I'll first compare them directly to the CG4/24, which I still own and use nearly every day...and then compare and contrast with some other random speakers I'm familiar with, including my Magnepan 3.6r's in my main room. I really don't have much interest at all in upgrading the CG4/24s, but then when I saw that the new line is also slightly higher end, it did pique my curiosity. I tend to have a love/hate relationship with most box speakers, because I'm a transparency junkie and once I adapt to boxes, I start *hearing* the box. But RSL did an amazing job with my current speakers, and they sound as transparent today as they did they day I bought them, which I find very impressive. The only other box that accomplished that in my home was the DeVore Super 8s. So I'm very much looking forward to giving these a listen. I do also have a pair of 3s here, so I'll probably pull them out and offer a quick side note on the differences, also. They do struggle to fill up a room, I agree with you 100% on that. Hopefully the new batch ships soon.
