Premium coaxial speakers

Two pairs of MB Quart PK1-169 6x9-inch coaxial speakers are supplied new for car-audio upgrades. Each speaker uses a two-way design with a dedicated tweeter for clearer high-frequency output. The bundle includes a Creative Audio coozy as an extra item.

WideSphere waveguide tweeter

A 1-inch magnesium dome tweeter sits inside a tunable waveguide housing with a removable phase lens. WideSphere technology shapes off-axis dispersion to widen the sound stage and lets the listener aim the imaging. Tight-tolerance crossover components direct frequencies cleanly between drivers.

Lightweight mica-blend cone

Aerated pop paper cones with a mica blend deliver strength and superior bass reproduction without adding mass. The PA66 composite frame with 30% glass fibre suppresses harmonic distortion from the mounting surface. Buyers needing separate component sets or larger subwoofer integration will need different products.

Questions about this item

How does the 6x9 inch size affect fitment in a real car door?

The 6x9 inch dimensions are designed to match factory openings in many vehicles, and the aerospace-grade PA66 composite frame with 30 percent glass fiber keeps the mounting depth consistent for a direct fit.

What does the coaxial design mean for the tweeter and woofer alignment?

The 1-inch magnesium dome tweeter is centred on the lightweight aerated pop paper cone with Mica blend, so high and mid-bass frequencies originate from the same point for coherent imaging.

What mounting hardware or adapters are needed to install these speakers?

The low-resonant PA66 composite frame uses the standard 6x9 bolt pattern, so most installations only require the factory screws; no extra adapter rings or spacers are specified.
