So, I'm in the market for a 15" to compliment my ampeg 810. I want options, and a 410, 115 and 810 seem like options. No tweeters. 4 ohm. ~350-500 watts? Price isn't an issue (woohoo!) I don't know if i want it ported or sealed as a compliment to the sealed 810. I've also never had a 15, i've played a few, wasn't able to pair it up with an 810 ever. I don't really know if the sealed would be the best choice in this situation to give me that bass low end. what would be the ideal cab? I'm getting serious gas being on these boards, and feel that this is next step for me. So, any input would be way helpful.
