A sound experience that you can hear and feel
The HELIX PR W165 premium woofer is an example of absolute excellence within the PURE speaker lineup. It delivers unparalleled sound quality that you can hear but also feel. The stiff Mica-Paper composite cone ensures not only a punchy kickbass but also delivers a balanced midrange reproduction that brings your music to life.
