Is the 8" woofer section completely physically isolated from the rest of the speaker? If not, then the internal volume of the 1ks, even with the woofers inactive, would be different from an 850s, wouldn't it? And, if that is the case, wouldn't a different internal volume mean a slightly different sound? I hope you understand that I'm asking here, not challenging. I do not know the answer to any of these questions.
