Presonus Temblor T8 Subwoofer

The new PreSonus T8 Subwoofer provides more user controls than any other subwoofer in their class, enabling seamless integration into your listening environment.This is a very well-priced subwoofer packed with features you won't find anywhere in this price range, with plenty of ins and outs and delivering all the low end you'll need!

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.

The result is a subwoofer that can be adjusted to perfectly complement not only our Sceptre™ CoActual™, Eris™, and Ceres™ BT active studio monitors but virtually any studio monitor.

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.

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.
