Dynavox 204204 Bass-midwoofer

The Dynavox 204204 Bass-midwoofer is a compact yet capable driver designed to deliver articulate bass and midrange performance in space-constrained applications. As a dedicated bass-mid-bass subwoofer, it excels in bringing clarity and definition to lower frequencies without demanding excessive enclosure volume, making it an ideal choice for audiophiles and DIY enthusiasts seeking to build high-quality, compact speaker systems.

This driver is perfectly suited for small to medium-sized sealed or ported enclosures, where its controlled response and modest power requirements allow for precise integration into bookshelf speakers, satellite systems, or even custom automotive audio projects. Its 4-ohm impedance simplifies system matching with a wide range of amplifiers and crossover networks, ensuring straightforward setup for both novice and experienced builders. With a maximum power handling of 20 watts, it pairs well with low-to-moderate power amplification, prioritising efficiency and sound quality over brute force.

Technically, the 204204 features a resonance frequency (Fs) of 99 Hz and a sensitivity of 84 dB SPL measured at 1 metre with 2.83V input, indicating a driver optimised for detailed reproduction rather than high output. Its mounting depth of just 44 mm and a screw circle diameter of 94 mm, secured by four mounting holes, allow for easy installation in shallow cabinets. The robust construction ensures reliable performance, making this Dynavox driver a practical and sonically rewarding component for discerning listeners.
