resonant enginnering sx vs xxx

[don makaveli]

ive came to the conclusion that i will be going wit either 2 12" re sx subs or 2 12" re xxx subs. can anyone help me out and tell me which ones they believe are better for the money. ive heard that sx's get louder then the xxx's but don't have as good of sq. I would like a system that is 60% spl and 40% sq

[f-onefity]

I would get SX's just from the cost difference, if sq is worth that much more to you, then go for the XXX's. Plus your not gonna need 3000+rms for 2 sx's.
