Acoustics experts - a little help please

Or they are to cheap

gave good advice about consulting an acoustic technician. Most people here are too proud to consult one or just want to try to figure it by themselves

It takes me 2 years full time to understand my room and created the necessary mechanical control devices...it was fun but i was retired and had the time...

 Small Room acoustics, different from great Hall acoustics in his exigencies and conditions,is a very complex matter...

People want simple solutions...

I recommend to study and experiment... It is fun and rewarding...

If you want a specific advice at distance you must consult an experienced acoustician...

I recommend to the OP if he has not the leisure to work it himself and study it to consult a serious acoustician...

If not, you must read, study,experiment... Nobody can replace your ears/brain by his...

@mahgister gave good advice about consulting an acoustician. Most people here are too proud to consult one or just want to try to figure it by themselves spending years sometimes with mediocre results. Jeff at hdacoustics is very good. He can tell you what you need to do to get the best sound out of your space. Good luck! 

The vid is interesting,

Thanks for the video link. Great stuff! 

So I downloaded some audio apps to my phone. One of them measures RT60. I put my phone in my listening position and clapped my hands at both right and left speaker positions. I don’t know if this is the correct way to do this since there were no instructions and I can’t find any online. Anyway, multiple tries from these 2 positions gave me RT60 readings of 0.34 - 0.36 msecs. From my research it seems anything below 0.50 is good. But what does this tell me other than I have an acceptable reverb level? .
