Designed to work in close relationship with the wall behind it, Planar uses boundary effect coupling to produce deep, room-filling bass and exceptional scale from an ultra-thin form that occupies little-to-no floor space. PL-2 redefines what is acoustically achievable from a wall-hugging form factor, bringing REL’s heritage of deep, powerful bass to rooms previously beyond its reach. Its boundary-coupling philosophy is a genuine engineering innovation — turning the room’s architecture into an active participant in bass reproduction.\u003c\/span\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-outline-level: 3;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eDeep Bass in Minimal Space — REL Performance in Ultra-Thin Form\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;\"\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eTraditional subwoofers often require significant floor space to produce deep, impactful bass. PL-2 adopts a distinct approach. By working in close relationship with the wall behind it, Planar uses boundary effect coupling to transform the wall into part of the acoustic system, delivering bass into the room with scale, depth, and authority that feels far larger than the product itself. Whether mounted directly on-wall or placed close to the wall using the optional Cart, PL-2 provides powerful, immersive performance for modern rooms and open living spaces where traditional subwoofers fail to integrate gracefully. The boundary effect approach is not a limitation of the design — it is the core acoustic principle upon which the entire PL-2 system is built. The result is a subwoofer that rewards thoughtful placement with bass performance that rivals far larger and more conventional designs.\u003c\/span\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-outline-level: 3;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eEngineered for Contemporary Living Spaces\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;\"\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003ePlanar PL-2 was engineered to deliver true REL performance from an ultra-thin form that blends naturally into modern spaces. Its slim proportions, flowing radiused edges, and deep lacquer finishes enable it to occupy spaces where traditional subwoofers often seem intrusive. Every detail was meticulously considered, from the recessed controls and concealed cable management to the optional hardwood grille upgrades that further enhance its architectural presence. Available in black or white lacquer finishes, Planar PL-2 merges elegant industrial design with purposeful engineering, producing a subwoofer designed not only to sound extraordinary, but to live beautifully within the room itself. To help control the interaction between the cabinet and the wall, Planar employs REL’s VIMAR (Vibration Isolation Material and Resonance Control) system. Integrated into the mounting brackets, VIMAR minimises the transfer of unwanted energy into the wall while maintaining the speed and integrity of the bass. The result is purer, more precise low-frequency performance. The optional hardwood grille upgrade transforms the PL-2 into a genuine piece of furniture-grade cabinetry that enhances rather than disrupts the room’s aesthetic. VIMAR’s vibration management is an often-overlooked but critical engineering detail that separates the PL-2’s wall-mounted performance from simpler, less refined competitors.\u003c\/span\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-outline-level: 3;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eFlat Piston Driver for Massive Scale\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;\"\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eCreated exclusively for Planar, PL-2’s new 8″ Flat Piston driver was engineered to deliver exceptional output from an ultra-thin cabinet. Generating deep, powerful bass from a driver barely 80mm deep required a completely new approach to excursion, rigidity, and control. The result is fast, dynamic bass that extends to 27Hz, reaching more than an octave below the fundamental range of many acoustic instruments while providing the scale and authority demanded from far larger subwoofers. Achieving 27Hz bass extension from a driver just 80mm deep represents a genuine engineering breakthrough that required months of prototyping and acoustic refinement. The Flat Piston’s exceptional pistonic behaviour minimises unwanted cone breakup, ensuring that the bass remains clean and articulate even at high output levels.\u003c\/span\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-outline-level: 3;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eBoundary-Coupled Passive Radiator Bass\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;\"\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eA precisely tuned 10″ long-stroke passive radiator, featuring a lightweight paper cone reinforced with a rigid aluminium center cap, fires toward the wall behind Planar, using boundary effect coupling to reinforce and extend low-frequency output. Working in close relationship with the wall surface, PL-2 transforms the wall into part of the acoustic system, delivering deep, room-filling bass and exceptional scale from an ultra-thin form. The result is bass that feels natural, expansive, and far larger than the cabinet itself implies. The long-stroke passive radiator’s lightweight cone moves with exceptional speed, ensuring that the boundary-coupled bass remains as fast and articulate as it is deep. This two-pronged low-frequency strategy — active driver plus passive radiator working in concert with the wall — creates a bass presentation of unusual depth and authority.\u003c\/span\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-outline-level: 3;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eEffortless Power and Proven Long-Term Reliability\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;\"\u003e\u003cspan style=\"font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; color: #dcdada; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003ePL-2 is driven by a 550-watt Pure Class D amplifier engineered to provide effortless dynamics and exceptional control from an ultra-thin platform.
