First build log. :emb:

I finally pulled the trigger and decided to try to build my first 4th order bandpass. I plan to have it ported thru the rear armrest,but that will depend on how this comes out and sounds.

The Design

Got the idea from a build log I seen. 3^ft P / 2^ft S @ 50hz for 2 12's. I plan to paint the inside and put plexi on the back side if the paint comes out good.

Countersinking FTW!


Thats it so far. This is by far the most time I spent on a box ever,hell I never even predrilled before. :crazy: But patience is the key with this build, as I want to get the sanding and painting perfect.
Even if the paint come out terrible out and it just sounds like yesterdays trash,its been one hell of a learing experience, learned many tricks of the trade. ;)

stay tuned.

I couldnt figure out no other way to design the sub/port with my dimensions other then this way.
