The DESMB12A Active Slot-Vented Subwoofer Enclosure from Diamond Audio delivers powerful, controlled bass performance in a compact, ready-to-install design. Part of the Diamond Elite DES Series, this active subwoofer system reflects premium craftsmanship and precision engineering, offering dynamic low-frequency output with the signature Diamond Audio sound.
At its core is a high-performance 12-inch DES Series subwoofer featuring a reinforced hybrid paper fiber cone designed to handle demanding power levels while maintaining accuracy and durability during extended listening sessions. The slot-vented enclosure enhances low-end efficiency and output, producing deeper, harder-hitting bass compared to sealed designs.
The DESMB12A is housed in a rigid, high-strength MDF enclosure with extensive internal bracing and lock-tight fastening to eliminate unwanted resonance, air leaks, and distortion. Its compact Microbox-style footprint makes it ideal for vehicles where space is limited but strong bass impact is still desired.
With an optimized 2-ohm configuration and an integrated active design, the DESMB12A simplifies installation while delivering impressive output. For enthusiasts seeking premium bass performance in a space-efficient package, the DESMB12A is the ultimate all-in-one subwoofer solution.
