ULS-15
More views: 
HSU Research is proud to introduce the ULS-15, an ultra low distortion subwoofer that extends down to 10 Hz in most rooms. Besides outstanding performance, it is the most spouse friendly sub we've ever offered, with wireless connection, beautiful finish, and compact size.
It is the first high end subwoofer with wireless connection. This makes it so much easier to optimally place the subwoofer without ugly wires or the high cost of running in-wall wires to the optimal location.
For the truly high end folks, you can also run balanced signal to the subwoofer. The ultra low distortion, super deep bass extension, and balanced inputs make it ideally suitable for recording studios.
The ULS-15 features a woofer with patented super linear motor. The motor force is linear within 2% over an ultra wide +/- 20 mm. In contrast, most woofers with Xmax of +/- 30 mm will have the motor force within 2% over 5 mm or less. It also has a butyl rubber foam surround. Butyl rubber foam has the longevity of solid butyl rubber without the weight penalty. Triple shorting rings mean virtually non-existent flux modulation distortion.
Industry Reviews
"The ULS-15 is the latest in a long line of excellent subwoofers from Hsu Research. It produces low frequency output, with superb transient response. I’d particularly recommend it for anyone using a sub in a critical music listening environment, and would not hesitate to put one into my home recording rig."
