I agree the FMW can come on strong at times, and a bit "Snobbish". Whether its due to experience, bad day, or anything else is really not pertinent. I tend to sift through anyones BS without feeling personally attacked, and if there is solid and reasonable foundation to their reasoning then I'll give it equal weight in consideration. I, like anyone else, have my rough moments and can be quick to react on this forum since I come here to enjoy a day off from hard work in the military. And naturally, if I disagree with someone and I'm all agitated from work stress I tend to write hastely. Regardless, I've never read any post of FMW's that was not usually supported by some sort of quantifiable evidence, except for rhetoric and banter.
That said, his comments with regards to the Paradigm grills got me to do some investigations. I've really not done all that much, but I've begun a start to it. After all, it is pushed by Paradigm that their "grill covers" make a difference in its intended sound. So FMW is right, wheres the proof?
Well I pulled up another article review that actually did some testing, and though the reviewer doesn't touch to much on the subject here is one comment he made,
The Paradigm Signatures were measured with their grilles removed. For both speakers (S4 and C3), the grilles slightly reduced the treble level but also made the high-frequency response rougher.

here.
The comment suggests that during his testing at some point he threw on the grills and measured a difference. Whether he thought the difference was worth displaying the same data sheets but with the grilles on, or whether he just thought it wasn't central to the main course of the review is anyones guess.
For me, this review gives a little credence to Paradigm's claim, but still fails to offer any fact truly backing it up.
I took a picture of the inside of the Studio 100 grille, and from what I've seen of other grills, or socks it definently appears a bit more unique. Take a look for yourselves, and any comments are definently appreciated. I'm interested in getting the truth of it.
Also this link
here, for another review on Paradigms where the reviewer offers significant commentary on the grill, but again, no data. Specifically he notes an almost 180 degree difference from with the grill off as to when it is on.
I checked out Paradigm's website and took a look in the Q&A section, one of the questions there was;
Q: Should I play my Paradigm® speakers with the grills on or off?
A

aradigm® and Paradigm® Reference speakers are designed with low-diffraction grills that minimize interference from enclosure edges. These grills also incorporate a Controlled Waveguide™ to ensure superior wide-dispersion uniformity. As such, they are meant to be played with grills on.
It seems to me, that if you can design room additives that can affect room acoustics then its not too out of the realm of possibility that you could design a grill to have an impact on the sound being emitted from the drivers.
I've also E-mailed Paradigm to see if I can get a response and perhaps some data on this claim, so maybe soon I can post what Paradigm has to say in its defense of their grills.
