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


World RRP: £61.99


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 0.7 to 1.2 cubic feet, these aren’t going to take up too much space either.

Still going strong on the V1. While we have identified areas that can be improved (it is a budget and very cheap woofer) we have taken the position that it performs very well for the money and improvement would add cost. So why change it? 😉 V2 – The V2 if it comes into fruition will be an entirely new product and this will remain.
