I’m swapping my EP600 out for two EP500’s. This is my first time using multiple subs. My receiver does not have two LFE channels. I use Audyssey, and I like it. So I was just pondering what would be the best way to hook these up. I can either daisy chain them or run two cables back to the receiver. They need to be placed on the front (screen) wall, facing into the room. They’ll be equidistant from the main listening position.
You guys who have multiple EPs have any tips to share?

Michael, yes this can be done, and I also love Audyssey. I've done it with a 600 and 500, and then a 600 and two 350's spread around the room. Before you proceed, the main thing is to calibrate each sub individually. I had them all daisy chained, but that is the same thing as splitting at the receiver, same outcome.
Calibrate Sub 1 first with Sub 2 turned off, so Sub 1 matches the spl of the other speakers, say 75dB or so. Then turn off Sub 1 and rerun the pink noise and match Sub 2 with the speakers. Then turn them both on....
Now, Jakeman helped me and said to calibrate the subs say 3dB lower than the speakers, so the combined slp comes up to where the speakers are. I experimented and think I just calibrated everything to the same SPL. Audyssey will do the rest....
After you run Audyssey the first time around from position 1, you can calculate, and check what it did to the sub levels. If to low or to high, you may have to adjust the receiver level and/or the subs volume knob, then rerun.
Then you can rerun Audyssey from all positions, and enjoy.

Thanks Randy. I wasn't sure if there was a driver for daisy chaining the EP's because of the DSP technology or not. I'll have independent cables run through conduit back to the receiver in the event I buy an AVR or Pre that has provisions for two subs.

If you all ready have the cables ran for two sub I would just split the Sub out with a rca splitter.

I used a 'Y' (Wye ) from the connector at the wall plate to the AVR in the equipment closet ... all of the six runs to the sub outlets are in-wall. If I'd thought about it at the time and had the chance to do it over again I would have ran a single run to all six wall outlets and T'd off of the main run for each outlet ... would have saved from having six different inputs on the wall outlet in the equipment closet and having to need just that much more cabling.

I'd run two cables and run them off a BFD so that you can equalize them independently using REW. Nah, I probably wouldn't. I'm just messing with you.

I hope you're kiddin Tom... I don't want to open that can of worms. Yuk, frustration and self inflicted insanity would be the result.
Thanks guys, a Y at the audio processor it is.

Mike, that probably would be the more convenient connection, and convenience is really the only factor to consider, since there should be no audible difference. If the two subs were very close to one another, a short daisy chain connection between them might be the way to go.

Yeah, I think you'll have to use a Y, since the new EP amps only daisy chain on XLR connectors. Don't know that it would work with an unbalanced connector to the receiver.
