As previously mentioned the
DIYMA is a great sounding driver. If you have at/under 500 watts and mounting depth isn't an issue (probably isn't seeing as how you're running DD's) the
DIYMA is a very solid option. And as bass lover1 mentioned, the Mag v4 is a bit more durable and can handle up to 1000 watts. You can port the
DIYMA where you can't port the Mag, but both drivers have their areas/situations where they are better suited. Neither of which are a bad choice for going the "SQ" route. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif But with both of those drivers, get ready for a massive decrease in output. You're going from two DD 12's (ported I assume) to one small box 12".
