Home Theater Setup Questions

I am thinking about purchasing a pair of KEF Q1 Metas to start a new home theater setup.

I currently have an Onkyo HT-RC460 and a pair of Bose 301 Series II with an old Yamaha subwoofer.

Are the KEF Q1 metas a good choice? Will they pair well with the AV receiver I have or should that be replaced too?

Thinking about also getting a new JBL Stage 200P 10” subwoofer but I am open to suggestions.

Hoping to keep the whole setup below $1000.

Thank you for any help in advance.
