They look well placed the way you have them I would suggest giving them more break in time and continuing to experiment with small moves. Great looking room BTW you should fill the gear out on your system.
Cornwall IV speaker placement guidance
I have a new set of Cornwall IVs. The room is 20' by 30' and the speakers are on the 20' wall due to other room layout constraints I'm not able to place them on the 30' wall. I know these are designed to be able to sit much closer to the corner and wall than other rear ported speakers, and I see lots of information online showing them very close (within 6 inches) to front wall and sidewall, but I also see opinions stating they sound better if pulled out 2-4'. I'm about 100 hours in, and have had them where they are now (photos added to my profile) and pulled out from wall. They sound great anywhere, but I do notice more low end the closer to the wall. Any feedback on these specific speakers in terms of proper placement is appreciated!
