I'm thinking of changing some items around in my home and I thought I'd ask for your thoughts.

If I have a pair of M80's and for the moment say an ep500 would I lose or gain anything by going to two ep500's and a pair of M22's?

I'm currently trying to decide on a new sub to replace my existing one but then thought about getting two. However if I get two ep500's then I definitely don't have room for my 80's.

My room is roughly 16 x 20 which is a living/dining room. The couch separates my room in two, so my living room is about 16 x 10. 70% HT vs 30% music.

Your advice is greatly appreciated.
