Comparable 24.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Celestion TSQ2460 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
- Port length (64.5 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.
- Large enclosure volume (167.9 L) requires extensive internal matrix bracing to prevent panel resonance.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Celestion TSQ2460?
Load Forge's calculated alignment puts Celestion TSQ2460 in a 167.9 liter vented enclosure tuned to 33.2 Hz, reaching an F3 cutoff of approximately 34.8 Hz.
Can Celestion TSQ2460 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 77.5 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 62.5 Hz.
What port dimensions should be used for Celestion TSQ2460 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 25.5 cm with a length of 64.5 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
