I don’t think there is any way to bypass the amps, other then maybe internally moding the speaker and bypassing it.
After hearing the Summits I don’t know why anyone would want to? The integration between the woofers and panel are seamless, you may think the ascent is very good in this area, but after hearing the summit I think you will agree it’s damn near perfect. I think most of that seamless performance has to do with the mono amps.
But I could be wrong, all I know is what Martin Logan did with the summit works and had taken the summit a few steps closer to perfection, changing the summit from what it is could undo that.
I personally love the Summit’s just the way they are.
