Newbie with a couple of other posts. Looking for advise on a couple of fronts which I will explain below. Didn't have much information in first two posts so here we go.
See attached for room information. The room consist of concrete floor with carpet, one wall is concrete and entire room is studded with insulation. Ceiling is a drop ceiling with standard tiles. The room is fairly naked with the exception of one small record bookcase and bass traps. Doors have an acoustic mat but admittedly thin. I did this to the doors and added DIY bass traps blindly. The traps are6 inches deep with acoustic insulation inside. Speakers are currently set dimensionally for decent imaging.
Sound system is 2 channel speakers which are the 2 way ported Zaph ZRT's that I built. Note that I went with recommended build port length for 30 hz and have not tried tuning (due to lack of knowledge) nor anything related to resister changes for tweeter. Running a Schiit Freya and Mono Schiit Vidar's. Primary listening is Vinyl.
Measuring done using minidsp UMIK=1, laptop and mic to rca adapter plug using laptop soundcard.
I have included image of some test results last night. I did remove some of the measurement graphs to clean up the graph which is set at 1/3 smoothing. Other measurements not viewed on this image were pretty consistent with what you see. Now I am not sure I have things set up correctly although was disappointed with the results of the included measurement in which I removed the traps.
A couple of items I question is my setup based on graph results compared to what I have been studying online. On my graph I don't notice the steep climb from 10 hz until response is captured.as viewed many times on tutorials. Is my measurement results abnormal? I also question this as looking at the waterfall my results look very different. Many very thin lines next to each other.
If I understand correctly I have a mode between 50 and 60 hertz, another around 175 hz and yet another around around 600. Very open to any input on what I might try from any front.
