Since I am totally blind, I use screen reader software to read me the screen. Jaws for Windows, Voice Over for iPhone, and Talk Back for Android. The developers do not always make their apps work with screen readers, that is what I mean by accessible. Sometimes they cannot make them accessible, sometimes they are not aware of screen reader and people with disability accessibility, sometimes there will be fights because developers of the aps say that it is the developer of the screen readers responsibility and vice versa. Companies have been sued. What is not accessible is the actual curve, graph, and the ability to make the dots. I can run the calibration, but after I get the result all I cand do is change the size of speakers, distance, volume of each speaker, pick target curve roll off 1, turn off mid-range compensation, turn off dynamic eq and the other settings there. I can not do the filters, curves etc. I tried to contact the developers with no success. The only one that answer was John from Rew and he said he would make it accessible and if I could test it. I said yes but I never heard anything after that and rew is still not accessible and it has been over a year. If I cannot solve anything I just really want to sell safely the Denon 6700h receiver, and the reference premier Klipsch 9.1 speaker system and find some system that is more accessible but I do not know how to sell it safely. I am looking for the chest pounding bass. I do not get it at all. Things were better in the 90’s when they had systems with sliders an I could slide the sliders until it sounded good to me. Maybe I should have gotten bass radiators instead of ported.
