ok man alpine makes the type x and re makes sx.... u should have made that clear.. lol hummmmm..... i dont no the sx is for spl if im not mistaken but... like creater said... theres more cone area with the l7... id say go with wat u can get the cheapest //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i loved my SX i had, got really loud and sounded pretty good doing it, an L7 wouldnt sound as good as an sx but i dont know which is louder, 2 SXs would wang like crazy, 2 L7s would prolly be loud and sound "meh", i would choose 2 SXs if it was me
ive got my two l7's on a kx 1200.1 and i LOVE em. BUT ur going to really want to get a ported box and tune it around 32-34 Hz to get good spl for a daily driver. Also make sure u know which ohm loads you want on your voice coils before you buy em'.
