I recently bought 2 Monitor 70's, a CS2 and got the free Polk 10" sub. I received 2 RTi A1's for the rear surrounds as a gift. It all sounds really good but my issue is the size of the Monitor 70's. They're just kind of too big for my space. I'm considering returning all the Monitor speakers and the sub, keeping the RTi A1's, and getting 2 RTi A3's and a CSi A4 and then buying the entry level Hsu sub for $399. I like the way my current setup sounds and I'm wondering if people think the RTi setup would be a step up or back or what? The "new" setup would only be a a couple hundred bucks more. I have an Onkyo 705 and it is mostly going to be used for HT. Would love to hear any suggestions or opinions. Thank you!
