So 10's would be pretty close to 12's? Or is it worth the cost increase to go with 12's. And yeah I know ported would be far more efficient, but I just don't have the hatch space to do that, I could do 4+ cubic feet if I wanted to, but I'm currently down sizing my 3.2 cubic box to 2.4 feet give or take so I can have it flushed. So ported I could do, but I paid so much already for my fiberglass work that I rather keep it, it's just the mdf being restructured. Besides my car is small inside, ported would be overkill on my mids and highs lol. I want this to be lsq. But thanks, I'm glad to know 10's are better than many other 12's I may just keep my 10 size then. Damn I wish I had 12 inch opening on my fiberglass, the speakers themselves are only 10 bucks more.
