Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.897 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.269; 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 Rockville RVP12W8?

Load Forge's calculated alignment puts Rockville RVP12W8 in a 47.0 liter vented enclosure tuned to 46.0 Hz, reaching an F3 cutoff of approximately 67.6 Hz.

Can Rockville RVP12W8 be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 58.8 liters with a Qtc of 1.269 (above Butterworth: Qtc cannot fall below Qts (0.90)), the system exhibits an F3 of 61.7 Hz.

What port dimensions should be used for Rockville RVP12W8 to avoid port chuffing?

Sized from cone displacement (Sd × Xmax), a minimum port diameter of 10.0 cm with a length of 16.5 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
