Hello, I recently purchase a set of 70-RT polk in-ceiling speakers for my back surround. I also purchased a set of the RC80i speakers to compare them side-by-side to the 70-RTs. I liked the 70-RTs better. However, I couldn't return the RC80is and I now have four in-ceiling speakers.
This is my setup:
Front RTi A1
Center CSi A4
Receiver Denon 2113CI
Since I have an extra set of RC80is, I have thought of connecting them to the 70-RTs in series or parallel to improve the sound ambiance. I know my Denon 2113CI is a 7.1 receiver and I could connect these two extra speakers for a full 7.1 surround sound. But I'd like to use the extra two channels to power two Bose 51 outdoor speakers as Zone 2, and keep my indoors surround to 5.1 (I believe I don't have enough space to justify the use of 7.1 (living room is about 14' x 14') and I really wanted the receiver to power two patio speakers).
A sketch of the setup I had in mind looks like this:
Would this be possible? Would it improve or hinder the sound quality? What about running them parallel instead of in series? I have read many threads on this topic and have heard mixed opinions about this. Any information on this setup would be appreciated.
