BA VR-975 Passive Radiator help
I have a pair of Boston Acoustics VR-975 floor speakers. They have a
10" powered sub with a 12" passive radiator in each tower. Yesterday, watching Chicken Run with my son, one of the 12" passives blew out. I took it apart and there is a metal cylinder that is supposed to be attached to the membrane. (Its now unattached). Is this something that I can reattach myself and if so, what kind of epoxy would I use? Or should I contact Tweeter or BA? BA calls these "tuned" radiators. So if they can be done "DIY Style", any advice? BTW, I am a complete novice at this.... Thanks |

The problem, though, is that you won't be able to get the tension correct. You can play around with mounting and remounting it, tapping on the good one and the bad one and adjusting the tension until they sound the same. But it should just be a lot easier to call BA and order a replacement passive radiator. They should stock them and they will come on a frame pretuned with the tension they are supposed to have. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I will contact BA on Monday. People tell me they are very helpful. I live less than an hour from them. |
