Dayton Audio MB620-8 Midbass Woofer

The Dayton Audio MB620-8 Midbass Woofer delivers a commanding presence in any sound system, combining robust construction with exceptional acoustic performance. Designed as a dedicated bass mid-bass subwoofer, this 6.5-inch driver excels at reproducing the critical midbass frequencies that give music its punch and impact. Whether you are building a high-fidelity home audio setup, a custom car audio installation, or a professional studio monitor, the MB620-8 provides the foundation for a rich, dynamic listening experience.

At the heart of this woofer lies a paper cone membrane, chosen for its natural damping properties and ability to deliver a warm, articulate sound. With a sensitivity of 94 dB (1m/2.83V), it offers efficient sound reproduction, requiring less amplifier power to achieve high output levels. The total Q factor (Qts) of 0.55 strikes a versatile balance, making the driver suitable for both sealed and ported enclosures, while the 0.93 mH voice coil inductance ensures controlled high-frequency roll-off. A 2 mm maximum linear excursion (Xmax) allows for clean, distortion-free bass at moderate volumes, and the robust 5.47 ohm DC resistance ensures stable operation. With a nominal diameter of 165.1 mm and a mounting depth of 80 mm, this woofer fits neatly into standard enclosures, while the four mounting holes and 147.3 mm cutout diameter simplify installation. The CCA voice coil wire offers reliable thermal performance. Combining high sensitivity with flexible enclosure design, the MB620-8 is a superb choice for anyone seeking authoritative midbass with effortless efficiency.
