The Yamaha DXS subs are pretty decent for compact subs if you’re trying to stick to one brand. Really wish Yamaha made a killer 2x18. Would compliment the DZR line nicely.
I'll second that. Would love it if they had a 218 in the DZR line.
OP, you can't go wrong with the Yamaha DSR/DZR stuff. It really lives up to the hype. I'd also consider the older QSC HPR line if you can get a great deal on it. Although it's heavy, that older HPR stuff worked and sounded great.
I haven't been very impressed with EV's powered stuff. I mean, its OK, but it just doesn't stand out as great. Same with the newer JBL stuff too. Yamaha is killing it in this market. The stuff Yamaha puts out in the MI market is as good as some of the higher end dealer-only systems you pay a whole lot more money for.
