My VR-4Jr are in the 152" x 280" room.
The rear of the cabinets are parallel with a "toe" to the 152" wall and placed about 30 inches from three walls.
I do not look at the adjustment value of the ambient tweeter, I simply adjust it to taste. Like I adjust the volume control to taste like the amount of cream I add to my coffee for taste...
Typically left and right channel recording levels are not even, so, reffering to a "number" or setting "Q" is not relative to actual SPL.
I suggest to use your ears not a number when listening.
That's is presicely the why many high-end pre-amp manufacturers do not print numbers on the volume control.
Do you have amount of gas into injection levels indicators on your Ducatti? OK. moving on...
The VR-4jr's are very musical, forgiving and revealing at the same time.
If you have speakers for the explicit point of listening to music, a TIVOLI table top will do just fine.
VR4JR. really don't have a "sound" they are simply a natural messenger for quality recordings.
Ryko recordings do not so good with VR-4JR, as result you should love the music on Ryko.
But Ryko recordings are known for music content more so than recording quality. Thus proving my point,the VR-4JRs., are also revealing.
I love them.
