PRV Audio 12W800A Alto Series 12" Pro Woofer 8 OhmHigh fidelity meets high output in PRV Audio's Woofers. Experienced audio engineers and musicians know that tone is crucial to a great performance, whether in the studio or on stage. That’s why PRV Audio’s Alto Series woofers are thoughtfully designed and voiced to deliver smooth, natural sound with dynamic range.
With greater excursion and higher power handling than PRV’s , the 12W800A Alto Series 12″ professional woofer delivers more output capability and stronger low-frequency impact.
Nominal Impedance: 8 Ohms800 Watts program RMS power delivers strong acoustic output55 to 5,800 Hz frequency response makes this midbass/woofer ideal for two- or three-way designsHandles extreme output levels with 97 dB sensitivity5.72 mm Xmax enables excellent excursion for impactful bass performance
The 12W800A’s rugged build makes it dependable for heavy-duty use, offering long-lasting durability in high-demand situations. Its advanced thermal management system keeps the driver running cool under stress, while its low distortion design provides powerful midbass that remains dynamic, clear, and accurate across applications.
Equipped with a multi-roll surround, oversized raised spider, and lightweight 2.50″ voice coil, the 12W800A delivers high output levels without sacrificing control. This careful combination of components helps maintain stability during large excursions while minimizing unwanted distortion, resulting in a clean, impactful performance.
With its generous 5.72 mm Xmax, the 12W800A is built to handle deep excursion tones while preserving clean, accurate playback. This capability translates into powerful low-frequency output that maintains clarity and definition, even when reproducing vocals. Whether you’re designing a home theater system or building a high-output car audio setup such as a stuntwall, the 12W800A delivers the precision and authority needed for impactful sound. Its ability to combine strong bass performance with detailed reproduction makes it a versatile choice across demanding applications.
This Woofer works great as a midbass speaker for custom car audio systems, designed for use in compact ported box, also works very well as door speakers. See stuntwall recommended box for optimal output below:
4 Triangle Ported box volume: 0.70 ft³ (approx: 12” x 12” x 8.5” inside dimensions) ¾ Wood Port size: 3” x 3”x 4.25” by 5” deep.
How to Install them: This midbass speaker will need 800 Watts RMS per speaker with recommended HPF using
115 Hz at 12 dB per octave filter Crossover / BT12 105 Hz at 18 dB per octave filter Crossover / BT18
4 Speakers – 1x , 4 speakers in parallel 8 Speakers – 1x , 8 speakers in parallel
If you have compression drivers on your system the recommended LPF is 2,000 Hz at 18 dB per octave filter Crossover / BT18 but you may set it lower to blend in better depending on the other components in your system, or you may not use a LPF at low power to take advantage of its high frequency response

Keeping this power for a little longer timer will damage the speaker.
