which one out of 4 diamond d3 or 4 jl w3 12 would be louder and hit harder in a ported box also what about six d3 12's in a sealed box one of these systems would be going into a 94 chevy caprice.
I would definitly rather have the diamonds. Ive got a single D3 10'' at 400 watts rms in a ported box built to diamonds specs. It gets very loud and sounds really good.
I am in the middle of building a box for my D9 10''.
I go for SQ over SPL anyday but, Diamond definitly pleases me in both categories.
