Ok. I accept that. I don't know I would put multiple unused drivers in a room. A friend of mine has a very well tuned room. But he was sort of stuck. He drug some unused speakers out of his room and once they were gone said the whole system clicked much better.I can tell you this much, all those room treatments and active bass traps are a lot more responsible for the sound than those two woofer columns.
I think I am saying, leave as many speakers in your room as you want if your goal is cycling gear and listening to all sorts of different equipment. If however your goal is to fine tune a system and make it as good as can be, get rid of unnecessary speakers that are doing something.
Ron appears to me to be stuck in no mans land. Unfortunate. Too bad there isn't a easier way to move things around.
