Well Im soon to be buying a 10" subwoofer possible 8" and most likely I will end up buying a 10" and a 8" to see which one I like better. I have been looking around for quite some time now and pretty much got 2 in mind. The IDQ and the rl-i. Does any one have any other suggestion for a sq 10" that is preferably around 500rms but does not have to be this high(i.e. IDQ)
