The GX600C's Plus One woofer cones provide more overall speaker cone area than others in the class. With an effective increase in cone area, the speaker radiates more air. The result is a better low-frequency response and a greater ability to make those important musical notes that people often associate with larger speaker sizes.
Soft dome tweeters deliver a smooth high-frequency response and an increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos.
