The PreSonus Temblor T8 Subwoofer allows you to take charge of the low-frequency foundation of your mix with a combination of high quality components and design plenty of inputs and outputs and extensive user controls enabling seamless integration into your setup. The T8 provides two sets of inputs; left and right balanced 1/4 TRS and unbalanced RCA main inputs allowing the subwoofer to pair with PreSonus BT-series active speakers and home stereo speakers. The Temblor T8 Active Subwoofer is the perfect companion to the to Eris™ and Sceptre™ active reference monitors and Ceres BT-series active speakers. Temblor-series subwoofers complement full-range monitors without overshadowing them extending the reach of your full-range systems low end with a musical and natural approach. Suitable for Any Environment Suitable for personal studios gaming audiophiles and home theaters the T8 uses a downward-firing 8 glass-composite driver with high-density rubber surround and a round rear-firing bass-reflex acoustic port. Its 200W Class AB amplifier (100W RMS) delivers up to 104 dB SPL with a frequency response of 30 Hz to 300 Hz. Extensive User Controls The Temblors extensive user controls include input gain (-30 dB to +6 dB continuously variable) and a continuously variable lowpass filter (50 Hz to 130 Hz) allow you to create a seamless crossover transition between your full-range studio monitors and subwoofer for a more accurate listening environment. Highpass Filter A switchable highpass filter removes frequency content below 80 Hz from the full-range signal sent from the Temblors outputs to the main monitors avoiding destructive cancellation and reinforcement in the subwoofers upper range. The result is a subwoofer that can be adjusted to perfectly complement not only the Sceptre™ CoActual™ Eris™ and Ceres™ BT active studio monitors but virtually any studio monitor.
