Can you explain the reverse polarity for the BK in more detail? Both my BKC units are upside down, this won't affect them being wired in the "correct" way, will it? What about TST units? I think mine are all the same way, too.
There is no right or wrong way to wire them as long as they end up in phase with each other.
My understanding is that the TST's normal orientation is hanging down. The BK's normal orientation is upright. They are on the same plate now and I don't want them to cancel each other out. Since my TST is hanging in default orientation and my BK is now also hanging not default orientation, one pair of wires needs to be reversed for these transducers to be in phase.
Normally the BK is the easier one to change because of the hand tighten speaker wire terminals. Since I faced my BK-CT's terminal to the front of the plate and the TST's built in wire is currently just twist connected with electricians tape in an easy to reach place, that is where I rotated red and black.
PS, I could definitely see rotating that BK to make reaching the terminals easier, but my thought was that the speaker wire path facing front was better.
I should flip the polarity back just to see how much of a difference it makes. If they are running opposite each other different things could happen.
1. Signals cancel out lowering overall feel of effects.
2. The front of the plate and rear of the plate could wobble, ie. front goes up while back goes down.
3. The signals are at different enough frequencies between the TST and BK that there is no discernable difference.
So it could be much ado about nothing.
