Thank you Christopher,
I thought about changing speakers but we live in a small town in France and the nearest audio shop is hundreds of KM away. I bought these Missions on the Internet from the UK and some good friends found space in their car to bring them out. They take up, in the box, about the same room as a person.
If I was in the UK I would probably go and do a swap but here is not the same kind of situation.
The other thing about me is that I used to work for R&R bands as a roady (long time ago). I have listened to some famous bands from a distance of 10cm from their Marshall speakers and as a consequence have a pretty limited capacity as far as ears go. I can hear good clean sound, however.
I don't think I could discern a small drop off in quality with an in line fuse in place. The trade off is the loss of music due to a moment of irresponsibility on the night and the weeks following without any music at all waiting for new speakers and also the cost and inconvenience.
These 782's are pretty sweet, by the way, and the people on the end of the phone at Mission have tried to help and are always friendly.
So, any ideas regards fuse protection?
Kind Regards, Burton
