A single speaker that fits both 5x7" and 6x8" factory openings, the MBQuart 2-Way Coaxial delivers aluminium dome clarity and a 2.13" mounting depth built for tight door cavities.
The MBQuart 5x7"/6x8" 2-Way Coaxial is engineered around a multi-fit basket that drops straight into the factory speaker openings found in Ford, Mazda and a wide range of other vehicles, eliminating the need for adaptor rings or custom brackets. A heavy gauge progressive-die stamped steel frame and ferrite magnet motor keep the assembly rigid and magnetically efficient without adding unnecessary bulk. Aluminium dome tweeters cross over at 6 kHz via a 12 dB slope, pairing with butyl rubber surrounds on the woofer cone for long-term durability in demanding environments. At just 2.13" deep, the speaker slides into shallow door cavities where full-depth units simply will not go, and flexible spade or solder connections with tinsel leads make installation straightforward in any configuration.
Three things that matter.
Genuine Multi-Fit Basket
One speaker, two opening sizes: the basket is engineered to seat correctly in both 5x7" and 6x8" factory cutouts, so a single part number covers a broad range of Ford, Mazda and compatible vehicles without adaptors.
2.13" Shallow Mounting Depth
At only 2.13" deep, the speaker fits door cavities that defeat conventional coaxials, making it a practical choice for vehicles with limited clearance behind the door skin.
Aluminium Dome Tweeter with Butyl Rubber Surround
The aluminium dome delivers crisp high-frequency detail, while the butyl rubber surround on the woofer resists UV, heat and moisture for reliable performance over the long term.
