Comparable 10.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Audio System M 10 EVO2 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
- Xmax is not published, so the port size is an empirical estimate (area ≥ 12 in² per ft³ of net volume, minimum by driver size), not a displacement calculation. Check air velocity in Load Forge Studio.
- Port length (92.0 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Audio System M 10 EVO2?
Load Forge's calculated alignment puts Audio System M 10 EVO2 in a 38.4 liter vented enclosure tuned to 30.8 Hz, reaching an F3 cutoff of approximately 30.7 Hz.
Can Audio System M 10 EVO2 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 17.2 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 91.5 Hz.
What port dimensions should be used for Audio System M 10 EVO2 to avoid port chuffing?
Xmax is not published for Audio System M 10 EVO2, so the port is an empirical estimate: a 12.5 cm diameter with a length of 92.0 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
