Von Schweikert VR4 III SE vs. VR4 SR4

I'd simply like to add that the VR4 Gen III HSE's bass can be tightened up by adding a handful (or more) of Dacron fill in the bass port of the speaker. This is a technique mentioned in the VR4 Gen III HSE manual, and I have used it with good success. I have no idea how the resultant bass would compare to the bass of the SR, but I like the idea of the ability to tune the VR4 Gen IIII HSE's bass to suit one's room and taste.

Thanks for the fast replies. Here in Europe these speakers are a bit limited. Keep it coming :D

Surely there's been more head to head comparisons between these two by now?
