Hi guys - I just bought 2 EV elx112ps which sound really great. Warm, punchy, loud and detailed. I know we could get more out of them with some subs and I really only want one sub to carry, plus I'm on a budget. Considering that having one sub to each top would probably be balanced as designed, I was considering going with a JBL PRX718s, which has more power and goes deeper, thinking I could get away with one sub and have a nice balanced system. Is this a good idea??? I can get a PRX718s for a very good price it seems. Thanks for the help oh wise ones!
