Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.75 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.061; 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 BRAX CB22610?

Load Forge's calculated alignment puts BRAX CB22610 in a 11.6 liter vented enclosure tuned to 52.7 Hz, reaching an F3 cutoff of approximately 74.2 Hz.

Can BRAX CB22610 be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 14.5 liters with a Qtc of 1.061 (above Butterworth: Qtc cannot fall below Qts (0.75)), the system exhibits an F3 of 71.2 Hz.

What port dimensions should be used for BRAX CB22610 to avoid port chuffing?

Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 14.7 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
