Hi guys, I am getting ready to run Dirac Live in the next day or two. My question is, I have an SVS AS-EQ1 sub eq and was wondering if I should leave it in the setup when I run Dirac in my new setup. I used it with my Pioneer Elite SC-25. My new setup is a 5.1 system with the XMC-1 replacing the Pioneer. My new setup is this: XMC-1 XPR-5 SVS AS-EQ1 Kef Reference 3's for mains Kef 200c center channel Def Tech BPX's for surrounds Seaton SubMersive master slave sub setup My room is 14x24 with 7 1/2 foot ceilings and the system is along the 14 foot wall. What should I do? thanks guys for any suggestions. Mario Mario, see the above post. I jumped the gun on my response. I am not that familiar with the controls on the master slave option for the Seaton's. Do you have the ability to phase align without the eq1? How do you have the eq1 set up now? Is there a seperate input for each sub on the master? Tony The Seaton Master/Slave pair have one 4,000 watt amp in the master driving both subs in parallel. The slave has only an amp input and no controls. I have a pair on order. If I'm lucky and find a location that produces a near falt response, I intend to stack them. |

Is there a seperate input for each sub on the master? Tony I also have the Seaton master and slave set up. Only control on the amp is volume essentially. There is a button for DSP settings, in or out and it uses a preprogrammed DSP set, so a choice of 2 DSP settings, not user modifiable. There are no phase or frequency controls, volume is it., no auto on/off either. You connect the slave via a 4 core cable from the sub that has the amplifier on it. The slave just has a face plate where normally the amplifier is mounted and you plug the other end of the 4 core cable into that. I have the 240 volt version and the amp runs at 6000 watts in 2ohm with the slave connected, 3200 watt into 4ohm as a stand alone amp I think it was. Don't have Dirac yet, the microphone is sitting with UPS in Melbourne, but hasn't gone out for delivery yet. No great matter as I haven't received the key for the software yet anyway  Cheers Z |

Given all this, my original statement stands. There is no need for 2 eq setups if the slave option has no way to set the delays on the slave and it's relying on placement alone.

Thanks for the replys guys, much appreciated. The master/ slave setup is awesome in my room and can not wait to try Dirac and get it all dialed in. I will remove the AS-EQ1 from the setup and try it out. Thanks guys, will keep you posted.

I read the update, but the only thing I don't understand is why can't the individual sub delays in the XMC-1's independent sub controls be utilized and then a summed response be checked by dirac? Also the delay's for the channels cannot be changed in XMC-1's version. In the Dirac Live PC version it can be. I sure hope the full version for the XMC-1 take us past where we are at now with the XMC-1. Just having the option for dual subs and then to EQ separately and hope the summed response comes out ok is crazy. I mean this is sub eq 101 type stuff.
Now the improvement in the impulse response is awesome and makes a huge difference in sound in my opinion. If we could get the bass management right we would really have something. I might have to get the Mini 10x10 ($499) for enough delay control if this isn't fixed in the full version.
btw the way I tried the dual mono then mini dsp correction afterwards but still did not work as well as Mini correction first then run mono for Dirac.

I agree, this can be fixed either by emotiva or dirac. But at the same time, I also think that if your going to have more then one sub in a room, that a external DSP should be part of that upgrade. The question becomes, which is better for most users. Most users out there will just get a second sub and place it in a symmetrical location to their first and try to get the levels the same. no phase/time alignment no nothing. In that situation, does dirac make an improvement? It is something that I have not tested. Tony |

The more I read the more convinced I am that my decision over 25 years ago to go with one big, high quality sub with an equal quality amp was the right one.
Happy New Year

OK! Let's summarise it! It is not recommended to use stereo subs for the dirac processing but two subs on the mono output via splitter. And after dirac did it's job put them back to stereo again? There is one small detail before running dirac - you have to set all your speakers in the dirac preset including subs. You do all the fronts, centre and rears but how do you set the subs - mono, dual mono or stereo having in mind that you use only one (presumably the left subs output)?

You do all the fronts, centre and rears but how do you set the subs - mono, dual mono or stereo having in mind that you use only one (presumably the left subs output)? Subs remain set to mono. Quick and dirty summary - Configure as mono using a splitter off the left input going to all subwoofers - Phase align subwoofers to the main listening position via phase knob or via physical placement - Run Dirac to correct for the sum. Grab Beer. Job well done. Tony |

I would only use stereo subs if I intend to cross my mains really high, say above 150Hz. Otherwise, I'll do mono subs, phase-align them as best as I can to get a flat response or at least no dips, apply Dirac on the combined channel, then leave them be. |

I still plan to try to at least get dual mono working with Dirac. I plan to let dirac do its thing then apply correction through the minidsp to align. But that is pretty low on my test list. Tony |

I only have a switch for 0 and 180. By phase-align you mean both to be either 0 or 180? So far my set up is 2.2 channel (stereo subs) and I only use it for music, no movies and no surround. How can I take advantage on the stereo subs if I only use one output. There is another option - Rel Acoustic Subs could be connected directly to the amp main outputs. I could do that and run dirac on two channels only.
Anyway I will run many different tests and let you know about the results. Thank you for helping me.

In a 2.2 setup stereo subs could work with Dirac. I don't see any reason that it would be a problem. Since you only have the 0 and 180, just leave that alone. Your only real method of $free$ phase alignment is based on physical location (most newer subs have a variable phase knob). Give it shot. The only issue that I would be looking for is at the crossover point. You will probably have to play with it a bit to get a nice smooth response. Try going lower and higher then the MFG recommended crossover. Tony |

My fronts are set to large. They could handle 30 Hz as well as the subs. The room is square 13X13, acoustically treated. I don't thing I will have problem with the crossovers. As I said I will run a lot of tests tomorrow and share my experience.

Actually I've come up with an idea. First I will run Dirac trial on my iMac and see which way sounds best. Then will take my chances and install VMware with Windows 7 on my macbook and run Dirac LE with the settings that I liked with Dirac trial.
