Lord of Bass LB12 12″ Subwoofer 750 Watts RMS

SKU N/A Category Tag



The LB Series subwoofers produces deep and clean low-frequency reproduction with minimal distortion at high output levels. Designed from the ground up for output, performance, and reliability. With one goal in mind to produce high end and all-around performance in a single package. Offering an optimized balance of performance and sound quality the LB Series subwoofer line allows users to have the best of both worlds when it comes to sound quality and heart pounding bass.

 When designing the LB Series we began with a FEA optimized motor structure that allows it to work well in both sealed and ported cabinets. LB Series drivers utilizes a very rigid pressed pulp cone to ensure piston motion at high levels for reduced distortion. The LB series offers extremely low mechanical losses which allows for great performance in low volume or extreme dynamic situations. With an 18mm of linear, one-way Xmax enables it to move extreme amounts of air for hitting the lowest notes with maximum output.
