Sealed Subwoofers

 Ultra Linear Sealed Subwoofer (ULS)


  Our most musical subwoofer, the ULS is THE choice for the serious music lover. It also offers the most connectivity options - balanced, unbalanced, wireless, and high level inputs. It is also the most spouse friendly - compact, elegant, and unobtrusive. Although not quite as powerful as out VTF-15H, 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.

 Mid-bass Modules


  Location location location. The best location for mid bass punch is usually not the best location for deep bass. Also, by bi-amping the bass, you gain a lot of headroom. The MBM concept allows you to place the MBM in the location best for mid bass, and the true subwoofer (e.g., VTF-15H, or the ULS) in a location for optimal deep bass reproduction. This approach frequently gives you 10 - 20 dB more headroom compared to placing the true sub in a sub-optimal location. A must for those who demands hit in the chest mid bass punch and wall shaking low bass. Can be operated in sealed or ported modes.
