SUITS INFINITE / OPEN BAFFLEWith Qts 0.71 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.004; 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 Skar Audio IX-10 D4?
Load Forge's calculated alignment puts Skar Audio IX-10 D4 in a 22.4 liter vented enclosure tuned to 31.8 Hz, reaching an F3 cutoff of approximately 46.7 Hz.
Can Skar Audio IX-10 D4 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 28.0 liters with a Qtc of 1.004 (above Butterworth: Qtc cannot fall below Qts (0.71)), the system exhibits an F3 of 46.1 Hz.
What port dimensions should be used for Skar Audio IX-10 D4 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 43.2 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
