I love'em honestly but it really is a matter of preference to what you like your sounds to sound like,it is definately worth trying you just might wanna make sure the person who builds the box doe's it for the love of the sounds and not the love of the money. I can definately believe that ryno, i saw a guy with 4 alpine type r's in a chevy caprice with 4 of the alpine 1000's interlinked running to them in a slot ported box and let me tell you i sat in the car for maybe a total of 45 seconds before i started feeling sick to my stomach,so yeah i can definately say slot ported doe's do wonderful as well as circle ports and sealed.
