I'm considering the option of reconfiguring how my subs (SVS SB-13 Ultra x 2) interact with my XMC-1 system. I've currently got them plugged into the Sub L/R XLR channels on the XMC and set to play in stereo mode rather than dual mono. The SB-13's are capable of accepting a full-range signal from the pre/pro and passing high frequencies off to the main L/R's, so I am interested in trying that configuration so that I can enjoy the subs when playing music in reference stereo mode. As far as placement is concerned, I have both subs placed symmetrically at the front stage, inside and just behind the L/R towers and equidistant from each other. That is to say, the arrangement from left to right on the 12' front wall is [Main left / Left sub / Cabinet / Right sub / Main right].
Does anyone have opinions or experience on this kind of external bass management? I understand that Dirac will have to be re-run and that it will treat the left-side floorstander and sub as a single channel, and likewise for the right side. I also believe the LFE channel for surround modes would actually not be active in this configuration... would it be advisable to get a 3rd (and 4th?) smaller sub specifically for LFE that could be placed on toward the rear of the theater room?

For speaker level sub connections, set front speakers to large and sub(s) to none in the processor. The unit will send lows to front main speakers. Use sub controls for level match (loudness, crossover, phase, etc), rerun Dirac if using. Get it right in stereo first.

Reference stereo bypasses all digital eq including dirac Yes, but I don't intend to listen to everything in reference stereo. Movies, TV, games, and the like will all continue to be played in surround modes in which Dirac is engaged. But I'm not about to pull back equipment and reconfigure cable connections every time I want to switch between music and non-music activities, so I'd like to make sure that this new configuration will not have adverse effects upon the functions that comprise about 80-90% of my theater-room usage. |

Also, there is a way you can use reference stereo AND have subs play. I do it and I use my sub's controls to set up my sub. This is made possible because my Rythmik sub has the ability to take XLR inputs and RCA inputs have the XLR rely on the pre/pro's controls while having the RCA rely on the sub's controls. Some other subs have that option also. With my system, I find that having a sub with the XMC in reference stereo sounds better than using the XMC-1 w/DIRAC or having the XMC-1 in reference stereo w/o a sub. It's a fairly complicated looking approach, but it truly gives me the best of both worlds...I get multichannel and DIRAC for that or get pure music with full range when I want that. If I needed more taming of the sub, I suppose it would be possible to work in something between the XMC-1 and the sub to enable that (of course, it would have to go back into digital for digital correction then back to analog).

I'm about to set up my system the way you are talking about. Set your main speakers to full. Your sub to LFE. Then wire them the way you were talking about.
You may have to adjust your sub placement as well as your settings, but I think that your going to like the result.

Taking klinemj and repeetavx's responses together, it sounds like I need to have my main outputs from XMC to each subs by XLR (and then onward to the mains' amp stage from there through the subs' bass management), and then also the sub outputs from XMC to each sub by RCA for the LFE channel? Do I have that correct? Will the subs work properly having both XLR and RCA signals coming in at the same time?

Oh, you want LFE and Bass Management. The proper way to do that is with the Preamp/Processor. You would just hook up the Stereo Bass/LFE outputs to your subs and let your XMC handle the bass crossovers. The XMC does have stereo bass management!

But I want to configure it so that I can use my subs while playing music in reference stereo (which is the only way I can use an external DAC with the XMC). See the original post  But I ALSO want to have LFE for non-music situations where I will be using Dirac and relying on the XMC's internal DAC. And I'd like to set everything up so that I can switch from either situation with push-button ease -- no swapping around cables. |

No need to make things complicated. Just use a miniDSP 2x4 balanced and you can have the best of all worlds. Run the sub signal as mono and I think you'll be happy with the results. Alternatively you can keep the subs in stereo and cross it over for each main as you see fit. Will cost you about $180. As for adding additional subs for the HT, great next step. Just keep in mind that with the SB13s, you'll need comparable subs in the back to equalize the bass response. You could even tune one of the four subs to act as a mid bass module.
