Comparable 6.5" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Pride SL300.NEO65COMP 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
- Xmax is not published, so the port size is an empirical estimate (area ≥ 12 in² per ft³ of net volume, minimum by driver size), not a displacement calculation. Check air velocity in Load Forge Studio.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Pride SL300.NEO65COMP?
A simple ported box is not recommended for Pride SL300.NEO65COMP: the textbook alignment (1.5 liters tuned to 354.0 Hz) needs a 5.4 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 Pride SL300.NEO65COMP be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.16 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 528.1 Hz.
What port dimensions should be used for Pride SL300.NEO65COMP to avoid port chuffing?
A straight 10.0 cm port would need 5.4 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
