10 Inch Subwoofer Appraisal

Alpine Type-R 10-Inch Subwoofers in Bbox Custom Enclosure

This is a dual-subwoofer audio setup featuring two 10-inch Alpine Type-R drivers mounted in a specialized 'Bbox' branded enclosure. The subwoofers are distinguished by the signature red 'R' logo on the dust caps and heavy-duty ribbed surrounds designed for high excursion. The enclosure is constructed from medium-density fiberboard (MDF) and wrapped in a charcoal gray automotive-grade carpet. The shape of the enclosure is notable; it appears to be a vehicle-specific 'stealth' or 'under-seat' box with a non-rectangular, tiered profile intended to fit the contours of a specific truck or SUV cabin. The enclosure features a visible 'Bbox' manufacturer's badge on its front surface. Regarding condition, the carpet shows visible lint, dust, and minor pilling consistent with storage in a garage environment. There are no obvious tears in the woofer surrounds or punctures in the cones, though the proximity to heavy tools like the red vise suggests a risk of cosmetic dings. The craftsmanship of the Alpine drivers is high-tier for consumer car audio, known for large ferrite magnets and dual voice coil configurations. The item likely dates from the mid-2010s. For appraisal purposes, the functionality of the voice coils remains untested, and the internal wiring terminals are not visible in this orientation.
