Making speakers “disappear”…..

As per Jim Smith, try to make the distance from Tweeter to Tweeter somewhere around 80-83% of the distance between each Tweeter and your ears when in your listening spot. Looks like a similar formula right above.

All good suggestions above.

Takes work and effort to get a system dialed in, but the results are worth it!

After all the hard work get the best sound by sitting in the sweet spot, not wearing glasses, and keeping eyes closed!

I would like to remind you that there is no EASY answer to this question and Much of any answer must include the design of the speaker. Your speakers design is a Major factor in what treatment is needed in your room. I was just discussing with a friend last evening how my own favorite design has the woofers up off of the floor quite a distance so that the emissions from the bottom of the speaker are not absorbed or reflected by the Floor/carpet. This would be opposed to manufacturers that put the woofer as close to the floor as possible for their own reasons. I am not discussing the validity of where speaker components as place but how it effects the reflective nature of the resultant sound.

Whatever your decision, I would pull in some HFTs from Synergistic Research. I've been playing with these the last several days and it changes the equation on what you can achieve and where you want to place your speakers.

One & Done:  Disconnect & move to another room. ;)

Sorry for the obvious pun...🤦‍♂️
