The American Bass SQ Series coaxial speakers are designed as a direct, high-quality upgrade for factory speaker systems. Trusted by dealers and enthusiasts for years, the SQ lineup delivers improved clarity, balanced frequency response, and reliable power handling without the need for extensive system modifications.
This combo set pairs 6.5-inch SQ6.5 coaxials with 6x9-inch SQ6.9 coaxials, making it an ideal solution for vehicles that use mixed door and rear-deck speaker sizes. Both speaker models feature woven carbon glass fiber cones for added rigidity and detail, combined with butyl rubber surrounds for controlled excursion and long-term durability.
High frequencies are handled by neodymium swivel tweeters, allowing for better sound staging and improved clarity compared to fixed tweeter designs. Ferrofluid cooling helps manage heat during extended play, while stamped steel baskets and rubber magnet boots provide structural stability and protection.
Designed to run on factory radios or aftermarket amplifiers, the American Bass SQ6.5/SQ6.9 combo delivers clean, full-range sound with increased output and clarity over OEM speakers.
