Sunfire TRUE SUB EQ Subwoofer

FREE QED Qontour 6m Sub-woofer cable worth £80

"Never has there been a subwoofer that could pump out such prodigious deep bass at -levels capable of rattling the contents of a house, from an enclosure smaller than a stack of LPs."* Audiophile Review

This is the subwoofer that started the revolution…in a dramatically upgraded form. At 11 inches cubed, the Sunfire True Subwoofer (now fifth generation with built-in equalization) re-defines the term "spouse friendly." The True Subwoofer EQ is small enough to fit into practically any music or theater system to quickly add stunningly high levels of deep and musically accurate bass.

It's easy to set up because we gave it built-in diagnostics that automatically smoothes its output frequency contour to your unique listening room (see further explanation on the EQ Signature page).

The True Subwoofer EQ incorporates two of Bob Carver's 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.

And now we've added a balanced input and made it "smart" by adding a measurement microphone and internal contour circuitry. When you add it all up, The True Subwoofer EQ has absolutely no performance equal its size.
