Comparable 5.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Dayton Audio MX5-22 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
- The textbook alignment (6.5 L at 40.4 Hz) would need a 51.9 cm port; the recommendation is retuned to 6.5 L at 44.4 Hz so the port can be built.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Dayton Audio MX5-22?
Load Forge's calculated alignment puts Dayton Audio MX5-22 in a 6.5 liter vented enclosure tuned to 44.4 Hz, reaching an F3 cutoff of approximately 41.2 Hz.
Can Dayton Audio MX5-22 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 2.9 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 75.0 Hz.
What port dimensions should be used for Dayton Audio MX5-22 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 42.4 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
