Sealed Subwoofers

 Ultra Linear Sealed Subwoofer (ULS)


  Our most musical subwoofer, the ULS MK2 is THE choice for the serious music lover. It also offers the most connectivity options - balanced, unbalanced, and high level inputs. It is also the most spouse friendly - compact, elegant, and unobtrusive. Although not quite as powerful as our VTF-15H MK2, it is also a great sub for home theater applications, especially if you get multiple subs.

Hybrid Subwoofers

 Variable Tuning (VTF) Series


  The VTF series subwoofers are the most adjustable subwoofers in the world. It's like buying 10 or more different subs for the price of one. For a given budget, you can design it to go low, or play loud, or have a ported subwoofer or sealed subwoofer, tight bass or full bass, but not all at the same time. Now with the VTF series, you can have any possible combination. You can operate it in one port open, two ports open, or sealed mode. You can adjust the bass tightness by using our Q control. Whatever your preference and room acoustics, you should be able to find a setting that works great for you.
