⚠️ Engineering Notice for Builders
- Straight vent would be 1782.5 cm long: not physically buildable as a simple tube. Use a passive radiator, a folded slot port or model a 3D folded duct in Load Forge Studio.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for GS Audio Subwoofer Gs Audio Silver 6500 D 2ohm?
A simple ported box is not recommended for GS Audio Subwoofer Gs Audio Silver 6500 D 2ohm: the textbook alignment (3.6 liters tuned to 50.3 Hz) needs a 1782.5 cm port, and no nearby retune stays buildable without a bass hump. A sealed box, a passive radiator or a folded duct is the practical choice.
Can GS Audio Subwoofer Gs Audio Silver 6500 D 2ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 1.8 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 96.3 Hz.
What port dimensions should be used for GS Audio Subwoofer Gs Audio Silver 6500 D 2ohm to avoid port chuffing?
A straight 26.4 cm port would need 1782.5 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
