My only problem is that the Swan 3.1s are huge and there is no way they wall mount with my space limitation. I haven't measured the 3.1s lately but one 3.1 is about the size of ten QS8s. So they stay up there unused, used if it makes sense or I will sell them.

To get to a 7.1 I will need new speakers but it sounds like you suggest to put the QS8s on the sides and get new rears. I could get the M3s or QS8s for the rears but the M3s look better with my tight set up.

Also, I now only have 5.1 due to the old AV and I want a new AV receiver with switching and 7.1 minimum, etc.
