My advice on the ported 10w6v2. I agree the w6v2 subs are the most natural sounding subwoofer I have ever heard and they do get pretty loud.. But take my advice for what it is worth.. I feel it is a crime to put the w6v2 in a ported box.. I built one to jl specs and It was Really loud(2 12w6v2) But to me it sounded like any other 12 in a ported box... That natural sound was gone.. But DAM>> it was Loud...I had two of them off of one 500/1 jl amp.. Well I am just voiceing my opinon(I am very pickey about sound quality) Dont get me wrong they sound good ported, but not even close to how they sound sealed.. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
