Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.96 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.358; 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 Hinor HSW12CARBONOD4?

A simple ported box is not recommended for Hinor HSW12CARBONOD4: the textbook alignment (32.6 liters tuned to 35.0 Hz) needs a 27.8 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 Hinor HSW12CARBONOD4 be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 40.8 liters with a Qtc of 1.358 (above Butterworth: Qtc cannot fall below Qts (0.96)), the system exhibits an F3 of 47.8 Hz.

What port dimensions should be used for Hinor HSW12CARBONOD4 to avoid port chuffing?

A straight 7.5 cm port would need 27.8 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.

Not sure if HSW12CARBONOD4 fits your physical space?

Don't force a driver into the wrong box. Use Bass Match to calculate which of 8,000+ catalog drivers delivers the highest SPL, lowest F3, and cleanest port air velocity for your exact trunk or room dimensions.
