QPower QBOMB12VL Dual 12" Vented Sub Box vs Proline X P12D-P Dual 12" Ported Enclosure
Buy the Proline X if you want a tighter, better-built box tuned for deep output and backed by a warranty. Buy the QPower if you want the most internal air space and a rugged spray finish for a big, boomy build. The QPower is larger and cheaper-feeling in construction, with no written warranty and vague power specs. The Proline X uses CNC-cut joinery, pre-wired 12-gauge OFC wire and a recessed composite terminal cup, and owners of the line report solid build quality.
- Choose the QPower QBOMB12VL if you want maximum air space (about 4.5 cu ft total) for two 12s and a tough bedliner-sprayed finish.
- Choose the Proline X P12D-P if you want a precisely tuned, well-joined enclosure with pre-wired internals and a one-year warranty.
