The next generation of high output (HO) subwoofers is here. They are optimized for reproduction of low bass at high levels with low distortion. We achieved this level of performance by using several patent pending and patented technologies - our bent port technology, turbocharger technology, and the use of a woofer with a patented linear motor.

The lowest bass comes from the port. You need large ports to move lots of low bass without port noise or compression. With the HO, we went to dual 4" ports, which nearly doubles the port size compared to the VTF-3 Mk 2.

Adding the patent pending turbo doubles the port area for extended bass mode, allowing the VTF-3 HO to move as much air as four VTF-3 MK2 models in extended bass mode with the same level of port noise.

The patented linear motor used in the HO has an extremely low distortion over its full operating range. This complements the low distortion, high output low bass afforded by the patent pending bent port and turbo technologies.
