Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Coast Buyouts 10" 1025 Ribbed Paper Cone Woofer 8 ohm?
A simple ported box is not recommended for Coast Buyouts 10" 1025 Ribbed Paper Cone Woofer 8 ohm: the textbook alignment (96.1 liters tuned to 29.7 Hz) needs a 3.4 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 Coast Buyouts 10" 1025 Ribbed Paper Cone Woofer 8 ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 120.2 liters with a Qtc of 2.233 (above Butterworth: Qtc cannot fall below Qts (1.58)), the system exhibits an F3 of 40.3 Hz.
What port dimensions should be used for Coast Buyouts 10" 1025 Ribbed Paper Cone Woofer 8 ohm to avoid port chuffing?
A straight 5.0 cm port would need 3.4 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
