"tight and tuneful."
(Doug Schneider,

The NSMT EXP subwoofer is an audiophile subwoofer with the speed and accuracy to keep pace with with the best small  minimonitors and the power to play in theater systems. While many subwoofer manufacturers boast mega wattage subwoofer amplifiers, the quality of the subwoofer depends mainly on the design of the subwoofer itself and the real power of the amplifier depends on its design and power supply. The EXP bears this out. It is one of a very few subwoofers that is fast enough to keep pace with very small minimonitors and the bass is exquisite. Not the one note samba delivered by most subwoofers.
The EXP is a potent, compact, self- powered subwoofer system that is designed for use in high-end music and home theater systems. It uses a custom long-throw 6.5 inch woofer that is virtually indestructible and a band pass cabinet design to produce fast, accurate bass response.
The cabinet which is finished in fabric and painted surfaces is a new design based on a unique production method developed by NSMT. The driver is mounted in a sealed acoustic suspension sub-enclosure and fires into a sub-enclosure that is vented to shape the response. The design produces faster, more coherent, and more extended bass response and allows the subwoofer to be placed close to walls.
Magnetic shielding, an innovative band pass design, combined with a gutsy full-featured amplifier allows the EXP to provide an exceptional level of performance and flexibility.

The Model EXP is now finished with a beautiful certified environmentally-friendly finish and the inside panels are sealed to prevent any hazardous off-gassing that can occur from plywooods and MDFs used to make loudspeakers, at no additional cost.
Reviewer's and Customers Comments
"The quality of the bass that the EXP delivers is just like that of the 5 and 10S -- tight and tuneful."
(Doug Schneider,

"The [EXP] compact powered sub allowed me to play rock and pop music at any reasonable volume, with lots of both mid-bass oomph and low end grunt (these are NOT words I associate with small satellite-sub systems). To be sure, there are lots of similarly sized systems out there for those who must hide their speakers from the light of day, but I know of no other that delivers the musical goods at this price range, and with such good looks (if you decide to allow them to peak out from the background).
