I have a chance to listen to these fine speakers several times at a friends house over the last couple of months.
I think that from the lower octaves through the midbass and lower mid they are exceptional. As the sound moves through the mid to upper mid there is what I call a bit of a hollowness or slight honkiness. I find this common with some speakers that err slightly on the clinical side of natural. I have heard these speakers with different sources and amplification and this is part of its inherent sonic signature. This isn't a dig. They have many great virtues; Speed, clarity, aliveness, pace, smoothness.
We compared them side by side with a pair of Source Technologies 2268's (manufactured on the east coast)and we both agreed the blend between the mid and tweeter was more seamless and natural and there was a greater sense of a whole musical event with substantially more acoustic from the recorded venue coming thru in that region with the 2268. The music had more of an "event" sense as the VR4jr's were faster with greater emphasis on dynamics and impact and clarity. The 2268's were equal in clarity.
Both are tremendous.
At the end of the day it was apparent that the more seamless crossover through the mid of the 2268 was allowing more mid info to come through and a more natural harmonic sense of space and openness. The VR4jr's were open but not as naturally so... If that makes any sense.
The jr's do things at there price point that are exceptional, but for me the bit of a honkiness drives me nuts. I've heard the same thing from the Red Rose speakers. I believe that a good 60% or so of the speakers at this price point suffer from this problem.
It's a combination of resonant peaks of a driver along with using certain metalized caps and of course driver/s compatibility. Anyway the jr's are very special but they have too much of their own sound where you want it least.
