PreSonus Temblor T8 Powered Subwoofer

Suitable for serious personal studios, gaming, audiophiles, and home theaters, the Temblor T8 active subwoofer complements full-range home-stereo speakers and studio reference monitors—including the PreSonus Eris and Ceres BT series—without overshadowing them. Powered by a 200W (100W RMS) amplifier, the T8 features an 8-inch, down-firing, glass-composite woofer; built-in crossover; ¼-inch TRS, and RCA inputs and outputs; and a front-firing acoustic port. It offers extensive user controls not usually found in this price range, including a switchable high pass filter that removes content below 80 Hz from the full-range signal sent to the main speakers and a variable low pass filter for creating a seamless crossover transition.
