Hello, This Is my first post here, however I have been reading and got many good ideas from this forum the last year. Im on my way building a room just for movie and music and I´m having a few questions regarding my speakers. My end goal is having a 7.1.4 setup when I'm finished. At the moment I have a 5.0 setup with Q Acoustics 3050 fronts, 3090 center and two 3010 back. I was thinking of buying one more set of 3010 so the back and rear back speakers are all the same but would there be any point in going for the 3020 instead, and if so, to use as back, or rear back speakers in this setup? Im also going for a sub, but I haven´t decided on one at this point. Im also wondering about the 4 in ceiling speakers, the ones I'm looking at right now are rated 8ohm, but my Q Acoustics are rated 6ohm, will this be a problem and I need to go with 6ohm ceiling speakers or is it ok to go with different ohm here? The receiver I'm using now don't handle Atmos so I will be upgrading it when the room is all finished but I would like to be able to install the ceiling speakers and all the speaker cable wiring now when I'm doing the renovation so it´s all set for the future. Is there any one here who could recommend a receiver that suits the Q Acoustic speakers? (Im having a little eye on the Marantz 7010/7011 hoping to be able to find a pre owned one in next fall, but all suggestions are welcome) Im glad for all the help I can get!
