Presonus Temblor T8

8" Active Subwoofer with built in crossover

Suitable for personal studios, gaming, audiophiles, and home theaters, the smaller T8 uses a downward-firing, 8-inch 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.

Whether you choose the T8 or the T10, you’ll have a subwoofer that delivers accurate, smooth tight low end and outperforms subs costing far more. With Temblor, you hear what the foundation of your mix really sounds like so you can produce your best mix from top to bottom.

The Temblor’s extensive user controls include input gain (-30 dB to +6 dB, continuously variable) and a continuously variable lowpass filter (50 Hz to 130 Hz) that let you create a seamless crossover transition between your full-range studio monitors and subwoofer for a more accurate listening environment.

A switchable highpass filter removes frequency content below 80 Hz from the full-range signal sent from the Temblor’s outputs to the main monitors, avoiding destructive cancellation and reinforcement in the subwoofer’s upper range.

T8 Ins and Outs

The T8 provides two sets of inputs: left and right, balanced ¼” TRS and unbalanced RCA main inputs. This enables it to pair well with PreSonus’ Ceres BT-series active speakers and home-stereo speakers, as well as personal-studio systems.

Similarly, the T8 offers left and right balanced ¼” TRS and unbalanced RCA pass-through outputs for connecting satellite speakers.

So if you want a system with XLR connections or want to use two subwoofers, go with the T10. If you are using your subwoofer with a home stereo or home theater system or a smaller studio system that does not require XLRs or two subwoofers, consider the T8.
