⚠️ Engineering Notice for Builders

Port length (61.3 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.

Sealed (Acoustic Suspension) — compromise

SUITS INFINITE / OPEN BAFFLE

With Qts 0.804 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.137; 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 PowerBass S-10TD?

Load Forge's calculated alignment puts PowerBass S-10TD in a 16.7 liter vented enclosure tuned to 31.4 Hz, reaching an F3 cutoff of approximately 46.1 Hz.

Can PowerBass S-10TD be used in a sealed box?

Yes. In a sealed (acoustic suspension) enclosure of 20.9 liters with a Qtc of 1.137 (above Butterworth: Qtc cannot fall below Qts (0.80)), the system exhibits an F3 of 43.6 Hz.

What port dimensions should be used for PowerBass S-10TD to avoid port chuffing?

Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 61.3 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.

Not sure if S-10TD 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.
