Comparable 10.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Dayton Audio RSS265HE-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
- Straight vent would be 250.6 cm long: not physically buildable as a simple tube. Use a passive radiator, a folded slot port or model a 3D folded duct in Load Forge Studio.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Dayton Audio RSS265HE-22?
A simple ported box is not recommended for Dayton Audio RSS265HE-22: the textbook alignment (16.4 liters tuned to 29.4 Hz) needs a 250.6 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 RSS265HE-22 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 7.1 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 56.4 Hz.
What port dimensions should be used for Dayton Audio RSS265HE-22 to avoid port chuffing?
A straight 12.5 cm port would need 250.6 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
