Wisdom Sub Is Big, to State the Obvious

Jon Herron was kind enough to pose next to Wisdom Audio's STS sub, with dual 15-inch woofers in a fridge-size cabinet that can vent through front or side. It is up to 101dB sensitive, make that 130dB at 20Hz, and don't try that at home. Price $10,000, shipping end of month. See item by Tom Norton.
