Best garage speakers


I need two good garage speakers to fill 900 sq ' and to sit against a 30 foot wall. Eyeroll, I know, this is a sophisticated forum but help an old guy . We 4 guys have a few whatevers and listen to good tunes after fishing in northern Mn . I have a Yamaha RX-V992 receiver. Bookshelf or floor speakers are fine. I have room for a sub too..I'll spend up to $400-$500 for a used set on Marketplace or this site. What would you look for to buy

Thanks for the help on this. I bought a pair of Forte ii's. The Forte's look like new but haven't had any of the updates I've read about. $600 was a little more $$ than I wanted but their fanbase indicates I  have heirlooms that can be passed on for generations. So now it seems they deserve an amp to validate their sound capability. I have a Yamaha RX-V992 up at the lake. I'm going to try  find a better power pairing for it . Maybe a tube amp. Any suggestions on an amp that shows up for sale often that I could watch for. Thanks so much to everyone on this.
+2 for Tekton......Finally I can agree with a posting about this brand...the garage is the perfect place..you scratch a cabinet who cares (doubt anyone would notice)..mess a driver ,simple fix as they use off the shelf stuff...yepper, a perfect garage sleaker
