We're asking you to recall your last encounter with the awe-inspiring power of thunder; how its enormous natural presence is able to translate the experience of low frequency sound into a shock wave. The PLW215 II will help you to re-live the air-bending effect of Mother Nature's own subwoofer within your listening room. Twin 15” C-CAM drivers, triple-suspended for a full 4cm of excursion and individually powered by DSP-controlled amplifiers, will deliver clean frequencies down to 16Hz. At this level, bass arrives with a percussive impact that you feel from head to toe, seamlessly extending even the PL500 II to deliver breath-taking audio resolution beyond the limits of your audible range, but with a physical dimension that absorbs the senses. Put simply, it's the sound of nature, vividly re-created.
