Dirac live is off but setting chnages not making a difference. Room sounds right heavy.

[Ssmokeyy]

I have built a custom room for my theater. 13ft wide 15ft long 6.8ft ceiling after sound proofing.. Small room to start with just got smaller once i sound proofed it. Avr is a integra drx 8.4 with a custom anthem mca50 running the front 3 speakers. Full klipsch setup. Rp-8000f gen 1 towers with a rp-504c gen 1 center. 7.2.4 build. Two stereo integrity 15's in the rear off a crown xls 2002, psa audio dual 15 up front. The sound is right heavy. I have run dirac 3 times with wide focus option for more seats. After calibration seems like lack of bass and lack of mid range from the front. I go in to level control in the avr after and check the level output with rew and the umik-1 to find spl differences between speakers at my listening position to be off by like 8db from some speakers. I have tried setting the all to 80 dB with subs at 83 dB sounds right heavy still and boring. I have tried setting everything at 84 dB and still the same. I tried using the harmon curve +6 dB file and yes some more bass but still I have the other problems and I don't like how the bass comes on. Seems like no bass after 50hz. Under 50hz crazy amount of bass. Good for movies bad for music. Music always sounds off like missing aound and right heavy. Is there a way to override dirac time delays but still use dirac? Or correct this dirac problem?

I was told by dirac to set the sub volume using the sub gain a little higher than the speakers and proceed with calibration.
You can change the target curve also but yes dirac nuttered my bass. I did a 10db harman curb and it is better but still lacks.

Rooms and walls make strong standing waves depending on speaker/listener locations. Subs and woofers need the room corners and mics ought to be more like your cardioid stereo ears. You may have to average many listener/speaker combinations to suit several listeners as radial speakers are not linear plane waves and more like point sources.

You should calibrate the system to whatever volume your going to actually listen to it at. 75dB-83dB is fairly standard, but some might like it louder, especially if it's Home Theater and not music. Perceived volume will be different if it's configured @ 75dB opposed to 83dB.

If you are seating by the back wall, your probably going to have a really, really thick sub 80hz bass. Try moving around the room and see where it sounds "good". Take a measurement in that spot. Compare to the measurement at the current listening position. That should give you a good indication to what tonality your looking for.

As for curves, they are user dependant, but for me and my system, a small 3dB rise starting at 150hz and tapering off @ about 50hz is all I need. Keep in mind, the rise on the slope is only about .3 dB @ 150hz.

Dirac live kills my bass output, so I just switched to running a curve using REW and have much better results

Have you tried Dirac support? They may be able to offer better help.

Are you using the AVR's included mic with the Integra app? It seems to suggest that only offers more basic correction and that getting a UMIK-1 and using the PC application might give better results.

Also if you were able to take some measurements it would a lot easier to know what's going on, which is something else the UMIK-1 would enable in combination with free REW software.

don't use dirac live its useless in my cinema professional system b-chain , if they made it so it can be outboard box with , 32 channel xlr rca db25 with 20,2000 filters for each of the 32 channels and £200 retail i might be interested
