Sub woofers these days don’t use a 12v trigger to control them turning on or off, they most all have an auto turn on, which is simply based on when signal is fed to them from the receiver via rca cable. XLR is also not needed for most of subs today (with the exception of residential DIY setups), and rca is used in almost all residential subs. This will be the case for all of the subs I have owned as well as any jl audio and svs sub. For the run to the projector, I would also throw a USB in there as well. I made the mistake and had to do this later, so I could connect things like wireless keyboard dongle to end of that cable, to control computer. Since computer keyboard is Bluetooth and not wifi based it needs to be line of sight. Also was helpful when setting up MIC and using REW. Based on the number of walls you have between listening area and rack, I would say remote connectivity could be spotty with what I have experienced using my harmony pro elite. Might be worthwhile to swing into best buy, and atleast test it out (even if you return it and go another route) and you can always take it back once confirmed. What else am I missing guys?
