100% Positive Reviews
Rated #9 in Subwoofers


Pros: size, sound, controls

Cons: none

Upgraded to this sub from a BIC F12 & the difference is night & day, seriously! This sub provides more clarity & bass extension than the F12 did, music & movies. Is a huge cabinet but works in the corner I have it. Has more controls on the amp than the much cheaper F12 but all ya gotta do is listen to confirm how sweet it sounds!!! Worth every dollar!700

The new VTF-2 MK4 takes advantage of the new technologies we developed for the VTF-15 H -Hybrid tuning variable Q, sealed operating modes – making this one of the most flexible subwoofers we have offered to date, catering to virtually any audiophile’s preferences. With the added Q control and sealed mode options, even higher sound quality is now possible. Harnessing the unique Variable Tuning Frequency port technology (VTF), each port uses the air generated from the long throw woofer to dramatically boost the deeper frequencies. The VTF-2 MK4 succeeds down to a very deep 18 Hz with one port open (in maximum extension mode). The reason for variable tuning is that all subwoofer designs, especially consumer-level subwoofers, involve tradeoffs in design. You cannot have a small subwoofer that goes very low, plays very loud and costs very little. Traditionally, the engineer decides what tradeoff he or she thinks is best for the consumer. The consumer has to take it or leave it. The VTF-2 MK4 changes all that. It allows you, the user, to choose the tradeoff. If you enjoy music that is loud but does not have much deep bass, set the VTF series for maximum output. That way, you get maximum dynamic range with the lowest distortion. If you like music with deep bass, set it for maximum bass extension to reproduce the deep bass accurately. You can even switch between the two modes depending on what you play. That means effectively you get a subwoofer that can play loudly, and can play low, all in one, at a reasonable price!
