Technical Performance You Can Hear
The SYN 5"x7" coaxials are designed for clean, efficient output and smooth frequency response in real-world vehicle installs. A properly damped midbass driver delivers tight, controlled lows ideal for door mounting, while the high-efficiency tweeter provides crisp highs without harshness. With a well-balanced impedance load and strong sensitivity, these speakers perform exceptionally well on factory power upgrades or aftermarket amplifiers alike.
Built with durable materials, optimized motor structures, and a design focused on linear response and thermal stability, the SYN Series excels in daily-driven systems that demand consistency, clarity, and long-term reliability. The result is a speaker that plays loud when asked, stays clean under power, and delivers detail that keeps your music engaging—not fatiguing.
