Willem sir, you're VERY fortunate to have rooms able to take four ugly boxes plus a pair of satellites with supposedly few issues from the people you share your home with (I believe you have an even larger room with large-model Quad ESLs in it?) and maybe, many posting here also have large rooms not troubled by wires and boxes cluttering up the living space everywhere. I've recently had to change my speakers back recently for visual and bass-extension reasons (boom outside the listening environment), and sit these 1974 examples back on the 9" trolley stands' the model first came with. The visual side here is significantly enhanced as the slimmer profile and lower height suit the room better visually and the gentle roll-off below 80Hz these refurbished old speakers exhibit, doesn't upset the house acoustics in general. I play quietly these days and it's currently mostly speech (audio plays) currently, so subterranean bass is irrelevant.I am happy with my SB2000 (the two other subs in my system are a sealed B&W PV1d and a sealed Kef Kube 8b, so rather a mix). I never had any problems with my SB2000, but it is pretty large and ugly compared to the other two. So its sits in the front corner, behind one of my large main speakers (Quad 2805). It is the most powerful of my subs, and benefitting from the corner reinforcement it is responsible for the deepest bass (down to some 15Hz) in my large room, as per advice from Earl Geddes. Equalization is by MSO/miniDSP 2x4HD. This is as far as my experience goes, other than that I am convinced that subwoofer sound quality is largely a function of the room rather than the sub.
Enjoy your sub(s) and extensive eq and so on if you're able to do that
