We just have 2 201's. We set up the cheaper, uglier, but more PA-looking speakers for the mains. We don't have any subs. Music style is CCM rock (Hillsong, Chris Tomlin, etc) and black gospel. If I set up the KP's, they'd be mains. Room is fairly small, 25x40, but I think this congregation will want it pretty loud. I'd like to get a sub, especially for the type of music we're doing, we just don't have one (or any money for one) at the moment.
I'm in northeast Florida. I'm not sure what price I should charge for the speakers. I'm not familiar with what they go for or what kind of condition the important stuff is in. Haven't gotten a chance to test them.
