Pure Aluminum Ribbon Tweeter System. The G3ST-D is designed to add improved high frequency range, detail and staging depth to almost any system. It is the dipole version of our G2ST adding a rear-facing ribbon tweeter to the system. Allows users to approximate the high frequency performance of our Grand Harmony, Grand Supreme and Genesis Models. With a built-in selectable crossover at either 10KHz or 16KHz and output controls from -3dB to + 3dB in 1.5dB steps, the G3ST-D is easy to integrate with just about any speaker. Adds the air, speed and resolution associated with the famous Aurum Cantus ribbon tweeter technology. Highly recommended for electrostatic and magnetic-planar speakers. Employs the specifically designed G3ST (front) and G2ST (rear) ribbon tweeters only found in the ST Super Tweeter Series. Best when mated with speakers having a sensitivity between 88dB - 98dB. Supplied in High-Gloss Piano Black Finish (requires a flat surface of at least 5.5" W x 8.5" D for secure placement).
