FKB116S

Slim-Mount High-Performance Audio Upgrade

Upgrade your vehicle’s sound system with the MB Quart FKB116S Formula Series 6.5-Inch Slim Mount 2-Way Coaxial Speakers. Designed specifically for tighter factory installations, these speakers deliver powerful, clean audio performance while fitting into shallow mounting locations where standard speakers may not fit. With up to 120 watts peak power handling, they provide a noticeable improvement over factory audio systems.

The slim design allows for versatile installation in a wide range of vehicles, making it an ideal choice for drivers seeking better clarity, stronger midbass, and overall improved sound without major modifications.

Engineered Materials for Clear and Reliable Sound

The MB Quart FKB116S speakers are built using advanced materials designed to improve durability and sound quality. The aluminum dome tweeters provide crisp, detailed high frequencies with excellent long-term reliability. Combined with lightweight thermal-formed polypropylene cones, these speakers deliver fast, accurate midrange response for a more natural and dynamic listening experience.

The butyl rubber surrounds enhance cone control and improve midbass impact while increasing durability over time. A high-temperature adhesive bond between cone and surround ensures structural integrity even under high power output or extreme environmental conditions, making these speakers highly reliable for long-term use.

Durable Construction for Long-Term Performance

The MB Quart Formula Series FKB116S is engineered for strength and stability in demanding automotive environments. A textured ABS gasket provides a secure and rigid seal against the mounting surface, reducing vibration and improving acoustic efficiency.

With slim mount design engineering, these speakers are ideal for vehicles with limited installation depth while still delivering strong audio performance. Rated for 60 watts RMS at 4 ohms, they provide consistent output suitable for factory head units or modest aftermarket amplifiers.

Whether upgrading daily drivers or enhancing custom builds, the FKB116S offers dependable MB Quart performance in a compact, easy-to-install form factor.
