Sorry A'goners for my delay in my last posts re the Def4s, but "real life" intruded over the last week. I've found that as I've gotten older, and family/business issues become more serious and intrusive, I more and more really crave the serenity that a great audio system gives me, and my stress can melt away while listening to my regular diet of 3 albums a day.
Anyhow, covered the FRDs mids and bass, last thoughts are on treble. Here I'm a little less decisive in raving about the 4s. This is only since previous comments stated it to be qualitatively a leap beyond the 2s whereas in my room it is more of an evolution.
What I always loved about the 2s was the absence of the sort of spotlit treble evident in so many high end spkrs, and I do feel this characteristic isn't changed dramatically by the 4s. Now I know that this is a flavour imposed by the FRDs, and since the mids are SO much more transparent and delicate in the 4s this is likely what I'm experiencing with the treble. Again, high frequencies aren't overt until dominant in the program material, and then the music soars into the ether.
So my final conclusions. This is an AMAZING speaker, and a leap beyond what the 2s were able to offer. Most importantly, the new FRDs really introduce an electrostatic like transparency and delicacy to the addictive tone dense sound that we all love about the 2s, with no down side.
Bass is really impactful, more tuneful and much more integrated into the whole. Treble is less noticeable as a step up, but this may be the point: the FRDs covering it are so brilliant on mids on up that this character into the highs is all part of a subtle blend.
I was SO fearful upgrading sound unheard, but all has been allayed. The 4s are an absolute giant killer, imho really treading onto the territory of uber spkrs over 4x the price, but maintaining and enhancing the addictive tone dense Zu sound that no other spkrs seem to approach.
