About: Alpine W-DB12V Dual 12" 500W RMS Loaded Subwoofer Enclosure

Bully the competition with the Alpine W-DB12V Dual Bass Series Wedg-E Enclosure, built to deliver relentless, hard-hitting bass with authority.

Bass that Hits Harder

No competition here—the Alpine W-DB12V Dual “Wedg-E” Enclosure is built to outmuscle typical subwoofer boxes. Loaded with dual 12" Bass Series subwoofers and an intentionally engineered vented enclosure, it delivers relentless, high-output bass with serious punch. This optimized design allows the system to hit harder and move more air without fear of overdriving, giving you powerful, controlled performance that refuses to back down.

Optimized Enclosure Design

The W-DB12V’s wedge design isn’t just about fit, it’s about force. Designed to align with rear seat angles, it makes efficient use of your cargo area while directing powerful bass into the cabin. Even with dual subwoofers, the enclosure maintains a clean, integrated fit. The angled design helps reduce internal wave interference, keeping output tight, consistent, and focused.

Precision-Tuned Vented Enclosure

Engineered for maximum performance, the W-DB12V features a precision-tuned vented enclosure with a curved port designed to handle increased airflow from dual subwoofers. This results in deeper low-frequency extension, higher output, and strong performance under pressure. With optimized internal volume and port tuning, the Wedg-E enclosure delivers powerful, consistent bass that hold up even at demanding listening levels.
