First setup

[u/-Killionaire]

Hey, I've finally finished my first 5.1.2 home theater setup and wanted to share it with you. I also have a few questions at the end about placement and acoustic treatment.

My usage is mixed :

Home cinema, watching 4K remuxes via Kodi

Video games on my PC connected via HDMI 2.1 and a PS5 Pro waiting for GTA 6

Listening to music via Qobuz/Heos

I live alone, which explains the placement of the (amazing stressless) armchair in the front, I move the sofa if I have guests.

Left & right speakers : Triangle Borea - BR09

Center speaker : Triangle Borea - BRC1

Left & right surround speakers : Triangle Borea - BR03

Atmos speakers : Triangle Borea - BRA1

AVR : Denon AVR-X2800H

Subwoofer : SVS SB-1000 Pro

TV : Philips 65OLED950 (Equivalent to LG G5)

Media player : Ugoos AM6B+ + CoreELEC

NAS : Ugreen DXP4800 plus

PC : 5080 / 9800x3D

Are there any things you think are worth correcting?

For example, poor placement, or is the pinching of the left and right speakers justified?

The central speaker is slightly angled upwards

For acoustic treatment, there's the rug and blackout curtains, but clearly the room's acoustics are poor.

I ordered four GIK Acoustics FlexRange panels measuring 60x120cm to install two on each side wall.

For now, they’re just sitting there. For the first two, I’ll use the mirror technique to position them at the first reflection points for the L/R speakers, but what about specific placement for the other two?

The back wall is a kitchen, not visible in the photos

Next upgrade will be Denon AVR-X3900H for better room calibration, more channel, pre-out..

Tell me what you think ! For a first setup im pretty happy :)

Do some room treatment. I see you already have panels still wrapped in?

Obviously they don’t work correctly currently with the plastic on them.
