the Sunfire True Subwoofer MKII designed by audio legend Bob Carver.

Tiny Box, Legendary Earth-Shaking Bass."
The Sunfire True Subwoofer MKII revolutionized the audio world by producing massive, ultra-low sub-bass down to 18 Hz out of an incredibly compact 11-inch cube. Powered by Bob Carver's patented 2,700W Tracking Downconverter amplifier and a dual-driver push-pull configuration, it delivers room-shaking output without taking up floor space.

Sound Profile: Fast, deep, and authoritative. It excels at adding tactile weight and impact to movie soundtracks while opening up the soundstage and midrange for stereo music playback when properly integrated.
​
the Verdict: A true classic in high-end audio. Highly sought-after by audiophiles and home theater enthusiasts who want reference-level low-frequency extension without a massive cabinet taking over the room.

NOTE 1: There are many imperfections on the enclosure due to its age hence the price. Still in very perfect functional condition and I think it's still presentable.

NOTE 2: This unit is 120V so Sunfire transformer is also included in the package as seen on the last photo. Be mindful of the total weight as it will be shipped.
