MBM-12 Mid-bass Module

Double the mid-bass impact


The MBM-12 introduces our new patent pending concept of splitting up the bass frequencies. In most moderately sized rooms, mid-bass is best reproduced near the listener, while deep bass is best reproduced in a far corner. The mid bass module allows one to do optimally position the low frequencies nearby, for maximum impact.

The high direct to reflected sound ratio helps reduce room effects, gives excellent headroom (high SPL with low power since you are right next to the woofer), and low distortion. Low bass, on the other hand, is most efficiently reproduced when placed in a front corner (see figure below).

Just like the VTF concept, a woofer optimized for low bass reproduction is not the best for mid to upper bass reproduction. A heavy cone is best for low bass, but that reduces the mid to upper bass efficiency. The MBM-12 woofer is optimized for mid to upper bass reproduction - a very light cone, low inductance voice coil, and a strong magnet yields extremely quick response with high efficiency. It demonstrates excellent micro-dynamics and an extremely wide dynamic range that no single subwoofer can provide.


Industry Reviews

"One exhibitor, Hsu Research, had a setup that literally stunned me. In the back of the room where I was sitting, right behind my chair, was one of his new designs, called the MBM-12 Mid-Bass Module, that only reproduces the range from 50 to 150 Hz. He had it set for the range of 50 to 80 Hz. Since it is close to the sitting position, it does not have to be turned up very loud, although it has a 350 watt amplifier. The driver is lightweight, so it responds very quickly. The gunfight scene from Open Range was used for the demo, and the gunshots, because of that special woofer (of course, he had his regular subwoofers in there too, for the really low frequencies), sounded as close to real as I have ever heard in a home theater room. The effect stuck with me all afternoon. Anyway, if you ever have the chance to hear this demo at a local home theater show, be sure to sit in on it. Absolutely unbelievable! "
