Our contemporary service has been using a jimmy-rigged system since I got there in 2010 and I am trying to slowly tweak it. It's time to look at the speakers. Currently we're using two JBL powered 1x15's on tripods at stage left and right, two passive Yorkville 1x15's flown center stage angled outward left and right, and a passive homemade 2x15 subwoofer that sits stage right and sounds awful. The JBL's are getting full range coming from the stereo sends from the board (Studiolive 24.4.2). The mono send is going to a crossover and splitting the highs to the flown Yorkvilles and the lows to the sub. Our service is held in our gymnasium. The stage is built into the wall on the side in the center, and we have these two HUGE thick curtains that are on motorized tracks that split the gym into thirds, and we play to the middle third. This really helps the sound a lot and it doesn't sound like a gym, but rather a small club. We seat about 250 chairs. My goal was to invest in the new Yamaha DSR system. I was planning to get two DSR 118 powered subs for stage left and right, using them with the JBL's, until I can replace them with two DSR 215 powered mains stacked on the subs. I'm at the point where it's time to get the subs, but I'm taking a last minute look around to see if there's anything better for my money. I've already A/B'ed the DSR's next to JBL's powered series, and the Yamaha's blow them out of the water, so I don't want the JBL's. I came across Carvin's LS series. They have powered 118 subs for half the price of the DSR's ($499 vs. $999). The only diff I see is the DSR's are 800w and the LS series is 700w. Not sure how much a difference that is. All the reviews of the LS series seem to be good. Anyone with experience with these?
