Set up, hooked up and being used. Couldn’t be happier with it. Big thanks to TomS for posting his build plans and locating this Monacor SP4/60Pro driver.
It integrates so well with my FPX7+sub setup. When I flip back and forth between the two it’s uncanny how the centre mids don’t change. The stereo collapses, the top and bottom end recede, but there’s no discernible difference in the mids at all. It does exactly what I wanted it to do.
I’ll build a better stand option when the outside is warm and less COVIDy, but here it is now in my setup.
