The Dayton Audio MX6-22 is a 6.5-inch (16.5cm) subwoofer driver designed to deliver remarkable performance in compact enclosures, whether for home HiFi, car audio, or custom installations. Featuring a dual voice coil architecture rated at 2Ω + 2Ω, it offers great wiring flexibility to suit a wide range of amplifiers. Its long-excursion motor combined with a low 30Hz resonant frequency enables it to produce powerful, deep bass despite its compact size. Its paper cone is reinforced by a full-surface concave dust cap, while the high-excursion rubber surround ensures long-term reliability. The MX6-22 incorporates a 38mm four-layer copper voice coil wound on a vented aluminum former, a ferrite magnet motor, and an aluminum shorting sleeve designed to reduce inductance variations and distortion. Its precision-stamped steel frame features a fully vented architecture with a pole vent and gap vents to optimize cooling. With a power handling capability of 70W RMS (140W max), a sensitivity of 83dB (2.83V/1m), a maximum linear excursion (Xmax) of 12mm, and a frequency response extending from 20Hz to 1000Hz, the MX6-22 is an ideal solution for building compact high-performance subwoofer enclosures.

Despite its modest 6.5" diameter, the MX6-22 is capable of reproducing deep bass thanks to its long-throw motor and substantial 12mm linear excursion. Its 30Hz resonant frequency, high 12.3Tm force factor, and low Qts of 0.33 allow it to perform efficiently in small sealed or bass-reflex enclosures. Its dual 2Ω + 2Ω voice coils provide multiple wiring configurations to optimize compatibility with a wide range of amplifiers.


The Dayton Audio MX6-22 benefits from a particularly refined mechanical design. Its paper cone is paired with an inverted dust cap covering the entire diaphragm to improve rigidity while giving it a modern appearance. The reinforced rubber surround ensures durable operation under high excursion. The four-layer copper voice coil wound on a vented aluminum former, combined with vents around the spider, the central pole vent, and the air-gap openings, promotes excellent heat dissipation and limits power compression during prolonged use.
The magnetic motor of the MX6-22 has been engineered to maintain symmetrical driving force throughout the cone travel, ensuring excellent linearity even at high output levels. An integrated aluminum shorting sleeve stabilizes voice coil inductance and reduces distortion across the entire frequency range. This design contributes to precise, dynamic, and tightly controlled bass while facilitating seamless integration with main speakers in HiFi, home theater, or automotive audio systems.
