I cant say for sure, but I own a single 12w1v2 sealed......used to be ported, and it gets very loud for what it is. Im only pushing 170watts to one, and you would be very impressed with this entry subs output. It sounds great also. This is the replacement for the WOs everyone raved about, an this sub has a larger surround, larger motor and voicecoil, and has a rubber surround. Hope this helps some. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
