SUITS INFINITE / OPEN BAFFLEWith Qts 1.96 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 2.772; 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 Visaton DL 17 8 OHM?
Load Forge's calculated alignment puts Visaton DL 17 8 OHM in a 12.8 liter vented enclosure tuned to 63.8 Hz, reaching an F3 cutoff of approximately 105.5 Hz.
Can Visaton DL 17 8 OHM be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 16.0 liters with a Qtc of 2.772 (above Butterworth: Qtc cannot fall below Qts (1.96)), the system exhibits an F3 of 89.9 Hz.
What port dimensions should be used for Visaton DL 17 8 OHM to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 7.7 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
