Bob's design for a high-pressure (and miniature size) subwoofer was so unique that he got a patent from the U.S. Patent office. The significance of the design is that a physically tiny subwoofer can produce absolutely earth-shaking, sub-sonic bass at high volumes without loss of coherence or tightness. With the Sunfire True Subwoofer, a music and film enthusiast can have real bass in a room that could never support a large, bulky, old-school subwoofer.
The Sunfire True Subwoofer Signature is our flagship model. At 13 inches cubed, the Signature woofer produces mind boggling bass from a box which is a fraction of the size of its competitors. Powered by a special internal Sunfire 2700-watt amplifier using Bob's patented Tracking Downconverter power supply technology, the Sunfire True Subwoofer Signature has no equal.

This is the subwoofer that started
the revolution. At 11 inches cubed, the Sunfire True Subwoofer (now
generation IV) re-defines the term "spouse friendly."
The True Subwoofer Mark IV is small enough to fit into practically
any music or theater system. It's easy to set up and position to
quickly add stunningly high levels of deep and musically accurate
bass to your system.
The True Subwoofer Mark IV incorporates two of Bob Carver's patented
inventions: First is the high-pressure, high-back-emf design which
allows creation of incredible levels of bass energy from an impossibly
small enclosure. Second is Bob’s Tracking Downconverter power
source used to supply the internal 2700-watt amplifier. This subwoofer
has absolutely no performance equal its size.

We took a good
thing and made it, well, smaller. At $995, the Sunfire True Subwoofer
Super Junior fits any room and any budget. Using he same patented
amplifier and speaker technology as it's award winning big brothers,
the True Subwoofer Super Junior packs serious bass into a tiny nine-inch
cube.
The Super Junior is perfect for entry-level systems coupled with AV
receivers or lower-priced AV preamps. Many Sunfire dealers find the
Super Junior woofer matches up very well with bookshelf loudspeakers
and floor standing speakers alike.
The Super Junior’s modest price and
diminutive size also make it ideal in installations not suited for
a single larger sub. Good placement of one woofer provides bass
extension with even dispersion. Two woofers guarantee it.
Modern desktop personal computer systems come loaded with DVD drives,
ultra-high resolution and possibly 16x9 (letterboxed) aspect ratio
monitors. Add in a DSL (or faster connection) to the Internet and
you have a direct pipeline into an unprecedented storehouse of music.
A Sunfire subwoofer can add impact and detail to an amazing desktop
music system, as well as add thunderous realism to PC video games.
