A solid foundation for mixing
A subwoofer provides the extra-deep low frequencies you need when mixing on relatively small monitors, especially for music that requires serious low-end punch. Powerful and musical, Temblor® T8 active, downward-firing subwoofers are designed to deliver fast and accurate transient response, extending low frequencies without a hint of “tubbiness” or overshoot. This ensures that Temblor-series subwoofers complement full-range monitors without overshadowing them, naturally extending the reach of your full-range system’s low end so that you can produce your best mix from top to bottom.

Includes: (1) IEC power cable

Tight, clean, responsive bass
The Temblor T8’s glass-composite low-frequency driver delivers tight and responsive bass, thanks to its lightweight and rigid cone. This design also provides lower distortion than other materials, ensuring that the sub-bass reproduction in your monitoring system is as coherent and clear as your full-range monitors.

A perfect fit with your full-range monitors
Temblor-series subwoofers make integrating a subwoofer into your monitoring setup easy so you can create the most accurate possible response. The Temblor T8 provides a continuously variable lowpass filter (50 Hz to 130 Hz), allowing you to create a seamless crossover transition between your full-range studio monitors and subwoofer for the most accurate listening environment possible.

The central hub of your monitoring setup
Temblor subwoofers provide the connections and controls necessary to act as the central hub for a basic monitoring setup. A switchable highpass filter on the full-range outputs helps to avoid frequency cancellation and reinforcement in the subwoofer’s upper range. A polarity invert ensures your system is in phase.

Accuracy defined
When you hear the low-frequency foundation of your mix accurately, you can make more informed decisions and create more translatable mixes. Temblor T8 subwoofers are the natural sub-bass extension for virtually any small full-range studio monitoring system, home stereo, or home theater system.
