HELIX PURE R-series: Flawless sound, pure excellence

HELIX PURE transcends beyond mere music. It’s an audiovisual journey, dedicated to uncompromising sound quality and uniqueness, designed for discerning audiophiles and individualists who refuse to make compromises in their daily life. The PURE R-Series represents the pinnacle of our PURE speakers, combining their essential features to perfection: uncompromising sound quality, high-quality materials and unparalleled aesthetics.

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. To achieve optimal impulse response, it utilizes an exceptionally powerful magnet system while the rigid aluminum diecast basket with streamlined, low-turbulence design guarantees ideal impulse fidelity. Furthermore, additional ventilation holes in the basket enhance coil cooling and enable impressive power handling. Always included: HELIX grilles for the ideal protection of the cones.
