So why after I run Dirac on my XMC-2 does my bass seem to be lacking. I have one sub hooked up to the middle sub and one hooked up to the left. Problem is when Dirac runs it wants to run the right sub but their is no sub there so I get a signal to noise error. So I have to only say I have a middle sub. But I have to set that sub to mono as it won't let me set it to LFE with only one sub connected then after all is done I turn my left sub back on, and then set the middle sub back to LFE. But my bass seems so not there. Not deep at all. Any ideas? I do not have a minidsp.

What some folks are doing is using a Y cable connection to the Left and Right sub outputs to connect one sub, then use the Center sub output for the LFE. Support is working on the fix for the Left/Right Subs set to Mono and Dirac "sees" a Right Sub that isn't there. I don't have a clue as to how long that will take to get fixed. It's gonna help quite a few folks who want to use LFE and only have two subs. One work-around could be to use any old amp and any old speaker to connect to the Right Sub output just for Dirac runs. |

Also, when you add the second sub in post calibration, the XMC-2 cuts voltage to the sub outputs thereby reducing the level by ~6dB. So, to get back to the right sub level ,you need to increase the subwoofer trim by 6dB. Once they correct the issue ttocs is referring to, this won't be necessary, ad the XMC-2 will properly level your subs. |

I just ran Dirac on my XMC-2 with both subs on the center channel and now my bass is super weak.

Has this been corrected in the latest firmware? I have dual subs but I don’t set them to LFE only. Will this be an issue for me when my xmc-2 arrives? I now have them set as stereo and I am in no way lacking for low end.

Hi - Just wondered if anyone know if the left/right sub issue has been resolved yet when connecting to Dirac? Thanks Jim |

I just ran Dirac 3 last night. Dual subs up front set to dual mono left and right. Bass is super weak and sounds nothing like it did with my Xmc-1. What the heck is going on and how do I correct for it? Just raising the subs level doesn’t seem to do the right thing. Very very frustrating!

I'm using the Harmon +6dB and its much better. |

Ok I remeasured last night adjusting the levels according to the guide I found and loaded the Harmon +6db target curve. It sounds fantastic now. Much closer to before, but I think better overall. It is brighter in the upper end as that harmon curve is flat and not rolled off at all. My question now is if I follow the recommended 1db per octave rolloff that puts it down -8db at 15360hz. That seems like a steep rolloff in the highend. Am I missing something? Why would you want to cut the high end off that much? Also, holy moly the test sweeps are loud compared to the other version. Is that normal?
Oh and a shout out to Keith. I spoke with him on the phone yesterday and he was super nice and helpful. Thanks again!

Thanks again!I think the volume in 3.0.9 is even lower than earlier 3.0.x versions. Do not set the volume too high on the volume setup screen. Dirac raises the volume while calibrating. I think someone measured the raise to about 16db in earlier versions. Don’t think 3.0.9 raises as much. I have added a slight roll-off on my Harman +4db curve, -2.5db from 8khz to 20khz. Harman +6db is too much bass for my taste. I have also custom curve I did myself. It goes flat between 150hz and 10khz. with a slight +2.5db raise in the lower end and a -4db to 24khz following my speakers measurement closer. |
