Comparable 1.5" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Punktkilde AUGDL0003-JN05_0 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: 0.2 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.
Textbook Bass Reflex — not recommended (12.8 dB bass hump)

SUITS INFINITE / OPEN BAFFLEWith Qts 2.1 a Butterworth (Qtc 0.707) box would be many times Vas. A box equal to Vas reaches Qtc 2.97; 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 Punktkilde AUGDL0003-JN05_0?
A simple ported box is not recommended for Punktkilde AUGDL0003-JN05_0: the textbook alignment (1.5 liters tuned to 557.6 Hz) needs a 5.9 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 Punktkilde AUGDL0003-JN05_0 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.011 liters with a Qtc of 2.97 (above Butterworth: Qtc cannot fall below Qts (2.10)), the system exhibits an F3 of 798.7 Hz.
What port dimensions should be used for Punktkilde AUGDL0003-JN05_0 to avoid port chuffing?
A straight 20.0 cm port would need 5.9 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
