Dirac Live / room correction target curves

[Heimkinoberatung]

Hi guys,

I am a Home Theater enthusiast from Germany and following Audioholics since years.
Just about to finish my HC build process (ok, you are never done...).

Use Dirac Live via HTPC Solution and have one major question nobody (even Dirac support) was really able to answer, maybe I have some luck here in this community.

My question adresses the set Target Curve for the Base in a SMALL speaker configuration (bass management via AVR) and the separate LFE channel.

Both are getting played via the same subwoofer (SBA Array) of course.

So my concrete question is IF it´s an issue to set DIFFERENT target curves for the bass part and the LFE channel?
As both signals getting reproduced via the same subwoofer, but with different EQs

Or is it highly recommended to shape / use the identical Target curve? Have you made any experience here?

Generally not only a question for DIRAC users, but any room correction system which allows manual seperate Target Curve manipulation for each independent channel for a multi channel system.

By the way, is there already a discussion / thread opened here talking about Target curves and how to get to a good one in this forum? If not might be really worth it

So far, thanx alot already in advance

Hi,

nobody any experience on that matter?

Nope but tuning in to see....I'd think multich Dirac experience remains with a relative few due how new it is, there's more 2ch experience out there. Onkyo releasing avrs with it should help expand the numbers of users, tho.

This is a topic not only for Dirac, but ANY Room EQ System where you can individually tune your target curve, e.g. with Audissey app or anthem room correction

Is Gene reading here? If so, maybe a comment from your end how you did that on the storm audio would be great.

Did you ask the manufacturer about this? I have only played with Dirac Live's 2 channel trial version but have used Audyssey for many years and I know for multiple subwoofers you would just time align them and then EQ them as one. In your case, I would think it depends on the FR range of that same subwoofer and the specific design. For example, if that subwoofer has just one input connected to the same output on your HTPC then obviously you can only have one target curve so I guess that's not the case here. In you are using two different outputs each have its own discrete channel and there are two inputs on the subwoofer for that purpose, then you would use two target curves. Does that make any sense?

I don't think there are too many members here who have experience with your kind of set up, but I am not really sure so let's wait and see if any experience users would chime in.

In any case, if you are going to experiment on this, I would highly suggest you use REW to plot graphs of each, in order to see which way would give you the best results.

Hi,

my setup is completely normal and standart. Speakers set to small and using SW for Base.
Same SW plays LFE channel.

As said with Audissey app ,anthem room correction , Dirac, Trinnov... you can change the target curve for EACH individual channel. And the LFE IS an individual channel.

So I am surprised nobody has adressed this topic so far, I guess at lease Audissey might be widely used here..

So maybe I brought up something also for you to think about as a potential point to improve your sound performance

I think in that case I have already answered your question. That is, if the subwoofer has only one input and ia the same one that plays the same frequency range, then you will only have one target curve. Yes the sub will play what you call the "bass" that is redirected from the other channels based on the crossover settings, as well as the bass from the discrete LFE channel encoded in movies or multichannel music that has the .1 (example:5.1, 7.1 etc.) channel but to the AV processor and REQ (Dirac, Audyssey etc.) the subwoofer itself is just one channel, now that you confirmed it is a normal/atandard setup.

Sorry to say that´s unfortunately wrong. I use DIRAC Live and the filter on my PC directly and send the decoded signal via HDMI into my AVR which is at the end only doing Volume control.

But also in case Dirac /Audyssey, whatever is running on the AVR the Mains / all speakers and the LFE are still different independent channels where you can do DIFFERENT and independant settings for your target curve.
So "the Subwoofer" is not just one channel, but gets signals from 5, 7, 11, 16, whatever different channels from all your speakers set to small and the LFE.
