Missing Bass

[specht007]

Hi all, I am missing bass with the latest measurement I took. I am using AL since a couple of years and haven't really changed anything in my setup. Setup is 2 Subs + 2 Mains, DAC is a RME ADI 2 Pro. I am using an IMG Mic Preamp and a IMG EC-40 calibrated Mic.
Any ideas greatly appreciated!
Thanks...

It appears you are trying to run 4 channels of correction with only 2 source channels available with an RME ADI 2 Pro DAC. This will not work with digital XO setup. If your subwoofers use plate amps which typically have LP filter capability, dial in the desired 78Hz filter there and set AL up for two main channels. Also, when preparing plots for comment or evaluation, consider setting the range on the Y-axis to about 50 or 60 dB so we can see what is going on.

The one thing that stands out here @specht007 is that your target is literally horizontal. To my years that type of target is very bass-thin unless I play extremely loud. Try to tilt the target, experiment with it. I typically find my sweet spot on a downslope around 2-6 dB, but there are many users who swear to much more than this.

As @juicehifi suggests, you might try a target that looks more like this...
