Proline X Performance Optimized Single 10 inch Ported Box
Professionally Maintained Demo Units
Every demo unit has been carefully maintained by our certified technicians. These aren't customer returns or damaged goods - they're the same high-quality equipment we've used to demonstrate premium sound to our customers for years.
Pre-Tested & Verified
Unlike typical clearance sales, every item has been tested and verified by our technical team. We stand behind the quality of our relocation inventory.
Everything Must Go Pricing
These aren't regular sale prices - this is genuine "moving warehouse" pricing. Discounts you simply won't find under normal retail circumstances.
Trade Show Display Models
Many items are pristine display models from major audio trade shows - equipment that's been seen but never installed. These pieces often include special editions or limited releases not available through regular retail channels.
