Has anyone done a crossover upgrade on classic Mirage tower speakers (M-3si, M-1si, etc.)?
I have the M-3si's.  Great speakers, over 25 years or there abouts, never felt the need to trade them in for anything else.  But looking at them recently, there is definitely scope to improve the crossovers and internal wiring.  I also have a copy of the crossover schematic.
If you have, I would love to hear your experience.  Thanks.

We've had customers ask Danny about Mirage speakers, but we've not yet worked on any.
Looking at the Stereophile measurements, there's plenty of room for improvement.
Rebuilding the crossover with better quality will go a long way to improving clarity and soundstage performance.

Interesting.  Soundstage is one area where these speakers excel, particularly off-axis.
The original Stereophile review was quite complimentary and over all the years I have been quite pleased with them.  They are paired with a pair of the Mirage BPSS-210 subwoofers and the LFX-3 subwoofer crossover.
But by now after nearly 30 years (amazed that its been so long), since these speaker get near constant use 15 hours a day 6 days a week, something is going to give -- like those crossovers.  I agree, especially after looking at them (photo follows), the crossovers have considerable scope for improvement and plan to do it.  There just isn't a lot of space on the board for better -- larger -- caps and inductors.  How we accommodate them we be a key part of the solution.
