30W/4558T06
The 30W/4558T06 is the bigger brother of the 26W/4558T06 and is a dedicated automotive 12" sub bass drive unit featuring a rigid anodised Aluminium cone, double magnet with Faraday ring and a vented diecast chassis. Capable of huge output with true depth and accuracy, this is a very 'fast' sounding woofer with superb dynamics. The response is tailored specifically for the automotive environment and with a low Fs of 17Hz, huge peak excursion of 56mm + a peak power of 350 watts this woofer produces prodigious amounts of tight bass that is felt as well as heard.
