3db's Great Room (mainfloor townhouse open concept) setup

[3db]

I swapped out the KX-800 deck for a K720 auto reversing deck that I've had in storage. Plays really nice.

The new sofa and chair are in, waiting on a couple of ottomans to come in to complete the room. Did another sub placement/REW EQ exercise. Measurements to follow later but this what the room looks like now;

I redid the sub locations and will upload the pic. Basically the orientation of the left and middle sub has changed with the driver facing the closet corner or back to back. I took three full frequency sweeps with the sub distance of the AVR set to 16.5', 25', and 27' . Although none are ideal, which would be the best setting?

If I had to pick I’d choose 25(red). Can you hear any difference between them? I’m a little surprised the graphs didn’t change very much. That’s a pretty wide trough and I would think it would be audible considering it’s like 15db deep. What happens with different XO points?

I should have kept all my sub distance runs but there were a few distances where the crossover region wasn't too bad but it gave me to bass humps. This room is such a bitch to dial in. I will revisit on Monday.

Have you tried messing with REW's room simulator? It might help a tiny bit at figuring out where things can go to help some of the nulls. It was pretty spot on in my theater, but I've got a square, sealed room to deal with. Still not ideal, but not that difficult.

Here's the new layout of the two subs I mentioned earlier.

I should. Might give me better placement options

Well I gave it another go yesterday running sweep after sweep in 1ft increments from 1' to 16' . Not seeing anything outstanding happening, I jumped to 44' The RX-V1900 has setting all the way out to 80' . Anyway I started running sweeps above that and it got worse looking. I finally settled on something that was a little better than last time.

This room is an acoustic bear which is impossible to tame without excessive room treatments. I'm going to try this again next week.

I received my 2nd AC Infinity fan, an S8 and installed it into the system today and tried to clean up the wiring.

Cable management is always a chore with that many components but it's better than letting everything pile up on the floor. Back of my AV cabinet looks pretty similar.
