SUITS INFINITE / OPEN BAFFLEWith Qts 0.77 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.089; 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 GF 200 - 2 x 4 Ohm?
Load Forge's calculated alignment puts Visaton GF 200 - 2 x 4 Ohm in a 49.6 liter vented enclosure tuned to 28.9 Hz, reaching an F3 cutoff of approximately 40.3 Hz.
Can Visaton GF 200 - 2 x 4 Ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 62.0 liters with a Qtc of 1.089 (above Butterworth: Qtc cannot fall below Qts (0.77)), the system exhibits an F3 of 38.8 Hz.
What port dimensions should be used for Visaton GF 200 - 2 x 4 Ohm to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 21.4 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
