We don't really have a place for car audio and the speaker category would be closer than the car I would believe. Anyways I have a 12" Alpine Type R Model SWR-1243D I wanted to build a decent ported box for it. Parameters are Here
So I was just going to go with one of these, I've heard they like large boxes so I was going with the 2.5@32HZ, Does anyone have any advice on this. Any help is much appreciated. I'd rather go with plans to go by.
1) MDF Wood (1/2" inch minimum thickness, 3/4" inch maximum thickness)
2) Wood Glue (around 300mls)
3) A lot of screws (around a 100x) around 1" inch to 1 1/2" depending on thickness of MDF
As for porting I have found that small ports produce around a 2" diameter produce sharper louder bass kicks and larger 3 1/2" diameter or multiported 2" diameter ports produce lower bass tones with rumble and softer kicks.
Build the box according to the type of music you listen to and good luck with your project.
