I dont know man, i always thought Diamonds were a lower name brand and never gave much thought into them until dalton showed me what they were capable of.

I finally removed my polks from my car and switched to 2 D6 12's.... never looked back, the xmax is decent, the power capabilities are more than sufficient and it plays pretty much the whole spectrum very clean...

but i know you've probably had your fill on diamonds toby... just my opinion



as far as the brands you mentioned, i've heard a few negative things on OZ, as far as the clarity. But from what i experienced was different, it was loud and rather good.

I'd really like to hear those other setups though, i've never even heard of the last brand you mentioned -- Critical mass?
