I've been thinking about it for a while but I now can't wait any longer to upgrade my sound system. There's nothing more fun than a sweet ride and a sweet stereo system to go with it!

Does anybody have any experience or have an idea if some Alpine SPR-57LS speakers are any good? I saw them at Best Buy - so, I am thus skeptical. However they were somewhat pricey and it was a whole set (tweeters + two speakers).

SPR-57LS

What I found really strange was they are listed as "5-7" AND "6-8". On the box!! And yet they compared the same in size to a 6-8". So I don't know how they fit in a 5-7. Interestingly, Best Buy has in their computer that the RX-8 takes two 6-8's in the front and two 6-8's in the rear. I've read on this forum that the rears are 6 by 9's...well which is it?

Thanks for the input!
