Subwoofer box calculation?

[LinusHenriksson]

Hello. Got some old subwoofers, a pair of legacy lw1230p. Sooo i wanted to make a good box to match these subs, but then i realized i have no idea how. Could anyone please explain this to me or give me a good size? Ported/closed box? Ill be thankful forever if you give me some help..

Heres the specs i found for it, can't find any box recommendations or anything else

• 12" Poly Resin Laminated Woofer
• 30 oz Magnet
• 1 1/2" High Temp Aluminum Voice Coil
• Frequency Rage - 30Hz - 4 kHz
• 75 Watts RMS
• 150 Watts Peak
• 4 Ohm

Sell those things as fast as you can. Even at $40 you can find much better than those.
