I've owned my RM30s for over a year, and from the start they were the finest sounding speakers I've owned. In that time I replaced my amp and pre (now a PS Audio GCC100 ICE base integrated), my player (maxed out Sony/Modwright 9100), added a pair of Carver subs which I veneered w/ granite, and added some room tuning for early reflections. All these added more and more to the already great quality. Yet there was one area of performance that I could not get right. With the CDWG in place, the sound was too laid back overall, no matter what I did to adjust, and without the CDWG, it was too aggressive.
I spent 6 months working this issue every way I could, and I finally tried something I've done with many speakers over the years- I added a rear ambience tweeter. I use an Audax titanium dome tweeter, with a simple bypassed 1uf cap and a 1.5 ohm resistor. I built enclosures for them and with the cdwgs in place the result was exactly what I was looking for. It adds some extra depth and spaciousness, and just enough energy in the presence range. It does not degrade the performance of the FSTs, and that the sound is now not just the best I've owned, but the best I've heard at any price. It is scary good.
As always, while this tweak works for me in my system and room, I make no claims about whether it may work for others. It is very simple to try, however.
