Driver or Port ?? Which height should be optimized.

Hello there... I got a (maybe dumb) doubt...

I'm going to flushmount ATC SCM 110 monitors so I will have a main in wall system and a nearfiled system

Room is 310 cm high.

I would like not to tilt them in order to have a larger spot and easier design...having midrange ad 160 cm from ground makes me respect 5° maximum off axis allowed from ATC manual.

I would like to optimize woofer height in order to avoid sitting them on nulls/peaks..

In this case I will end having :

LF DRIVERS 140 cm from ground
LF PORTS 115 cm from ground

Drivers would be very near to 155 cm ( half height.. ) maybe the worst position ever...

Ports are in a quite good position...

The question is ... the sources that couple with room modes are DRIVERS or PORT ??

(i'm quite sure the answer is drivers... but I'm hoping are ports )

I was considering also putting monitors upsidedown.. this will result in :

MIDRANGE 160 cm from ground ( so same position as before... is ok for directivity )
LF DRIVERS 120 cm from ceiling (good..)
LF PORTS 95 cm from ceiling (quite good...)

Mounting ATC upside down appears to be a good idea... but tweeter will be 145 cm from ground.. so I'm bit worried that can be a little bit covered and disturbed by nearflelds...

Consider that form ATC manuals acoustic center is coinciding with MIDRANGE

See image to have a rough idea..

Thanx to anyone who can give me a suggestion !!
