Designed for true audiophile sound with SPL capability, the QEX-800SQ delivers tight, fast, musical bass with serious output. Engineered to move large amounts of air while maintaining accuracy, this 8” long-excursion sub easily overcomes road noise without sounding boomy or sloppy. The result is clean, controlled low-frequency performance with exceptional detail, whether you listen to jazz, rock, or high-level bass tracks.
Built with a heavy-duty cast aluminum basket and optimized motor system, the QEX-800SQ provides lower distortion, higher clarity, and outstanding reliability. Designed in California by CDT Audiophile engineers and built under strict quality control for premium sound performance.
Its 2nd-generation transparent silk dome design provides performance comparable to high-end exotic metal domes, but at a breakthrough price. Unlike competing tweeters, the ES-1200iS boasts superior on-axis and off-axis response. In fact, no other tweeter on the market matches its off-axis performance. Just take a look at the response curves (see PDF file below) across 0°, 15°, 30°, 45°, and 60°. Notably, at 45°, the ES-1200iS maintains a flat response up to 15kHz—a feat that enhances openness, clarity, and overall audio realism.
This superior performance isn’t just about the dome shape—it’s achieved through the unique formed-film structure within the dome, setting a new benchmark in car audio engineering. Experience the ES-GOLD Series and elevate your in-car audio to unparalleled fidelity.
