I have a dedicated room with 3 x 20 Amp lines of equal length into it. My mono blocks each have their own unfiltered power and my front end is connected to a Shunyata Everest 8000 which is connected to the third 20 amp line. The room is treated with GIK Bass traps and GIK 244 panels & Stillpoint Apertures.

I feel I should comment on the diagonal setup of my room. This is the result of great advice I received from Jim Smith. The main section of my room is almost square 21â x 21.5â x 9â with slanted walls above 8â. There is a short hallway to the right back of the room, leading to a full bath. This is a bonus room over my garage.
Because of this, getting the low end ârightâ was a chore. It was only after Jimâs suggestion, that it became listenable.
More recently, I leaned on Chat GPT to help me interpret the output of REW data to optimize it. That optimization effort is why my two subs are in weird positions. The right sub is behind the right speaker - a fairly normal position - but it is facing away from the listening position. The left sub is much closer to the listening position, in front of the left speaker and facing in the same direction. Itâs a bit of a PIA but it works to fill in a balance the low end. Itâs now tuneful and hits hard.
Also, my room is a bit of a mess and will be cleaned up once my Premier arrives and I get things resettled. I also intend to remeasure the room and see if my Chat buddy suggest any tweaks.
That was definitely the first thing I noticed. I canât say I have seen anyone do this before, but seeing how your system is setup it makes for quite a nice layout. Being canted at an angle like that gives a nice corner pocket for extra cable to run and the audio rack, while it would normally be on the side and require turning to check on, now its just a glance to the left. while the leading perspective of the walls always helps to subconsciously realign your head back to âcenter stageâ. I imagine that was a tricky thing to measure out and get placed evenly with all your references being an angle now.
It wasnât as tough as you might imagine. To start, I laid painters tape from corner to corner defining the center line of the room. That was my reference that guided the initial listening triangle setup.
All changes were then made from that reference. In the end, unsurprisingly, the optimized result was not perfectly symmetrical because the room is not perfectly symmetrical.
I would like to comment on the passing of Jim Smith this week. If any of you ever spoke with him, youâll know what a nice man he was. He was also extremely knowledgeable of our hobby and while he did author DVDs and Books for sale, he was quick to help anyone with his advice.
While speaking to him about my room, as a prelude to him making a visit to set it up for me, he commented that it sounded to him like I enjoyed the setup part of the hobby - which I do.
He then mentioned he had once won a best in show award at an audio show (RMAF?) in a square room and he did that by setting it up on the diagonal. Boom! Free advice that has allowed me to get my room to sound fantastic.
