MB Quart Rear Coaxial Speakers Upgrade for 21-24 Ford Bronco, 6.5" Speaker Pods - 427498

Enhance the rear soundstage of your 2021–2024 Ford Bronco with the MB Quart Rear Coaxial Speakers Upgrade, an audio package engineered to deliver clearer highs, fuller mids, and a richer overall listening experience. Designed specifically for the Bronco’s rear pillar locations, this system replaces the factory speakers with high-performance 6.5" coaxial drivers that dramatically elevate rear audio output without altering the vehicle’s interior.

Each speaker features a 6.5" midrange driver paired with a 1" magnesium dome tweeter, delivering a balanced blend of warmth, accuracy, and crisp high-frequency detail. Thanks to MB Quart’s WideSphere Tweeter Technology, the tweeters provide wide dispersion, ensuring rear passengers experience more immersive, evenly distributed sound. Whether you're listening to music, podcasts, or navigation prompts, audio becomes more lifelike and engaging from every seat.

Behind the scenes, a 12 dB midrange crossover and 6 dB tweeter network ensures smooth frequency transitions and clean separation, preventing distortion while preserving clarity. With a frequency response of 55 Hz to 22 kHz, 88.5 dB sensitivity, and power handling of 110W Max / 55W RMS, these speakers deliver impressive performance, tight midbass, detailed vocals, and bright, accurate highs.

Installation is simple and vehicle-friendly. The custom rear pillar speaker enclosures are designed to mount directly in place of the OEM units, preserving a factory-finished look. With included OEM-style adaptor plugs, the speakers integrate cleanly into the Bronco’s wiring system, making the upgrade quick, secure, and modification-free.

Perfect as a standalone enhancement or as part of a full MB Quart audio system, the Rear Coaxial Speakers Upgrade brings clarity, power, and precision to your Bronco, ensuring every ride sounds as exciting as the adventure ahead.
