Setting up stereo Rel subwoofers….

In home theater setups, I placed the subs near the corners for maximum gain/bass. For audio, I placed the subs out into the room, once behind the speakers, the other times on the outside of the main speakers. I never wanted to actually hear big bass, just a better over all fullness with clean bass

Hi @jastralfu 

If he sets it up the way REL states like I posted above, the subs won’t need to be moved, the only thing he may have to do is adjust the subs volume down slightly.

REL will have you moving the sub around during set up if you only have a single unit, to take advantage of boundary reinforcement because of the lesser output.

I did not find this to be true in my basement.  With two Rel Carbon Specials just inside my main floor standing speakers, I got significant boom from right behind me (I have a wall around my utility closet right behind my couch).   For me, moving the subs well outside my speakers into the corners of the room, asymmetrically pointed, the room nodes smoothed out a lot and the booming decreased.  I also added bass corner traps in various corners of the room which also helps.  Now people can not even locate my subs, but they add significantly to air pressure and soundstage of my floor standers, running full range.  To allow me to have flexibility on placement, I run my subs with REL's wireless system which is fast and seamless.  Of course I still go through the adjustments of phase, frequency adjustment and volume.  It is set and forget.  For demonstration it is easy to click the wireless senders on and off.

If the position of the duel subs will allow, don't overlook option to make high-level connections directly to respective speaker binding posts vs amp.  REL has a YouTube video on same.

@fastfreight , using two subs, how do you connect them to the wireless sending/receiving units?  Thanks.

Here’s how it went, to this point. I just twisted both red/yellow wires together, hooked them both up, and left one off to do the process.The crawl seemed to work in that there did seem to be a couple spots where the bass seemed full, louder. That provide a lot of bass for sure. (I may go back to it, try it again). Then I set them up just outside the main speakers (Mofi 8’s which go down to about 47hz afaik).

I wanted to try the way REL suggests and see if it integrates well that way. Yes, it does sound great- I only use the system for music. I have the crossover at 13 clicks, the vol at 15 and only using one wire. I tried to get good bass but not too much, kind of integrated smoothly. One thing was: I could not tell which PHASE was better, they both just about sounded the same. Not sure how big a deal that is... I may try 2 wires again but I want to be able adjust the volume a few clicks.

And I don’t know if 13 crossover clicks is perfect for the MOFI’s or how far that is- all that I saw suggested was the lower is better.

I do think this has turned these excellent speakers into the best system I’ve ever had, easily. I run an Eversolo A8 and a Musical Fidelity M6si.
