REL Acoustics, the renowned British manufacturer celebrated for its high-performance subwoofers, has launched a groundbreaking new category with the Planar series. Designed specifically for contemporary living spaces, these ultra-slim, wall-mountable subwoofers deliver deep, impactful bass without the traditional bulky enclosures that dominate room layouts.
A New Approach to Subwoofer Design
The Planar series addresses a common challenge in high-end audio and home theater setups: integrating powerful low-frequency performance into minimalist or space-conscious environments. Measuring just 5.7 inches (14.5 cm) deep, the Planar models can be mounted directly on walls or placed discreetly, offering flexibility that traditional floor-standing subs cannot match.
Both models incorporate a hybrid driver configuration with active drivers paired with a rear passive radiator, allowing for efficient bass reproduction in a thin form factor. They also feature built-in wireless connectivity, including the AirShip Direct transmitter, enabling optimal placement for performance without visible cables.
Meet the Models: PL-1 and PL-2
Planar PL-2 (Flagship Model)
- Active driver: Single 8-inch (205mm) FlatPiston long-throw woofer with steel chassis
- Passive radiator: 10-inch (250mm) FibreAlloy cone
- Frequency extension: Down to 24 Hz at -6 dB
- Positioned as the more powerful option for larger rooms or demanding home theater applications.
Planar PL-1
- Active drivers: Dual 6.5-inch (165mm) FibreAlloy cone long-throw woofers with steel chassis
- Passive radiator: 10-inch (250mm) FibreAlloy cone
- Frequency extension: Down to 31 Hz at -6 dB
- Suited for smaller to medium spaces while maintaining REL’s signature musicality and integration.
The series emphasizes versatility, with options for wall mounting, floor placement, or even mobile configurations in some setups. This design philosophy shifts the focus from forcing rooms to accommodate subs to allowing subs to complement the room.
Technology and Performance Focus
REL’s Planar subwoofers maintain the brand’s emphasis on “the art of bass” for both music and movies. The use of advanced materials like FibreAlloy cones and FlatPiston drivers aims to provide speed, control, and authority typically associated with larger REL models. Wireless integration simplifies multi-sub setups, a hallmark of REL’s high-level connection philosophy for seamless blending with main speakers.
Availability is set for May 20, 2026, with pricing to be confirmed closer to launch. Early indications suggest they will target audiophiles and home theater enthusiasts seeking premium performance in elegant, unobtrusive packages.
Industry Context
This release comes as consumer preferences trend toward sleeker, design-forward audio components. While REL’s Reference and Serie lines continue to excel in traditional high-output applications, the Planar series expands the brand’s appeal to modern interiors without compromising on the deep, tactile bass that has defined its reputation.
