I was looking at the Osprey for my Spatial M3 Sapphires 92db and decided against it. Wasn’t crazy about their restocking fee. Although the Ravens seem to be trending now I wasn’t convinced I would be able to push those 15” woofers. I opted for an Octave because I had a dealer close by and haven’t looked back. I wound up with the V70 Class A. The Octave is stunning and can drive virtually anything. You might want to check them out.
