QEX-1020 - CDT Audio 10" 500W RMS Cast High-Power Small Enclosure Subwoofer

These engineering masterpieces simultaneously deal with the need to move large amounts of air necessary to overcome the 70+ db. of bass masking road noise in the moving automotive interior, while accurately responding to the delicate changes in the harmonic structure of the music. All while doing so within an acoustic suspension enclosure that won’t waste the consumer's valuable trunk space.

Their depth, rugged, non-ferrous cast baskets are coupled with a suspension system which allows the cone and voice coil assembly to move as an exact analog of the electrical signal, while at the same time controlling the limits of excursion and eliminating extraneous motion. Real butyl rubber, though more expensive than conventional materials, has been chosen for the outer surround; it provides far superior control, longer life and excellent damping of the cone edge, and even lowers distortion at the limits of excursion. Superior-pole vented motor structures propel sturdy 2.5" aluminum voice coils for rapid heat dissipation, eliminating the possibility of dynamic compression and lowering of output.
