Surround Help

I have a 14x20 room and am looking at getting some new side surround speakers. I'm having a tough time deciding between bipoles and the Polk OWM5s. The OWM5 look to fit better on the walls with their thinner dimensions, but I haven't found much info on those for side surrounds. I'm upgrading from old bose 201s so I'd assume they will be a difference, but I'm not sure how much compared to maybe a pair of bipoles. Are these adequate surround speakers?
