My current set up, using 2xFM8's. Put high density foam between them ("Sound Addicted - Studio Monitor Isolation Pads") and I assume that's adequate vs say IsoAcoustics products which can add costs quickly. Thoughts/opinions there?
I found dual mono setting on base management was preferable to stereo subs to my ears, so leaving the setting as dual mono. Having ARC Genesis and base management via the Anthem integrated makes it much easier to set up/blend for me. As one can see, limited in space and must follow WAF on that one, so the FM8's checked off all boxes there. They're almost exactly the dimensions of the stands I was using, and had one sub in the corner, now I'm finally doing dual subs. I have never tweaked the ARC settings to personal preferences myself, tend to run it and use the recommended EQ they advise. See attached ARC pre and post settings. Quite the mid range dip and peaks there.
So far, sticking to 80HZ x over but will experiment at some point. Right now, wanted to get used to the much enhanced base output I'm getting from the dual sub arrangement.
I know it looks very reflective, but just out of the photo are rugs, couch, large fluffy dog beds, etc. Not perfect to be sure, but as a shared space, best I'm gonna do.
