MB Quart XK2-116 6.5" 2-Way Coaxial Speakers

The MB Quart XK2-116 is a pair of 6.5-inch, 2-way coaxial car speakers designed for replacing or upgrading compatible factory door speakers. Its coaxial layout combines the woofer and tweeter in each speaker, helping simplify installations where a separate tweeter location is not available. This makes it a practical option for vehicle owners seeking a straightforward full-range speaker upgrade.

The XK2-116 is rated at 120 watts RMS and 240 watts peak power per pair. With 88 dB sensitivity and a 55 Hz to 22 kHz frequency response, it is specified to cover bass, midrange, and high-frequency information within a typical car-audio speaker system. The 4-ohm impedance suits many conventional automotive speaker circuits.

Each speaker uses a coaxial 2-way configuration with a centrally mounted bullet-style tweeter. This arrangement is intended to reproduce high frequencies from the same mounting location as the 6.5-inch woofer. A neodymium magnet is also specified for the speaker design.

For fitment, the XK2-116 has a 5.59-inch cutout requirement and a 2.13-inch mounting depth measured from the flange. Those dimensions are important when checking clearance behind a factory door panel, rear deck, or custom speaker location. The speakers are specified for door mounting, but vehicle-specific fitment should be verified before purchase.

The XK2-116 can be used as part of a factory-speaker replacement project or alongside a compatible aftermarket car-audio system. Included speaker wire supports basic installation, while vehicle-specific adapters, mounting hardware, and harnesses may still be needed depending on the application. Match the speakers to a compatible 4-ohm source or amplifier and confirm mounting measurements before installation.

Key Features

• 6.5-Inch Coaxial Design: Combines woofer and tweeter functions in each speaker.
• 2-Way Configuration: Supports full-range reproduction from a single mounting location.
• 120W RMS Per Pair: Provides a stated continuous power-handling reference for system matching.
• 4-Ohm Impedance: Fits many standard automotive speaker-output configurations.
• 55 Hz–22 kHz Response: Covers a broad stated range for music playback.
• Neodymium Magnet: Uses a specified neodymium-magnet speaker motor design.

Design & Installation

The XK2-116 has a black-and-red automotive speaker design with a centrally positioned bullet-style tweeter and a neodymium magnet. Its coaxial construction places the high-frequency driver within the woofer assembly, reducing the need for a separate tweeter mount. The speaker is intended for car-audio use and door-mount applications.

Check that the vehicle accepts a 6.5-inch speaker, provides at least 2.13 inches of depth behind the mounting surface, and accommodates a 5.59-inch cutout. Use the included speaker wire as appropriate, and plan for vehicle-specific mounting adapters, fasteners, or wiring harnesses if the factory installation requires them. Verify polarity and use a compatible 4-ohm source or amplifier when connecting the speakers.
