INTRODUCTION
The 12″ 1800W Active/Powered Subwoofer SUB-12 Pro has more than enough power to power passive speakers, allowing for the perfect complete stereo system. The SUB-12 Pro is “powered,” which means they have amplifiers already built-in. Being a powered speaker, each model has the power to drive two other external speakers for a combined maximum power of 1800 Watts.
SUB-12 Pro is made of with solid plywood with advanced environmental protection polyurethane-based painting which is very dense. We are fencing each cabinet to provide strong ultra-weather ability. With this design, each bass speaker reduces interference and enhances the sound quality.
