Klipsch Flexus Core 300 being more than twice the price of the 200 - is it worth that?

I don’t have walls on both sides of my TV console - how does the side firing speakers exactly work in that case?

I’m new to soundbar shopping but a consistent trend I’ve seen on posts and comments here is that the Klipsch Flexus series are good. I’m open to Samsung, LG, Bose, JBL anything really, I’ve no biases coming in.
