The attached is an excellent explanation about tube gear and speaker matching. He explains it far better than I can. A tube/speaker mismatch is a classic mistake that you want to avoid, it’s expensive and frustrating. I don’t know how your speaker and amp will perform together, but it’s important to understand the issues involved and what to listen for before you purchase. Good luck and let is know what you decide.
