I’m selling my Harman Kardon active powered subwoofer. I’ve had it about 5–10 years and it’s in good working condition with normal home use. It’s a wired subwoofer with bass boost and standard speaker-level and line-level inputs. No warranty remains. The cabinet has some minor surface marks from regular use but nothing affecting performance. I’m including the unit as shown — ready to connect to an AVR or amplifier. Product specifications: - Brand: Harman Kardon - Type: Active powered subwoofer - Age: 5–10 years - Condition: Good - Connectivity: Wired (speaker-level and line-level inputs) - Features: Bass Boost - Warranty: No - Usage: Normal use
