Well, I got impatient... as some of you might know ive been having bass dilemas for a while, trying to choose what type of enclosure for my sub. So being impatient I just grabed an old 15" PA speaker that my brother used in his band and hooked that up as my sub. WOW, it was like having a bass drum right behind you and someone was stomping on it as hard as they could. impressive db's but thats about it and it hurt my ears. Well I couldnt stand it anymore. I cut a new front for the box and made holes for my 2 x 10" sub speakers Ive had for a while. Well the box was about 4 cubic feet or about 112 cubic liters. [i hope that conversion is right] It is an old box so im sure it isnt 100% sealed but I am pumping a max of 120 watts per speaker so I dont need to fix it up much more. besides, this is a temporary run. I just wanted to see how a large sealed box would do. My impression? why didnt I do this months ago!!!It sounds incredible!I went thru all my Cd's trying the low bass tracks and grinning the whole time!!! I did the Phantom Menace Pod race/THX test. I couldnt be happier Ill see if I can grab a RatshaQ meter this week and do some tests. maybe ill post pics if I can get a digi cam PS, the box faces the back of my couch and sits on 4 tennisballs to keep it off the carpet. any idaeas suggestions would be appreciated.
