Budget?What center channel speaker would you recommend to use with the JBL Stage A130 ? I have a 2.1 system, and I'm thinking of trying a center channel speaker.
If you're not looking to spend a bunch of cash to experiment, I'd have a look at the Infinity Reference RC263. Aside from that, the Emotiva C1+. The C1+ can be had for $249 shipped, the RC263 can be had for around the $300 price point.
Alternatively, you can get a second pair of the A130s and use one of them as your centre channel.
