About the Sub Nine
The Vandersteen Sub Nine is a premium powered subwoofer sold in stereo pairs, originally developed as the bass section for a statement-level speaker but excels as a standalone solution for enhancing bass with the Model 7 floorstanders or other high-quality speakers. Each enclosure houses a 13-inch downward-firing, slot-loaded woofer with a patented cellulose-fiber/foam cone and a 400-watt Class B linear balanced bridge amplifier with switching power factor corrected regulated power supply. Key features include 11-band room equalization, continuously adjustable contour control (Q=0.5 to 1), level control for speaker sensitivities from 82 dB to 92 dB, and high-level inputs via 5-way binding posts or banana plugs. This allows precise tailoring to any listening room for optimal bass performance. Manufactured in the USA with standard high-gloss automotive paint finishes.
