Alpine Type R 12" Box Ported - Need Advice Please!


gbsx

Recommended Posts

So I built my first box about 2 months ago and it came out pretty shitty. I'm looking to build a new one. I finally got some decent tools in hand that will help me out.

My first one was 1.65 cubes tuned to about 33 hz but after all the bad cuts and small port it probably was no where near 33hz..

I need some advice on a new box.

Size, port tuning. How much port area?

I'm willing to pay a few dollars for a good design and a cut sheet with some details on the box.

It's just one 12" Alpine Type R (2009 model) so 500 RMS.

Any help is greatly appreciated!

Thank you,
