I think Marshall will agree with me on this one... Go with a single 15" SX and pick up the RE 12.1 to match it. If you build your box right (4-6ft^3 tuned 30-35hz) it will be louder than you can handle. 6000w or even 3000w for that matter is overkill, IMO, for a daily setup. You can get VERY loud with 1000w. This setup will save you money in subs, amps, wires, and most importantly charging equipment.
^ i agree but instead of using the sx mabey use the ti, i heared that they get very loud also, and plus i think it would be cool seeing a sub that has like 2inchs of excursion.
for $240 shipped, you can't beat the SX. I don't know which would be louder though, probably very similar. as far as excursion, that does not determine your output or sq. but yea, it is cool
ya the sx costs $240 shipped and the ti is over $300 so price can play a role also, but if you don't have a lot of room the ti might be better cause they require a small box.
Overall, I'd go for the Tis. 2 10 or 12 inch Tis, especially ported, would get ridiculously loud anyway. Unless you're a competitor you really wouldn't want more out of a system.
