I was looking at the wiring diagram for the monitor 10s with anticipation of doing the xover upgrades. I decided to look at the SDA CRS+ 1986 Sch.pdf. To my untrained eye it seems like there is not a huge difference between the wiring for the monitor 10 and the SDA CRS+.
Has anyone tried to modify a pair if monitor 10s give them perform like SDAs? Are the xovers similar enough that they would work as SDAs by just replacing and adding some new components and doing some rewiring? Seems like it would be an interesting and worthwhile modification.
