That’s why i went with atc/no port...lower end im little room way boomy...placement and room treatment is everything...got mine placed as well as im ever going to get...friend came over for a listem his jaw dropped...right from the start he commented that they were placed really well/even toned it sounded...do have bass traps in each corner of the room/no side reflection...thats it since i have axis pointed pretty much right at me...fwiw.enjoy!
Will add that my room is the smallest room (12.5’ by 10’) I have ever had to work with...I was cursing the audio death sentence...much to my chagrin...could not be more surprised.
as it is right now its the best sound stage I have ever had...its all there...really satisfying to nail it as close as I did...
