⚠️ Engineering Notice for Builders

The textbook alignment (40.0 L at 32.5 Hz) would need a 26.0 cm port; the recommendation is retuned to 50.0 L at 22.8 Hz so the port can be built.

Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.84 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.188; 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 HSW12CARBONO?

Load Forge's calculated alignment puts Hinor HSW12CARBONO in a 50.0 liter vented enclosure tuned to 22.8 Hz, reaching an F3 cutoff of approximately 43.7 Hz.

Can Hinor HSW12CARBONO be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 50.1 liters with a Qtc of 1.188 (above Butterworth: Qtc cannot fall below Qts (0.84)), the system exhibits an F3 of 44.5 Hz.

What port dimensions should be used for Hinor HSW12CARBONO to avoid port chuffing?

Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 37.0 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.

Not sure if HSW12CARBONO 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.
