Subwoofers — Rel Acoustics Planar PL-2

The Planar PL-2 is a slim powered subwoofer from REL Acoustics, sitting above the Planar PL-1 with somewhat greater scale and substantially more internal amplification while sharing the same remarkably thin cabinet depth. The Planar PL-2 brings REL's engineering to a more capable slim-profile bass-reinforcement tier.

Key specs that matter

Rated response reaches down to a deep 24Hz, extending meaningfully lower than the Planar PL-1. Internal amplification delivers a substantial 550W - considerably more than the PL-1's 300W. At 65.0 x 48.0 x 14.4cm and 20.5kg, the Planar PL-2 shares the same slim 14.4cm depth as the PL-1 while offering greater width.

Sound and use context

Expect more authoritative bass reinforcement reflecting the substantial 550W amplification and deeper 24Hz reach, delivered from the same discreet slim-profile cabinet depth as the smaller PL-1.

Pairing

As a self-powered subwoofer, the Planar PL-2 connects to a preamplifier, integrated amplifier or AV receiver's subwoofer output directly, its slim profile suiting discreet wall placement.

Alternatives

REL Acoustics' own Planar PL-1 sits below this model as a more compact, lower-power alternative sharing the same slim depth, worth considering instead if the PL-2's additional scale exceeds what a specific room requires.
