Smart installation Stewart. Presumably no issues with magnet depth as they appear well proud of the carpet surface. Will you be fitting the grills though which I understand are supplied with PC100's as they look a little vulnerable at present?
FWIW I have already upgraded to cheaper Focal Auditor RCX-100 speakers - an improvement in bass but less efficient than cheapo OE Radiomobile. Might be tempted with yours if the improvement is that great, and like the concept of directional tweeters.
Yes I put the grills on after I took the photos and went out for a drive
No issue on depth - I think they are 55mm deep behind but with the thick carpet, there was a good few mm to spare
