1st time i've had anyone say anything about my port and now everyone on it and i don't see a problem.. as far as fu look at the sub man other subs in the $150 price range are like rf p3 sq, hdS3.1 the fu is much more sub for the $.. i wanted sq but 6 peeps here said they don't play below 38hz scared me off., also as i said popwar and others have fu subs have no problems new one is perfect.. if it hadn't gone on sale right as i sold mine i woulda got idq, xfl or 2 alpine s 12's wanted 2 but then i'd have to get another box, easier to stick with 1 and 750 was on sale.. i had given up on fu end of last year and darth got one and sorta talked me into it, cause his sounded so good., now he's got his wolfram and he's not even here much.. he's on fb though.. i don't see why peeps hating on fu so much, few glue issues even sundown, sq and others have had that problem..
