers more output and greater low-frequency authority for larger rooms or more demanding systems. The PL-1 shares the Planar design goals and musical high-level voicing while suiting more moderate spaces and compact main speakers. Choose the PL-2 when the room is large or you want extra headroom in the bottom octaves. See the REL Planar PL-2.

REL Planar PL-1 vs REL T/9x

The T/9x is REL's music-focused mid range model built around a 10 inch driver and forward and down firing arrangement. It shares the same high-level Speakon philosophy as the PL-1 but represents the established T/x design language rather than the new Planar platform. Consider the T/9x if you want a proven mid range music sub, and the PL-1 if you are drawn to REL's newest design approach. See the REL T/9x.

REL Planar PL-1 vs REL S/550

The S/550 belongs to REL's high performance S line and targets listeners wanting substantial output with fast, articulate bass for both music and cinema. The PL-1 focuses on integrating cleanly and musically with compact and mid size systems from the new Planar range. Step to the S/550 when you need more scale and slam in a larger space. See the REL S/550.

Recommended System Pairings

A subwoofer adds to an existing system, so these picks are main speakers, an amplifier and REL connection accessories that let the PL-1 do its job. Every choice supports REL's high-level, music first design.

• Spendor Classic 4/5 This refined two way stand mount images beautifully but naturally rolls off in the low bass, so the PL-1 fills in the foundation below it for full range scale. A classic REL plus stand mount pairing.
• LEAK Sandwich 250 A characterful stand mount that benefits from added low-end weight and room energizing bass that the PL-1 provides while preserving the speaker's midrange purity.
• Audiolab 9000A Integrated Amplifier A capable integrated to drive your mains, and its speaker terminals feed the PL-1's high-level Speakon so the sub follows the amplifier's exact character and timing.
• REL AirShip II Wireless For clean, cable-free placement the AirShip II wireless system lets you position the PL-1 optimally in the room without running a long cable across the floor.
• REL Bassline Blue High Level Cable An upgraded high-level connection cable that improves the wired Speakon link between your amplifier and the PL-1 for the cleanest possible blend.
