Overview

PRV Audio 12W800A Alto Series 12" Woofer 8 Ohm

PRV Audio 12W750A Alto Series 12" Woofer 8 Ohm

High fidelity meets high output — PRV Audio Alto Series 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.

  • Nominal Impedance: 8 Ohms 
  • 800 Watts program RMS power delivers strong acoustic output 
  • 55 to 5,800 Hz frequency response makes this midbass/woofer ideal for two- or three-way designs 
  • Handles extreme output levels with 97 dB sensitivity
  • 5.72 mm Xmax enables excellent excursion for impactful bass performance

With increased excursion and greater power handling than PRV’s popular 12W750A, the 12W800A Alto Series 12″ professional 8-ohm woofer delivers enhanced output and deeper low frequency punch. 

Engineered for use in compact ported enclosures, the 12W800A is an excellent choice for systems demanding both high efficiency and high output. This low frequency midbass has been carefully voiced for a natural tone with minimal distortion at elevated volumes. It features a multi-roll surround, large raised spider, and a lightweight 2.50″ voice coil to deliver powerful performance while maintaining clean sound.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
**Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to provide a clean signal without clipping or saturation.
***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
