ok then, let me try this again, my name is jack and i am into car audio buying selling and tradeing..i come across stuff all the time thats how i got this eclipse subwoofer.i have used this sub myself for about a month and personally i think it hits harder than a jl 12w7 which i have had one of those too so i just compared and this sub did better in my opinion by far. which that suprised me because i am a very big jl fan.. i did deal with the guy that told me about this site and from what i hear some of you know him, i will be posting him as a refernece soon, as far as pics, send me an e mail address and ill send em to you because i dont know how to put them up in here...so thanks for your time and patience as i am new to thi s site..thanks again
