Does speaker-level input to sub by pass its electronics?

Um, no, and if you did bypass them you'd end up with no signal.

Besides, the servo itself acts to reduce distortion, so no idea what it is you are trying to accomplish here.

Can't you run the sub using the speaker output?
And use the subs high/low pass functions?

I've used HGS-15s & 10s for years, but not with high-level input.  It's the high-gain servo function I want to preserve.  I'm not familiar with how high-level input functions.  A local is selling an HGS-15 that I might use with the Ayre A7e to supplement KEF LS50s.  I assume I just add a second pair of speaker leads.  The other possibility is a REL T/5i or T/7i.

My primary setup has a pair of HGS-15s that supplement KEF Reference 1s, and use a pair of SMS-1s for acoustic room correction.  I also have a pair of HGS-10s that I hope to try in a distributed bass setup.

There’s no part of that amp you want to bypass.

If you want to start modding or DIY'ing a sub, consider making your own from scratch.
