Which shape of cabinet gives a better image?

[umut1001]

I’m looking for better sound imaging along with more accurate sound reproduction, similar to what is described on this website:
[https://www.thespeakershacks.co.uk/.../eclipse-td510z-mk2-speakers-review.html?m=1).

My listening room is approximately 25m². The distance between the two speakers is about 2.5 meters, and the distance between me and the speakers is around 3 meters.

In terms of cabinet, should the question be, what shape gives the least amount of diffraction? or the best off axis performance?

" I would like to suggest that "Which shape of cabinet gives a better image?" is not the ideal question to start with.

He might say, which cabinet design philosophy leads to the widest sweet spot.
