Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Visaton WS 13 E 4 OHM?
Load Forge's calculated alignment puts Visaton WS 13 E 4 OHM in a 5.7 liter vented enclosure tuned to 70.5 Hz, reaching an F3 cutoff of approximately 104.6 Hz.
Can Visaton WS 13 E 4 OHM be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 7.1 liters with a Qtc of 1.301 (above Butterworth: Qtc cannot fall below Qts (0.92)), the system exhibits an F3 of 94.9 Hz.
What port dimensions should be used for Visaton WS 13 E 4 OHM to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 33.6 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
