I'm planning on getting either a 15" or 18" sub that will take ~1k rms daily. I need some companies who make affordable 18's that can perform like this. Please give me some names of who to check out for either 15's OR 18's, but preferably 18's And I know the popular (around here) companies like DC, DD, AA etc so no need to name them... I've looked at Obsidian (but I don't want to wait forever to get one), Sundown, AQ...I don't plan on spending over $250ish.....
