My very old Magnat subwoofer stopped working recently, time to get something new. Butget should be under 500€, i made it in 280€.
Woofer:
Looking at different woofers and their prices, i found the Alpine SWG-1244, 4 ohm (80€). It's a 12" car subwoofer that seems to be happy in a small, closed enclosure.
Enclosure:
The enclosure is made from 26mm thick MDF, the box will be exactly 380x380x380mm. The material is solidly colored black, so there is no painting needed. The MDF was sent to me by an online service and the cost was 54€. I only have to make one cut for the speaker itself, and one for the terminal, with a jigsaw. I guess this can be done on the balcony. To connect the parts, i'll use wood plugs and glue.
Amplifier:
I'll use a Monacor SAM-300D plate amp. 300W into 4 ohm, class D, 140€, the usual active subwoofer knobs and connections. The amp will have a separate enclosure.
I don't have a speaker cable terminal yet, i guess i'll just drill a hole and stick some cable through for now.
Anything i didn't consider?
