Alright, I turned off my noisy projector and my phone says 47-52 db ambient noise with the HVAC off. My phone doesn't seem to pick up the HVAC noise, but I can hear it when it's on. If I put my head right in front of the speaker and turn the Vidar off and back on again, I can hear ever so slight of a hiss coming from the mid driver. I would say relatively it's maybe 1/2 as loud as the hiss coming from the woofer which is being driven by the Crown amps. So I have a little bit of noise coming from both amps.
I can't hear it from my listening position over the ~50db ambient noise.
This does really make me want to build something to isolate my HVAC and projector noise from my listening position. I can design that. I might need to add a little quiet computer fan to be sure the projector is venting heat. I suppose I should cut a hole in the ceiling and put a tube up through the insulation and vent the heat into the attic. My only concern would be if it's 150 degrees in the attic in the summer and the fan is off and I let a lot of heat into the room. I have to consider that more. But it'd be an interesting and inexpensive experiment.
I do have two dedicated circuits in this room so my power comes straight from the breaker box and isn't feeding anything but my computer, my monitor, my projector and my sound system. I suppose I could improve that my putting the projector and computer on one circuit and the entire sound system on the other.
I have a Furman DJ "power conditioner" that I basically use as a plug strip and I also have "POWERVAR" power conditioner that I got on eBay maybe 10 years ago or so. I don't know if it's good or bad but it was like $40 used. I can experiment with those things a bit more.
In conclusion, I can't hear the noise from the Vidar in my room while in my listening position.
Maybe you should go to Guitar Center and buy a couple of these Crown amps and run your bass off of them. They had a 15% restocking fee for up to 45 days. The difference for me between running the entire speaker off of the Vidar (in stereo mode) and just running the top end was dramatic. We're not talking 10-15% different, we're talking the difference between a serious high end system and one that was kind of mediocre.
But there is a reason that the Stereophile review for these speakers says they had to bi-amp them with a pair of Levinson 335's to get them to sound good. Would if I could.
