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.

FAQs
Q: Will these speakers fit my car?

A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.

Q: Do I need an amplifier to run these speakers?

A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.

Q: What is the difference between coaxial and component speakers?

A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.

Q: Do these come as a pair?

A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.

Q: Can CEN fit these speakers for me?

A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
