Powerbass STA-10 - 10" Amplified Underseat Subwoofer Enclosure



The STA-10 features an Ultra Efficient Class D mono amplifier perfectly matched to power the 10-inch woofer in our exclusive passive radiator design for more bass in less space. We developed a compact trapezoid shaped enclosure, perfectly tuned to get the most out of the proprietary 10-inch subwoofer. The geometric design maximises transient response, reducing the negative effects that a small enclosure can have on the subwoofer by dispersing and dissipating standing waves away from the subwoofer and result in cleaner, deeper bass in very small space.

Supplied with “plug in” connectors for speakers and power, installation is simple and straightforward. Also, since no holes need to be cut, the STA-10 is a perfect choice for leased vehicles that could use a little extra bass.
