Comparable 10.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Rockville RXM108 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.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Rockville RXM108?
Load Forge's calculated alignment puts Rockville RXM108 in a 33.9 liter vented enclosure tuned to 54.4 Hz, reaching an F3 cutoff of approximately 74.7 Hz.
Can Rockville RXM108 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 42.4 liters with a Qtc of 0.983 (above Butterworth), the system exhibits an F3 of 73.3 Hz.
What port dimensions should be used for Rockville RXM108 to avoid port chuffing?
Xmax is not published for Rockville RXM108, so the port is an empirical estimate: a 12.5 cm diameter with a length of 27.7 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
