Comparable 6.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Fostex W160A-HR 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 Fostex W160A-HR?
Load Forge's calculated alignment puts Fostex W160A-HR in a 7.0 liter vented enclosure tuned to 51.7 Hz, reaching an F3 cutoff of approximately 54.2 Hz.
Can Fostex W160A-HR be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 3.2 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 95.5 Hz.
What port dimensions should be used for Fostex W160A-HR to avoid port chuffing?
Xmax is not published for Fostex W160A-HR, so the port is an empirical estimate: a 5.0 cm diameter with a length of 27.9 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
