Hey all,
I’m new to the forum and diy audio world.
Recently I decided I wanted to build a tapped horn for my home theater room I’ve also just recently built in the basement. My original plan was to use some old (like 11-15 years old) car audio subs I had laying around from when I was 16. Jl audio 12w0-8. So I stumbled around the internet looking for 12” tapped horn plans. I seen lilmikes builds pop up everywhere but couldn’t find much for a 12” sub and I don’t have the space for a refrigerator sized box (Haha).
Enter the cubo12. The cubo looked a little different than most tapped horns I’d seen with regards to the chamber the sub fires into, it seemed larger. Where most the tapped horns fired into a very small chamber.
So I built the box using Baltic birch plywood and PL for glue. I used a plate amp out of an old energy sub I picked up for like $30.
When I tested the box I noticed I was getting a weird rattling noise. The sound seemed like it was mechanical so I swapped out for my other 12w0-8 I had laying around, still made the same noise. At that point I figured maybe it was because they were so old and not in the greatest shape. Yesterday I ended up going out and buying a new Rockford Fosgate P1 to put in the box. I got it all mounted last night and tested it out....same thing! I’m at a loss as to what would be causing this noise. Would an air leak cause this? Maybe the amp? Or is this box just trash? Any help would be appreciated.
