Comparable 2.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Dayton Audio DMA58-4 does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- Limited linear excursion (Xmax: 2.0 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Dayton Audio DMA58-4?
A simple ported box is not recommended for Dayton Audio DMA58-4: the textbook alignment (1.5 liters tuned to 142.6 Hz) needs a 15.7 cm port, and no nearby retune stays buildable without a bass hump. A sealed box, a passive radiator or a folded duct is the practical choice.
Can Dayton Audio DMA58-4 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.096 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 257.1 Hz.
What port dimensions should be used for Dayton Audio DMA58-4 to avoid port chuffing?
A straight 5.0 cm port would need 15.7 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
