Polk DB5252 5.25" Component Speaker System with Marine Certification
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.
The Polk DB5252 5.25" Component Speaker System with Marine Certification delivers legendary sound quality that transforms your vehicle's audio experience. Engineered and designed in Baltimore, Maryland, these speakers feature an IP56 waterproof rating and are tested for salt-fog, UV and humidity. The DB+ Series are Marine Certified to push the limits of durability, so you can take them anywhere.
Superior Sound Engineering
Polk's exclusive lightweight Dynamic Balance® Polypropylene Cones deliver spectacular midrange clarity, punchy bass and high efficiency. The system includes separate 5.25" woofers and 0.75" silk dome tweeters with external crossovers that direct frequencies to the proper drivers for seamless performance. Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance.
Universal Installation Compatibility
Built marine tough and designed for a universal fit, DB+ series power the soundtrack of your ride wherever life takes you, on the road, the trail, the waves—you name it. The zero-tweeter protrusion design ensures that your factory grilles reinstall seamlessly, while the included mounting options accommodate both flush and surface tweeter installations.
Marine-Grade Durability
Each speaker has a non-corrosive plastic grille, a polypropylene UV tolerant cone, waterproof inner and outer surrounds, and stainless steel mounting hardware, ensuring that they are fully protected against the elements. Waterproof surrounds completely block dirt, liquid, and grime from entering the speaker housing—all designed to maximize longevity of the speaker.

Frequently Asked Questions
Are these items authentic, and why are the prices so low?
This sale includes demo units we've used for customer demonstrations since 2016, new-old-stock from discontinued product lines, display models from trade shows, and carefully curated inventory we've collected over nearly a decade. Most items include original packaging where available.
What types of items are included in the relocation sale?
Our relocation sale includes demo units we've used for customer demonstrations, new old stock from discontinued product lines, and display models from trade shows. All items are genuine products from top car audio brands - we're simply clearing inventory we can't take to our new location. Items range from amplifiers and speakers to processors and accessories accumulated over nearly 10 years at this location.
Do sale items come with manufacturer warranties?
Warranty coverage varies by item and condition. New old stock items typically include full manufacturer warranty if still valid. Demo and display items may have limited or no manufacturer warranty remaining. We clearly state warranty status in each product description. All sales are final on relocation sale items.
How does shipping work for relocation sale items?
We ship relocation sale items using the same careful packaging methods as our regular inventory. Shipping costs are calculated at checkout based on size and weight. For multiple item purchases, we'll combine shipping where possible to save you money. Large items like subwoofer boxes may require freight shipping with additional costs.
Can I return or exchange relocation sale items?
All relocation sale items are sold as-is with no returns or exchanges. We encourage local pickup customers to inspect items before purchasing. For shipped items, we provide detailed descriptions and photos. Since we're relocating, we cannot accommodate returns or warranty service after the sale period ends.
