Why don't you look into the Dave 12 G3 2.1 system with 12' subwoofer by LD Systems? $500 shipped. An amazing value.
https://www.amazon.com/LD-Systems-DAVE-1...sr=8-6-fkmrnull Musicians' Friend still sells it for $999 and fantastic reviews on this German website by users;
https://m.thomannmusic.com/ld_systems_dave_12_g3_reviews.htmI have a number of speakers by LD Systems. They sound good.
I might add that the 2.1 system will be a "real" PA system in comparison with the Bose you had been using. I stay away from Bose all together for a number of reasons. One of them is I feel that with Bose I get much less for what I pay.
