Used but in excellent condition. Everything works perfectly and there are no cosmetic issues.

I'm selling it because I downsized to a 2-channel stereo system and simply don't need a subwoofer of this size anymore. It's an outstanding performer - just overkill for my current setup.

If you're considering SVS or Rythmik, the HSU ULS-15 MK2 deserves to be on your shortlist. It's widely regarded as one of the best values in high-performance sealed subwoofers, delivering deep, accurate bass for both music and home theater.

Highlights

• 15" high-excursion driver
• 600W continuous / 2,000W short-term RMS amplifier
• Sealed enclosure for tight, musical bass
• Frequency response: 20–200 Hz (±1 dB)
• Variable Q Control (0.3–0.7) for tuning bass characteristics
• Balanced XLR inputs plus RCA and speaker-level inputs
• Smooth satin black finish with magnetic grille
• 65 lbs.
