I am using mine as a stage monitor, on a mic stand, 1/2 meter to the right of my mic, mic stand, around 3/4m high, it points straight at me and sounds good at around 1/3rd volume.
I have the genuine Mackie version of the cl105a, but the Mackie is 1 killo heavier, needing a full size mic stand for stability, consuming floor space. My cl105a, much lighter, only needs a light cast iron base mic stand, using 1/3rd the floor space of a standard mic stand (less stage clutter).
The cl105a has a few more features than the Mackie, the cl105a has BT + memory stick 'usb' mp3 player + mp3 control buttons & 3.5m mini jack socket more than the Mackie, but only 2 channels, the Mackie has 3 channels, other features are similar, 3 eq controls, master volume.
The sound quality from these 2 is almost the same, both with 5 inch speakers, but the Mackie is much louder, 'loud' is not needed in a close up monitor.
The eq on the Mackie has much more range, but I mostly use eq flat (12 o'clock), eq'd at the mixing desk, so no problems there.
Over all, the (my) cl105 is an improvement for me at larger venues. all connected, it fits into my sound system perfectly.
I think the cl105a is a thomann brand, I have full confidence in thomann products, some I've had for 18 years, mostly reliable and mostly good performers + 3 year warranty :-)
