Powerbass STA-8 8" Amplified Bass Enclousre


The STA-8 Features a Class A/B mono amplifier perfectly matched to power the 8-inch woofer in its vented enclosure design. Powerbass developed a compact trapezoid shaped enclosure, perfectly tuned to get the most out of the proprietary 8-inch subwoofer. The geometric design maximizes transient response, reducing the negative effects that a sma enclosure can have on the subwoofer by dispersing and dissipating standing waves away from the subwoofer and result in cleaner, deeper bass in less space.
