Take an Engage Subwoofer and add it to a solid 18mm MDF trapezoid box and Engage Enclosures add a whole new level to the term 'engaging bass'.
However, Mutant is not content in stopping there. Add a high power class-D amplifier and complete 5m pre-terminated 100% copper wiring kit and you get the engage bass pack - the ulitmate one-box bass solution.
