Lord of Bass LB12 12″ Subwoofer 750 Watts RMS

Lord of Bass LB12 12″ Subwoofer 750 Watts RMS

The Lord of Bass LB12 12″ Subwoofer delivers deep, clean low-frequency reproduction with minimal distortion, even at high output levels. Built from the ground up with a focus on output, performance, and reliability, these subwoofers are engineered to deliver high-end sound and all-around performance in a single package. With a carefully optimized balance of sound quality and heart-pounding bass, the LB Series allows users to enjoy the best of both worlds — whether you’re looking for precision or power.

When designing the LB Series, we focused on an FEA-optimized dual stack 180mm ferrite motor structure that ensures exceptional performance in both sealed and ported enclosures. This powerful motor design provides increased magnetic strength, allowing the subwoofer to handle 750W RMS without compromising sound quality. The 2.5″ copper voice coil offers excellent thermal conductivity and responsiveness, while the rigid pressed paper cone ensures piston-like motion during operation, reducing distortion and enhancing low-frequency accuracy.

The LB Series is engineered to perform in dynamic situations with ease. Its dual-layer Nomex spider pack with flat leads ensures superior excursion control, reducing mechanical losses and enabling reliable performance across a wide range of volumes. With 18mm of linear one-way Xmax, the subwoofer can move large amounts of air, delivering powerful output and hitting the lowest notes with clarity and authority. The inclusion of a cast aluminum basket adds structural integrity, improving heat dissipation and ensuring consistent performance, even under extended use.

Whether you’re upgrading your home theater or building a high-performance car audio system, the LB Series Subwoofers are designed to deliver unmatched bass, performance, and reliability. Experience the perfect blend of precision and power with the LB Series.
