SPL12.1 12" Inch 30cm 4Ohm SVC Subwoofer 650w RMS


World RRP: £59.99


Product code: SPL12.1.4

Product description

The most popular size for a car subwoofer at present, the 12″ Bassface woofer is a clear winner. Phenomenal low end performance whilst retaining sledgehammer drum transients – the combination of a large cone and relatively lightweight 2 inch voice coil construction is kept in check by our double roll surround suspension system. Designed to run in enclosures from 0.8 to 1.8 cubic feet, these aren’t going to take up too much space either.

Prototyping was undertaken in the USA in Q1 2012 following a meeting in Hong Kong between us and several factories who had tender on the project. The winning factory has facilites both in the US and the far east and a great deal of experience with this kind of lightweight, lower cost unit. We worked hard to extract every ounce of performance available at the price point. The design has proved to be ubiquitous and highly reliable.
