Comparable 3.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker 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
- The textbook alignment (1.5 L at 153.0 Hz) would need a 13.2 cm port; the recommendation is retuned to 3.8 L at 137.7 Hz so the port can be built.
- 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 Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker?
Load Forge's calculated alignment puts Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker in a 3.8 liter vented enclosure tuned to 137.7 Hz, reaching an F3 cutoff of approximately 123.3 Hz.
Can Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.57 liters with a Qtc of 2.984 (above Butterworth: Qtc cannot fall below Qts (2.11)), the system exhibits an F3 of 210.1 Hz.
What port dimensions should be used for Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker to avoid port chuffing?
Xmax is not published for Factory Buyouts LG EAB33496904 1-5/8" x 4-1/2" Full-Range Paper Cone Speaker, so the port is an empirical estimate: a 5.0 cm diameter with a length of 4.6 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
