Audioengine for Surround Sound

I purchased A2+ as a desktop speakers for the home office but was sent two pairs and was also told to keep the extra pair. I’m considering returning one of the A2+ pairs and putting the funds towards A5+ and then building a surround sound system in my living room instead! Can anyone shed some light o xender n the performance of audioengine as a surround sound system? I know I would need a center channel and a sub as well. Completely new to all  omegle things audio so no level of advice is too basic to be appreciated. Thanks!
