Now, I am very happy down to 20hz. Do not get me wrong, it was sounding fine and was blending well. Now, I have spacious sound at the bass frequincies too and the sounds start and stop and die in the room more naturally. Overall it sounds like the system had just thrown another veil over its sound that was covering some of the bass. The denser passages sound even better now. 

Kodomo, here is some sanity check for you. I do not object what you do, I just paint for you the pass I went and the way how I asked myself some questions. You feel comfortable with your bass session. This is perfectly valid state of mind. Do an experiment.


Fist switch your playback to mono, I mean use only ONE channel, let say left and play only mono recordings. The reality is that you can play even stereo recording’s one channel, but it would requires a degree of experience that you might not developed yet. Remember, this is not about music listening but about a very targeted audio listening. So, you flip you system to a mono mode with whatever means it comfortable to you using let say juts left channel of you playback. Now take a right channel bass amplifier and right channel bass speaker section and place them atop pf your left channel bass module. Make sure that the bass speakers are in-phase. Drop between 3 and 8 dB on each bass channel or even better use RTA to flatten bass response, while making sure that bottom and top bass modules (former left and right) run the same amplification gain. Now listen the result. You might feel a lot of improvement, including your HF response.try


What I am saying is that looking at your installation I see a conspicuously empty space above your current bass modules (those acoustic treatments are not relevant). If your woman do not insist to fill this space with a ficus and you have some money and time to burn then you might consider adding another 2 drivers per channel, doubling your current bass modules.  Besides all things that you might expect from the experiment above there is a thing that you might know until you try. The thing is that for whatever reasons the little line-array that your bass speaker will form do work spectacularly well with Macondo-like configuration. There are of cause many textbook advantages of LF line-array but based upon my experience those advantages are particularly sweet while line-array used with speakers of your type.
