Decided to go with Epic 60's with VP150 & can't decide on EP350 vs. EP500. Going in 14'x 20' room that opens up in rear to another room, 8' ceilings in HT area. Pushing w)RXV2600 receiver. Is 350 not enough or is 500 too much? Don't want the ceiling downstairs to come apart. Is there that much difference in the two? If I order the 350 will I regret or wonder if I should have gotten the 500? Anyone gone with 350 & upgraded to 500?
Need advice!

Thanks,

Don
