Hey peoples, I have know decide with holidays, to build a new box for my Pioneer ts121spl sub.

Now i know the sub is SPL oriented, but im sure its possible for it too sound good too right? I want to build a box for it, which is aimed at sound quality.

Its running of a jaycar 2x150rms amp, which may be upgraded to a j-car monobloc.
Anyway ive tried all those box building programs like winISD etc. but cant figure it all out. Im wondering if someone can help me out with this part of the build, and possible give me the dimensions needed.

Now another thing im thinking is ported or sealed. I know the difference but i do want the sub to be capable of going loud still. So im headed towards ported box, is it capable of sounding good?

Sub Specs Here

any advice, on size MDF to use etc. I also want to put a sheet of perspex (summin the like) on the back so i can see the basket of the sub.

thanks again guys/gurls

Also, the perspex wont cover the whole back of the box, i will just cut a piece of MDF out and put the perspexs on.
