Comparable 2.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Peerless OX32SC00-08 does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- Straight vent would be 1.1 cm long: not physically buildable as a simple tube. Use a passive radiator, a folded slot port or model a 3D folded duct in Load Forge Studio.
- Limited linear excursion (Xmax: 1.05 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

SUITS INFINITE / OPEN BAFFLEWith Qts 1.1 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 1.556; 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 Peerless OX32SC00-08?
A simple ported box is not recommended for Peerless OX32SC00-08: the textbook alignment (1.5 liters tuned to 637.5 Hz) needs a 1.1 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 Peerless OX32SC00-08 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.016 liters with a Qtc of 1.556 (above Butterworth: Qtc cannot fall below Qts (1.10)), the system exhibits an F3 of 873.0 Hz.
What port dimensions should be used for Peerless OX32SC00-08 to avoid port chuffing?
A straight 20.0 cm port would need 1.1 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
