Premium Series 6.5" Coaxial Speakers

The MB Quart PK1-116 is a pair of 6.5-inch two-way coaxial speakers built for car audio enthusiasts who want a direct-fit upgrade. They combine a lightweight aerated pop paper cone with a Mica blend and a 1-inch magnesium dome tweeter. The design targets drivers seeking improved clarity and bass response over factory-installed units without requiring custom fabrication.

Magnesium WideSphere Tweeter Technology

The defining specification is the 1-inch magnesium dome tweeter paired with WideSphere Technology. A tunable waveguide housing includes a removable phase lens and an off-axis dispersion pattern that work together to create a larger, aimable sound stage. This tweeter design determines whether the high-frequency dispersion matches the listener's preferred imaging requirements.

Bass Response and Frame Rigidity

The curvilinear cone with Mica blend delivers superior bass frequency reproduction within the constraints of a 6.5-inch coaxial format. An aerospace-grade PA66 composite frame with 30% glass fiber eliminates harmonic distortion from the chassis itself. Buyers who want deeper sub-bass extension or higher overall output levels will need a dedicated subwoofer or larger component system.

Questions about this item

How does the 6.5" size affect fitment in my vehicle?

MB Quart engineers the PK1-116 to match factory mounting dimensions, so the 6.5" frame aligns with original speaker locations for a direct replacement in most compatible vehicles.

What does the 1" magnesium tweeter add to the sound?

The 1" magnesium dome tweeter uses WideSphere waveguide technology to widen high-frequency dispersion, creating a larger sound stage that can be aimed for better imaging.

What mounting depth and cutout does the composite frame require?

The PA66 frame with 30% glass fiber is designed to fit factory openings; the low-resonant construction reduces harmonic distortion without needing extra spacers or adapters.
