Default Vertical MT, horizontal woofer

What are the implications of a driver layout such as this (see attached, from K&H O300 ) FWIW this is a highly regarded speaker in electronic music circles.

Will the stereo image jump out to the sides when it gets lower in frequency, or will the wavelengths be too long for it to matter? What about baffle step issues?

This is an 8", 3", 1" design, would there be any issues using bigger drivers - say 12", 6", 1" or 10", 6", 1".

Thankyou -

So the centre-to-centre spacing of the woofer and mid won't cause lobing issues with reasonable crossover points, however I'm still not sure what that means for the stereo image? Will I be able to 'localise' the woofer below 450hz?

Too bad they don't provide mirror image boxes.

Looks like they make left and right variants (link on right) however this is merely inspiration for my DIY tinkerings.

Interestingly their larger monitors have a removable baffle around the MT section to allow switching between vertical and horizontal.
