There seems to be a fair number of S8 owners here defending the model. Open one up and snap some pics of the internal cabinet construction. Seriously, I have searched for any pics or mention online about how the cabinet is actually constructed. Short of this IMS feature, I've been unable to find any mention of the acoustic engineering designed into the cabinet. If the S8 faithful want to win over the skeptics, open them up and show us the internal bracing.
Actually, I think the only S8 owner whose speaking up on this issue is me

The others seem to have more sense than I.
Why should an owner feel the onus to disassemble their speaker? The only reason that I continue to go on and on about this is because I'm quite bothered that Chris would presume the S8's - and the many other floor-standing speakers he impugned without mentioning them directly - have problems with resonances simply because their designers do not share his particular view on what constitutes and audible resonance and how best to address it. The thread caught my eye b/c it mentioned the speakers that I happen to own but I'd feel this way no matter which brand he disparaged in this manner.
Chris cites his use of double-blind testing and use of measurements as evidence of an impartial, science-based approach to speaker design. Well, take a look at Paradigms website and read the fairly detailed explanations of their approach to speaker design, use of the NRC in Canada, development of their own anechoic chamber, use of DBT, and you'll see that they also take a very engineering approach to designing speakers. They are not like the many "two guys in a garage" outfits or the the smaller companies who have more to say about their furniture grade finishes than the scientific rationale for their designs.
Remember, of the many glowing reviews of the Paradigm S8's - both the v.1 and v.2 w/ beryllium tweeter - not ONE (that I've read anyway) has noted ANY problems with resonances. Yet Chris has presumed them to have them simply b/c he's come to expect this from speaker mfgs.
I'm a little surprised that others aren't also challenging him on his sweeping generalizations.
