I’ve heard other Sonus Fabers in person and many others in Calgary high end shops. They do sound really good in my experience.

RRlev was any of this helpful?

To mount the OW center speaker I would use two seperate QRDs and leave a gap between them. Notch the QRD where it joins at center to accomodate your CC. Leave small gap around the speaker all around. Build depth same as mounted speaker. 4.5” or so. Ports should be unobscured.

This is something you can add down the road. Use foam. Way lighter.
