REL owners, how many clicks on your gain and crossover

I have a 7i and have wondered if I added one if it made sense to connect the red for one of them and the yellow for the other? Anyway, I think it is good advice to follow REL until you need to do something different. 
 

As for placement, I have a small room, and I found it best to pull the sub out even with the face of my speakers which are out from the wall. Otherwise, I would get a bit of boom. 

as others have said, follow the instructions step by step, to the letter (and use the speaker level input/speakon if at all possible)

asking others for settings here is foolishness -- this is completely room and system dependent

I don’t think it’s foolish. Rel videos say 15 clicks -3/+3. That’s way to much for my room. I’m now using both red and yellow wires into amp. I’m running 4 clicks on gain right now as I explore what’s going on. I said I know all rooms are different and just curious. Your statement “foolishness” is why I stay away from these forums most of the time being a member here for over 15 years.

In the manual they start with the crossover and gain at their lowest settings.

I have mine placed next to and slightly behind the front of the speaker. Dial in each sub by themselves as in the manual( I just disconnect the speakon terminal from one sub).

Here's the Tx series manual...

REL recommends starting at 10:00 position and tuning from there...I generally change one click at a time...
