A single 8361A will play *at least* 118dB @ 1m in the midrange, and in-room losses are typically 4-ish dB per 2x distance, so with two speakers you can definitely play a lot more than 112dB @ 3m. It will be significantly less than that in bass, and heavily dependent on how much boundary reinforcement the speakers are getting. The speakers are specced for 109dB average below 100hz and 118dB average 100hz-3khz (in half space, both). Proper testing has always confirmed their accuracy to date.
To effectively test this, you need to run a slow sweep and see at what frequencies the speakers are actually limiting. Playing music and guessing isn't going to work. If you're being limited by the output below 250hz but above sub cross(which is very possible), then the only fix is going to be W371As or (possibly) moving the speakers to get more boundary reinforcement.
All that said, 112dBC on a slow SPL meter is
incredibly loud. In my testing, slow averaging underrates real peaks by at least 10dB, or even more. And dbC also cuts real values below 100hz even further. I've never played any music louder than 95-100dBC on a slow SPL meter, and even that is typically too loud for more than a few tracks before turning it down. Except I guess for weird things like
Recondite - Pour where all the output is low bass.
You can disable the lights in GLM, not totally sure if it prevents a red light, but it's worth a try.
