⚠️ Engineering Notice for Builders

  • Limited linear excursion (Xmax: 3.0 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.99 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.4; 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 10 CITY?

A simple ported box is not recommended for Hinor 10 CITY: the textbook alignment (27.5 liters tuned to 40.7 Hz) needs a 9.3 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 10 CITY be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 34.4 liters with a Qtc of 1.4 (above Butterworth: Qtc cannot fall below Qts (0.99)), the system exhibits an F3 of 55.5 Hz.

What port dimensions should be used for Hinor 10 CITY to avoid port chuffing?

A straight 5.0 cm port would need 9.3 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
