MB Quart XK2-106 2.75" 2-Way Coaxial Speakers

The MB Quart XK2-106 is a compact pair of 2.75-inch coaxial 2-way speakers for car audio and powersports applications. It is designed for installations where available speaker space is limited but a full-range speaker upgrade is still needed. The package includes two speakers for use in a matched left/right or custom-system installation.

Its small footprint makes the XK2-106 suited to compact factory locations, custom panels, and other space-conscious vehicle audio projects. The 4-ohm nominal impedance supports use with compatible car-audio receivers or amplifiers. Before purchasing, confirm available mounting space and the load capability of the audio source.

The XK2-106 is rated for 70 watts RMS and 140 watts maximum power handling. Its published frequency response spans 55 Hz to 22 kHz, covering bass, midrange, and high-frequency content within a compact coaxial format. A 92 dB sensitivity rating supports efficient output when matched with an appropriate audio system.

A black aluminum dome tweeter is integrated into the coaxial speaker design to reproduce high-frequency detail from the same mounting location as the main driver. The speaker uses a steel basket for structural support. This combination is intended for vehicle environments where compact packaging and durable construction are important.

For a simple compact upgrade, the XK2-106 can be used where a small full-range speaker is required in a car or powersports audio system. Its coaxial 2-way layout keeps the woofer and tweeter together rather than requiring separate tweeter locations. Pair it with compatible wiring, mounting hardware, and a source unit or amplifier that is suitable for 4-ohm speakers.

Key Features

• 2.75-Inch Size: Fits compact speaker locations and custom installations.
• Coaxial 2-Way Design: Combines main-driver and tweeter output in one speaker.
• 70W RMS Handling: Supports continuous-power system matching.
• 140W Maximum Handling: Provides published peak power capacity.
• Black Aluminum Dome Tweeter: Handles the speaker's high-frequency reproduction.
• Steel Basket: Provides a rigid foundation for the speaker assembly.

Design & Installation

The XK2-106 combines a black aluminum dome tweeter with a steel basket in a compact coaxial speaker assembly. The 2-way layout places the high-frequency element within the same speaker structure as the primary driver. This design helps simplify placement where there is room for only one small speaker location.

Measure the factory opening, mounting depth, cutout, and panel clearance before ordering, as those dimensions are not published in the confirmed product information. Use suitable mounting hardware and connect each speaker with correct polarity to a compatible 4-ohm receiver or amplifier channel. The pair is intended for car and powersports audio installations; confirm that the chosen location is appropriate for the vehicle and installation conditions.
