Setting up stereo Rel subwoofers….

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.

Hello @doni ,

My REL Carbon Limiteds came with the REL Longbow Wireless Receivers built in.  Here is from REL's product description page:

Finally, you can connect to the Carbon wirelessly, using REL’s Longbow transmitter, featuring the same functionality and inputs as the ones on the rear panel of the Carbon. This eliminates the long cables from amplifier to subwoofer and has a range of about 45 feet. You can read the full definition of the Longbow system here, but suffice to say it’s the easiest bit of hardware we’ve ever used. Two switches, and you’re done.

As we’ve mentioned in other REL articles, switching back and forth between the Longbow and wired connections reveals no difference in the character of our reference system’s LF performance. The receiver is built into the Carbon, but you will need a transmitter, which has a cost of $300. The Longbow can control up to four separate REL’s in mono mode, but if you want to run a pair in discrete stereo mode, you will need two Longbow transmitters.

The Longbows work great, and placement becomes imaginative instead  of limited.  I tried so hard and long to put my subs just inboard of my main speakers, and went through two brands of subs because of the boom.  Now they are way outside of my main speakers, actually along the sidewalls.  Take a peek at my system photo...those are my amps inboard of my speakers and the subs are out of view.

BTW, you can add REL wireless to most of their subs, they have a few systems, model dependent.
