MB Quart XK2-169 6x9" 2-Way Coaxial Speakers

The MB Quart XK2-169 is a pair of 6x9-inch, 2-way coaxial car speakers intended for upgrading compatible factory or aftermarket vehicle speaker locations. It combines the woofer and high-frequency drivers into each speaker assembly, providing a space-efficient full-range replacement option. The published 150-watt RMS and 300-watt peak power ratings apply per pair.

These speakers are suited to listeners who want to replace worn factory 6x9-inch speakers or build a straightforward aftermarket system around a compatible head unit or external amplifier. Their 88 dB sensitivity and published 55 Hz-22 kHz frequency response describe their operating range and efficiency rating. Vehicle fitment should always be confirmed against the available mounting opening and depth before purchase.

The XK2-169 is specified as a 2-way coaxial system, placing multiple drivers within the same 6x9-inch speaker footprint. This format can simplify an upgrade where separate tweeter locations or external crossover mounting are not desired. It is designed for use in automotive audio applications.

Published crossover information lists 12 dB slopes at 1 kHz and 3 kHz. This crossover design is intended to divide frequency reproduction among the drivers in the coaxial assembly. Pairing the speakers with properly matched amplification and clean source signal is important for practical system setup.

For installation planning, the published cutout requirement is 8.64 by 5.98 inches, with a mounting depth of 3.35 inches measured from the flange. These measurements are useful starting points, but door panels, rear decks, grilles, adapters, and window mechanisms can vary by vehicle. Confirm clearance, mounting-hole alignment, and wiring polarity before installation.

Design & Installation

The XK2-169 uses a coaxial speaker layout in a nominal 6x9-inch frame. MB Quart describes the speakers as constructed with high-quality materials, though specific cone, surround, voice-coil, and magnet materials are not publicly confirmed for this exact model. The integrated-driver design is intended to keep the installation concentrated in a single speaker opening.

Check that the vehicle supports a 6x9-inch replacement speaker and verify the published 8.64 by 5.98 inch cutout and 3.35 inch flange-depth requirement against the actual location. Use appropriate vehicle-specific brackets, wiring adapters, and fasteners where required; these items are not confirmed as included. Match the source or amplifier output appropriately to the speaker system and observe correct positive and negative terminal polarity during wiring.
