I agree Russ. I don't think that new units sit in stock at HQ or distributors for very long and I know that the folks at HQ in the plant will be very precise about how they install the drivers.

To say that new DSP's need to be tightened doesn't seem right (sorry Pers)

I would install the speakers, play them for 6 months and then ask the question again.

Rgds,
