Overview

Built to sound
right.

A purpose-built 4x6" coaxial speaker for vehicles running smaller oval factory openings, combining an aluminium dome tweeter and butyl rubber surround in a heavy-gauge steel basket rated to 250W peak.

The MBQuart 4x6" 2-Way Coaxial is designed for direct replacement of the compact oval speakers found in many factory fitments, including the Toyota LandCruiser 70 Series dash and door positions. A ferrite magnet motor drives the woofer cone while the integrated aluminium dome tweeter handles the upper frequencies through a 12 dB crossover slope at 6 kHz. Butyl rubber surrounds resist cracking and UV degradation far better than foam alternatives, making these speakers well suited to the harsh Australian climate. Flexible tinsel leads and dual connection options, spade or solder, keep installation straightforward in tight factory cavities.

02

Three things that matter.

The details that decide how it actually sounds once it is installed.
Feature01

Aluminium Dome Tweeter

The aluminium dome tweeter delivers crisp, detailed high-frequency reproduction without the coloration introduced by softer dome materials, integrated directly into the coaxial assembly for a clean factory-style fit.

Feature02

Butyl Rubber Surround

Butyl rubber outlasts foam surrounds significantly, resisting heat, UV exposure and moisture, which is critical in the demanding environment of a working LandCruiser 70 Series cabin.

Feature03

Heavy-Gauge Progressive-Die Stamped Steel Frame

The rigid steel basket maintains precise cone geometry under high excursion, reducing distortion at elevated power levels and ensuring the speaker holds its alignment over years of corrugated-road use.
