Comparable 4.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the MISCO 100-WF08-01 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 (2.0 L at 63.8 Hz) would need a 68.7 cm port; the recommendation is retuned to 2.0 L at 79.8 Hz so the port can be built.
- 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.

SUITS INFINITE / OPEN BAFFLEWith Qts 0.95 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.344; for a flat response this driver is better used on an infinite (IB) or open baffle.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for MISCO 100-WF08-01?
Load Forge's calculated alignment puts MISCO 100-WF08-01 in a 2.0 liter vented enclosure tuned to 79.8 Hz, reaching an F3 cutoff of approximately 102.9 Hz.
Can MISCO 100-WF08-01 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 2.5 liters with a Qtc of 1.344 (above Butterworth: Qtc cannot fall below Qts (0.95)), the system exhibits an F3 of 88.1 Hz.
What port dimensions should be used for MISCO 100-WF08-01 to avoid port chuffing?
Xmax is not published for MISCO 100-WF08-01, so the port is an empirical estimate: a 5.0 cm diameter with a length of 42.6 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
