Hi. Did a search for VM1 and found a lot of info. Not any that answers my exact question. I wonder if anyone can help. So which sub to partner the VM1's. They'll be used 50/50 for music and movies, being fed from a Sony STRDB930 receiver. An oldee but a goodee! I want the sub to be as musical as it is muscular. The catch is, having spent so much on the VM1's, I am limited to spending as little as possible on the Sub. I want to go a step up from, for example, the REL Quake. I'm not bothered about the make as such, just need something that will be good enough for VM1's. Therefore, any suggestions on what and how much, please?
