Description
Highlights
An authentic 3-way coax capable of reproducing a wide frequency spectrum. The DCX 690.3 car audio coaxials uses an oversized magnetic group, TPU (Thermoplastic polyurethane) surround, a 60 mm diameter midrange and a PEI dome tweeter. The result is linearity, wide dispersion and extra-ordinary efficiency not found in traditional coax components. An involving, emotional sound, even at high SPL levels.
Features
- Large motor assembly for mobile voice coil control.
- Pure copper voice coil, wound on conex former, for maximum lightness.
- Water-repellent treated paper cone.
- TPU surround, for wide excursion and resonance damping.
- 60 mm paper tweeter with ferrite magnet.
- Supertweeter with PEI dome, for compactness and energy at high frequencies.
- DIN size basket protected by abrasion-proof dust paint.
- Tin-plated, high current terminals.
- Silver-plated lead wires for maximum reliability and conductivity.
- Butyl rubber protective cover, against crashes and abrasions.
- Epoxy glue for basket and motor system provides perfect coupling.
- Low carbon content plates for maximum magnetic permeability and high heat dissipation
