I have kind of thought about something along those lines. For now I am mostly considering a design that will easily allow that as an option later on. If anything I am going to experiment w/ a single Fountek JP 3.0 per side. It will not give me true array performance but it will give a good idea of the high frequencies that I might be missing compared to no tweeter(s) at all. I think it will be a very effective demo but only at a given height and distance.I could easliy add a tweeter "panel" later on. Lots of things to consider...
Ideally I would like to have these in my bedroom and build something very nice for the living room. I am trying to not get too carried away.
Thanks,
Aaron
