The Bose speakers are 2Ω and the sub-woofer is 0.5Ω This should give you an idea of what to look for.
It has been said that generally Bose uses relatively poor speakers and influences the sound with a lot of modification at the upstream end. This may adversely change the sound output if you install a high quality speaker in their place. This is all hearsay, as I have no personal experience with (other than the Bose self-powered sub I connected to my non-Bose system) testing audio outputs on this system.
Besides, I'm old and only listen to talk radio, except when I don't. 🤓
