To hear what's really going on at the bottom of your mixes, you need a subwoofer that speaks the truth. The Temblor T8 lets you take charge of the low-frequency foundation of your mix with a combination of quality components and design, plenty of inputs and outputs, and extensive user controls not normally available in this price range.

An ideal companion 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 system's low end with a musical and natural approach.
Powerful and musical, Temblor features high-quality components and design that enable it to deliver fast and accurate transient response, extending low frequencies without a hint of "tubbiness" or overshoot.
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.
When you choose the T8, 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 T8 provides more user controls than any other subwoofer in it's class, enabling seamless integration into your listening environment.

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.
Of course, we didn't forget the "small things" that can make a big difference: The T8 has a polarity invert feature.

No other subwoofer anywhere close to the Temblor's price range offers a comparable selection of inputs and outputs.

The T8 provides two sets of inputs: left and right, balanced 1 / 4" 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 1 / 4" 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.
