O.K. I am finally going to just try and stack them in the front and see how it goes. Ran the SMS-1 just to see where I stood so far and was pretty surprised. I guess I wont be making too many adjustments.:p

    I'm not sure yet. I'm just gonna listen to them a bit more. I think the SPL is higher but it's different. I was just getting tired of them popping so I wired them.

    Likely because they are driving the room from a single location so will excite different room modes than when they where in separate locations.
    Are they stacked in a corner?

    No. There are no corners where they are now. They are essentially in the middle of the room. The popping was from the wireless interference. I just got tired of it.

    Yes. It was intermittent but enough to bother me. I actually had it under control lately with no problems but then suddenly, it was unmanageable. I must have changed something somewhere.

    Is this a common problem with other users owning this model of subs. Does it happen more often with the subs spread wider apart.
