Beginner trying to figure stuff out.

So you think the LF bump is from the sub? can the sub be measured separately? If you have a 2.1 system it should be measured as 2.1. That way AL could also time align your sub, which can boost sound quality significantly. A decent tripod is a must.

Here is a measurement with the sub off .You can see the difference right? I currently have version 2.0, for a 2.1 measurement can I use version 2.0? Will look on the tripod. I used a cushion on the sofa in the past . My DAC is only supporting 2 channels, for 2.1 I will need a DAC that supports 3 channels?

Hi, This measurement makes much more sense. The difference here is the room. I am not sure about your question with the AL version. At any rate if it doesn't then upgrade. That is if you can measure the sub as a separate channel. It isn't clear to me how the sub is crossed and from where. DAC/Amp?

The subwoofer is connected to the AMP this way,

Using my current filter, the sound is much better, tighter bass, less "boomy"

What frequency have you set the LPF on the sub to prior to measurements? A plot of the sub alone would be helpful. In addition, you may want to consider moving the sub around to get a better L/R channel balance.

Haven’t touched the sub on measurements, it’s connected to the amp, so I think can’t create any filter for it. So it’s like a right channel whole speaker. Sadly my space so limited, that’s the space available. Can’t move other place. Thanks for your input!

OK. I am aware of this notion of connecting the sub to the speaker outs of the amp to retain the sound signature of the amp. Yet this really relinquishes some of the best features of AL. To achieve the best that AL can give you it would be preferable to measure the sub as a separate channel. What you get now is uneven speakers. Obviously it sounds better then with no AL but you are far from the full potential.

Hi, Newbie here that also got lots of help from a friend, but still on learning path. Using version 2.0 Wanted to ask if the outcome of my measure are acceptable or what can I do to improve. I just read that increasing the memory to 160% and reducing time to 7 sec from 10 sec. Please see belowView attachment 81726

The measurement looks fine from here.

I recommend that you experiment with different target shapes in the bottom. What you have here may be perfect for you, but perhaps you should try something that doesn’t have the sharp bass peak as you are getting now. A bass that doesn’t rise, but starts to round off sooner sometimes sounds faster and deeper … and sometimes the whole speaker sounds faster and deeper. This is a matter of preference, and now you have the tools to find out yours…

Many thanks for your help! HQplayer has a new feature to stream same music into 2 DAC’s. I have an extra DAC that I can spare to test, but don’t know if I can send the convolution filter of the sub as a 3rd channel into this DAC only. Will check! Although will be maybe 192hz / DSD128 instead of DSD512, for low frequency should be fine. Might need to ask for a 2.1 AL upgrade

Many thanks! This means have a flatter and wider mountain instead right? Then the rest of the curve follows as previous correction curve?

Yes.
