1.1"/28 mm Dome Tweeter
Silk dome with polymer laminated (Sonatex™) creates a perfect balance between weight, rigidity, and self-damping. The catenary curvature ensures wide dispersion of the tweeter.Under dome felt damper improves acoustic phase by absorbing reflections from the magnetic structure that bounce through the dome.
High-grade neodymium magnet. Not all magnets of equal size are equal in strength. This high grade (N-52), high-energy magnet provides a high resistance to demagnetization and is over 25% stronger for the same mass than more common lower grade magnets. By utilizing a high-grade magnet, efficiency rises to extraordinary levels resulting in high output but controlled speaker.Main body in fiberglass-filled ABS for superior strength. Acoustic resistance component inside of the ventilation hole helps to control and dampen dome movement resulting in reduced distortion and a linear impedance curve for improved speaker/amplifier coupling.
CNC-machined ultra-low carbon alloy steel pole plate. This type of
manufacturing process ensures perfect flatness so it sits perfectly flush over the magnet without reducing any crucial magnetic flux.The large aluminum copper-clad vented voice coil can handle very high power while reproducing music with extreme realism and high dynamics. The copper clad aluminum wire voice coil is very lightweight and with excellent heat dissipation/capacity.
Deluxe protective stainless-steel grille with perforations calibrated to function as an acoustic lens, guaranteeing the sound emission will be in the on-axis part of the speaker, and also curved to the sides, which is very useful in car installations where speaker placement often results in off-axis listening.CNC-machined aluminum alloy, flush mounted flange.

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.
