I was replacing the box and when I got the sub out and turned it over I saw the crack. That seems to be an issue with the e12a and why they don't make them anymore.
Thinkng about it, when I first got the 12a it was very punchy and tight. Lately it's been sloppy and boomy. It's time move on to better.
BTW, I don't plan on looking at every sub from 8-18 here. I'll spare the forum //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
