ATC and Loki

Who are they? Which ones have you auditioned, set up and powered properly?

Exaggerated bass at any volume, which will compromise sound quality at higher volumes, is not the solution.

For those that can not or will not solve the problem properly, I would much prefer a good equalizer which can be adjusted at low volumes than a speaker that is designed to have exaggerated bass at low volumes.

BTW, another equalization option is a very good sounding 6SN7 based line stage with useful equalization, especially in the bass region and fun spatial controls both of which can be bypassed. Black Ice Audio Fusion F360. They also offer these circuits in a stand alone device that can be inserted in your tape loop, Foz SS-X.

Just be aware that such things are not approved by the audio police.

How do you properly solve the problem of speakers not sounding right because they're not being played at accurate volume?  

Avoiding questions asked by posing other questions is typical on these forums.

I'm trying to make an abstract argument rather than personalize this and I don't think my personal experience is all that relevant.  I've got a few systems.  I've got ATC 110s in a family room system, Thiel 3.7s in what I'd call a den I guess, and also some Vienna Acoustics Mozart Grands I use as computer speakers.  

How do you properly solve the problem of speakers not sounding right because they're not being played at accurate volume?  Our ears don't hear all frequencies equally so what sounds right at 90db sounds bland at 80.  I agree that EQ is a good way to mitigate this.  My Thiels sound better at low volume than my ATCs.  I'd guess because there are design tradeoffs between speakers that need huge dynamic range and those designed for moderate max volume.
