ATC and Loki

Ideally you will connect the Loki between your preamps outputs and your power amps inputs. This is fairly simple if you have separates. If you have an integrated, you will need to use the pre outs and ins if your amp has them, otherwise you will have to connect it between the source and amp. After connection you just adjust each knob until you reach your desired sound profile.

The Loki appears to be a very wide band, very low "Q" tone control comprised of four filters, that per the diagram on the units front face plate appear to be shelving style filters. IOW each knob is going to cover a very large range of frequencies.

M6, did you get the loki plus, new from
schiit?  They’ve been out for 6 months (?) and still are.  I wouldn’t hold my breathe…

Are you trying to tip the highs up?  Point the ATC’s directly at you.

Correction, looks like you are trying to tame the highs…. I’ve had the smallest version of your speakers, the little babies, but they had the same tweet andI would never describe them as bright,

sometimes an overlay aggressive midrange will make a listener think “bright”.

whats your toe in like? How close are they to the walls?

I’d still try pointing them directly at you and pushing them closer to the wall behind the speakers. This will increase bass and highs and can tame an aggressive midrange giving you more of what you are looking for.

Thanks, all. The unit is supposed to arrive today so I will play around with some of the variables.
To reiterate, I have two concerns. One is low listening levels and the loss of bass to my ears as a result. Across the room from the speakers, a wall of windows have got to be Brightening the sound quite a bit.. We will see…

The downside to low level listening to accurate speakers is a lack of bass.  It only sounds right if you're listening at levels closer to realistic for a real performance.
