Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.

ATC SCM100PSL needs about 48% more floor or shelf area. ATC SCM100PSL is 60mm deeper, so it stands that much further out from the wall. ATC SCM50ASLT is 169mm taller.
