Maybe he changed his mind. That's the last I heard. Do you have a link? I never can find specs on their website.The website says anywhere between 30-40 hz tune and .6 -1 cubic foot enclosure
reconing is your friendso maybe i will just keep my type -r and get a bigger amp for it when i get my componets for up front. My issue with the type-r is i feel like im missing some frequencys i feel it should be picking up better particulary the lower ones. I had a mb quart reference series before this( you know the all black ones with inverted suround made by fosgate for mbq) anyways and it was awesome on the lows and sound quality was better untill it blew the voice coil. I loved that sub!
