Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Ciare PM200N 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: 3.5 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 Ciare PM200N?
Load Forge's calculated alignment puts Ciare PM200N in a 11.6 liter vented enclosure tuned to 77.6 Hz, reaching an F3 cutoff of approximately 81.5 Hz.
Can Ciare PM200N be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 7.7 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 137.2 Hz.
What port dimensions should be used for Ciare PM200N to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 10.7 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
