PreSonus - Temblor T8 (8" Active Studio Subwoofer)

Designed for critical listening in the studio or at home, the PreSonus Temblor T8 Active 8" Studio Subwoofer complements any full-range monitoring system, and is suitable for use in a variety of applications such as music production, gaming, and home theater, and more.

The Temblor T8 features an 8", down-firing, glass-composite woofer which is powered by a Class AB amplifier that delivers 200 watts of power. It has a round, front-firing acoustic port, 1/4" TRS and RCA main inputs, and 1/4" TRS and RCA pass-through outputs to connect your top speakers.

The speaker also includes a continuously variable low-pass filter that can be set between 50 Hz to 130 Hz, and also has a switchable high-pass filter that removes content below 80 Hz from the full-range signal sent to your satellite speakers, allowing you to create a seamless crossover transition.

  • 8-inch, downward-firing, glass-composite low-frequency transducer
  • Round, rear-firing, bass-reflex acoustic port
  • Polarity invert assures the sub is phase aligned with top speakers
  • Internal damping and heat sink
  • Integrated rubber feet for stable placement
