I have to make more room before I can even finish opening the COLO GCS. This is a large speaker rig that mounts around a gaming chair, with a rear section and two adjustable speakers above the seated position.

## Several boxes inside the big one

I unpack the main assembly, mounting pieces, overhead speakers and accessories. There are power parts, two HDMI leads, an angled HDMI adapter and cable wraps to help organize the setup.

I also find separate Cololight lighting pieces in the package. The first job, though, is getting the speaker assembly onto the chair.

## Mounting changes the chair

I fit the upper mounting section, run the straps through and tighten them before lowering the main speaker unit into position. The shape at the top of this chair matters to how the mount sits.

After securing the main section, I connect the two upper speakers and adjust their rotation and height. It is quite a change to the chair's outline, and I can still reach the controls beside me.

## A first listen over Bluetooth

At the end, I connect over Bluetooth and give an enthusiastic first reaction to the depth and sense of sound around me. That short listen is the audio demonstration in this session.

The 7.1.2 label describes the system being presented. I do not verify discrete channel mapping over HDMI, measure latency or run a game test here. My comment about trying it in games is the next thing I want to do, not an FPS or positional-audio result already established.
