Hey guys I recently moved into my new house and have a dillema...I'm finding my EP350 just doesn't do the job - my room is roughly 20x18 with a sloping vaulted ceiling that is 20ft at the highest point ant 10ft at its lowest.

I was considering getting another EP350 to have 5.2
Would this be a viable solution? I am also open to upgrading, however my budget is limited to around $1100 and of course WAF is a factor - any suggestions?
