I post pictures of my current systems here as background information. I will place a link to this in my profile.
First, vintage Sony system. good power, good bass, but too boomy and the large speakers are on top of a large shelf because there is no place to put them. They are currently aimed at the topmost part of the opposite wall.
This is the system targeted for replacement by a DIY system.
Edit : The speakers are these as far as I can figure out (could not remove the grille)
