Comparable 6.5" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Ciare CW162 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 (4.4 L at 68.4 Hz) would need a 48.0 cm port; the recommendation is retuned to 4.4 L at 71.8 Hz so the port can be built.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Ciare CW162?
Load Forge's calculated alignment puts Ciare CW162 in a 4.4 liter vented enclosure tuned to 71.8 Hz, reaching an F3 cutoff of approximately 78.3 Hz.
Can Ciare CW162 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 2.5 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 116.0 Hz.
What port dimensions should be used for Ciare CW162 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 43.1 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
