High fidelity meets high output — PRV Audio ALTO Series Woofers. Audio experts and professional musicians know that tone can make or break a performance, in the studio or on the stage. That’s why PRV Audio’s Alto Series woofers were carefully crafted and voiced to create a natural, smooth sound while remaining dynamic.
Highlights
- Nominal Impedance: 8 Ohms
- 800 Watts Program RMS power makes high acoustical output
- 55 to 5,800 Hz frequency response makes this midbass/woofer suitable for two or three-way designs
- Capable of extreme output levels with 97 dB sensitivity
- 5.72 mm Xmax allows excellent displacement for high impact bass capability
With improved excursion and higher power handling over PRV’s popular 12W750A, the 12W800A Alto series 12″ professional 8-ohm woofer offers improved output capability and more low frequency impact.
Designed for use in a compact ported box, the 12W800A is a great choice for any system where high efficiency and high output is the goal. This low-frequency midbass has been painstakingly voiced to create a natural tone with low distortion at high levels. Featuring a multi-roll surround, large raised spider, and 2.50″ light-weight voice coil, the 12W800A is capable of high output while keeping distortion under control.
