Comparable 2.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the REDCATT DR-2-002-16R-B2-C0001 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
- Limited linear excursion (Xmax: 1.2 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for REDCATT DR-2-002-16R-B2-C0001?
Load Forge's calculated alignment puts REDCATT DR-2-002-16R-B2-C0001 in a 1.5 liter vented enclosure tuned to 133.4 Hz, reaching an F3 cutoff of approximately 121.7 Hz.
Can REDCATT DR-2-002-16R-B2-C0001 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.25 liters with a Qtc of 0.962 (above Butterworth), the system exhibits an F3 of 190.6 Hz.
What port dimensions should be used for REDCATT DR-2-002-16R-B2-C0001 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 18.5 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
