FTW-LTE – Light Heavyweight

We revamped the FTW-LTE to give you just a little bit more of what it is you seek in a high performance subwoofer – more excursion, more power handling, lower distortion.  A slightly larger copper wound voice coil and induction control provides everything you want when hitting the lows without breaking your bank account.

The FTW-LTE will find home in most mid to large sized rooms where multiple units could be employed.  Use the LTE in sealed enclosures or multiple units for Infinite Baffle.

    I built a 10.27 cbft box with 5lbs of polyfil. I am loving this subwoofer. Great bass all around. Does great with movies and music. If you want a subwoofer that doesn’t struggle at anything you throw at it , this is the one 🙂 The best way to describe it is the bass is effortless, clean and controlled.
