Tuning The Amplifier - Front or Rear Speakers

6) Input Sensitivity Control

Slowly rotate the control clockwise (refer to the diagram on page 5) until maximum undistorted playing level is heard from the speakers. Listen closely for bottoming from the speakers. If detected, rotate the input sensitivity control counterclockwise until it is eliminated.

7) Crossover Controls

To achieve higher undistorted playing levels from the main speakers, the highpass crossover must be engaged. Rotate the crossover control fully clockwise (refer to the diagram on page 5). The highpass crossover point is now set at 350Hz. Rotate “Q-Tune™” Control fully counterclockwise. Move crossover switch to the right (ON) position.

Slowly rotate the input sensitivity control clockwise until maximum undistorted playing level is heard from the speakers. Listen closely for bottoming from the speakers. If detected, rotate the input sensitivity control counterclock- wise until it is eliminated. Slowly rotate the highpass crossover control counterclockwise while listening for bottoming. You are lowering the crossover point, which means that more bass signal is being sent to the speakers. If bottoming is detected, rotate the input sensitivity control counterclockwise until it is eliminated and/or rotate the Highpass crossover control clockwise to raise the crossover point.

8) Q-Tune™Control

Once the highpass crossover point has been determined, use the Q-Tune™control (refer to the diagram on page 5) to increase the bass information centered around the crossover point.

Setting the Q-Tune™control is done in conjunction with setting the levels on the input sensitivity and highpass crossover frequency controls. You may find while setting the Q-Tune™that over-excursion may be detected in the front speakers; lowering the Q-Tune™input sensitivity or raising the highpass crossover point will eliminate this. Minor adjustments to each setting are required to fine-tune the system.

Setting the Q-Tune™is a subtle process. It is recommended that the Q-Tune™setting be left in the 0.7 position and adjusted only after the input sensitivity and highpass crossover ranges are known. Small adjustments to the Q-Tune™setting are all that are required to fine-tune the system.

The GT-2200 is particularly celebrated for its robust construction and exceptional sound clarity. Featuring a 2-way design, it incorporates a 6.5-inch polypropylene woofer, which ensures deep bass response, complemented by a 1-inch silk dome tweeter for crisp high frequencies. This combination results in a well-balanced audio performance, making it suitable for various types of music. The speaker also boasts a frequency response range from 40Hz to 25kHz, allowing listeners to experience a rich soundstage.

Next, the GT-2125 takes a similar approach with its 2-way design but enhances the audio experience with a larger 8-inch woofer. This added driver size provides even more depth to the bass while maintaining clarity in vocals and instruments. The GT-2125 also features a sleek cabinet design that minimizes resonance and distortion, ensuring that the sound remains clean and true to the original recording. Additionally, its high-quality crossover network seamlessly blends the sound from the woofer and tweeter for a cohesive listening experience.

The GT-275 stands out with its powerful 3-way configuration, incorporating a 10-inch woofer, a mid-range driver, and a tweeter. This triad of drivers allows for a more dynamic sound reproduction, making it well-suited for home theater setups. The GT-275 is engineered with advanced technologies, including Boston Acoustics’ patented power handling capabilities, which help ensure that the speakers can withstand high volumes without compromising sound quality.

Finally, the GT-2300 offers a versatile experience with its bi-amping capability. Users can connect separate amplifiers to the woofer and tweeter, allowing for tailored sound adjustment based on personal preferences and room acoustics. This model features a durable cabinet design that offers both aesthetic appeal and acoustic performance.
