Well, that's interesting. Seeing as how I will be upgrading with new speakers in January, and I had been leaning towards the R30M Signature as one of my finalists, this is really timely news regarding the new speaker. Choice is always a good thing!
Edit: Well, snap. Just saw JC's post from yesterday immediately preceding my own, and I don't have the room for as big a box as that is likely to be. But I bet it sounds amazing...
