Did Junior replace the VR-3?
When we started with VSA the main VR speaker lines were as follows
VRs 1, 2, 4jr, 4HSE. The 5 HSEs and 7 HSEs had just been discontinued
later it became
VRs 1, 2, 4jr, 4SR then joined by 5,7,9 and 11
Todays VR matrix consists of
VR 4SR, 5 Anniversary, 9SE and 11 SE with the 4jr Anniversary and VR-77 set to join the line up very soon.
Logically even in cabinet and driver size and complement one might surmise that the Jr is today's VR-3 so it was never killed at all just renamed to reflect the change from a single baffle design to a double stack like its dad the SR and the Gen II and Gen III before it.
The VR-3s and 3.5s are great speakers. One of Alberts favorites in fact. Over here they are collectibles.
