2x 10W650A-4 10" PRO AUDIO WOOFER
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.
To get the right sound, a special composite cone is built with non-pressed paper (visible on the backside) for the reduced break-up and smooth sound. A unique, woven-cloth dust cap helps to achieve high sensitivity by reducing moving mass while helping to cool the voice coil.
You’ll find that Alto Series woofers work remarkably well vented and sealed cabinets, as woofers in two-way speakers or midrange speakers in three-way systems, and even shine when used as the bass guitar and guitar speakers. Upgrade to the PRV Audio ALTO Series… You’ll thank us later!
