Hi, I am in the same boat with roughly the same budget (a little stretchable) so closely following this thread. The room size is 24’9” x 14’9”.
Im leaning on the Hisense C1 projector, and Denom3800 for the amp. Rest is still undecided but ive laid 2.5 sq mm wires throughout for an7.2.1 setup, looks like im gonna need more subs. This is going to be difficult in the budget
