Anybody know these speakers? I just aquired a pair of these.

They are making a rattling noise in the woofer portion.

I talked to the factory today.

They said the speakers probably need to be reglued. I am wondering why I couldn't reglue it.

Anybody got any firsthand knowledge they might like to let go to a dumb Redneck film collector?

Even with the rattling sound, these speakers dance circles around my ancient Advent speakers that are currently in the theater.
Q: What do you have when you use fine speakers with a home-made audio retrofit 1940's 35mm portable with 16mm sound?

A: Wishful thinking.

I think these speakers mounted on either side of the screen in each corner will really enhance the experience.

My speakers became rattly once. I took the speaker off the front and looked inside and there was dog food in there. Apparently mice had been taking one nugget at a time and storing them in there. I guess it was their new house to be. I'd take the speakers off and get some elmers glue and run it around all the enclosure joints to make sure the box has not seperated. If that doesn't do it and there's no dog food in there I'd take the drivers down to the local speaker reconing place and have them check it out. I tried to reglue the dust cover on a 30" electrovoice woofer and found out the hard way that the glue and the speaker cone were not compatable. My 30" woofer turned into a 4" when the voice coil and dust cover pulled off the foam cone.

Magnepans are great speakers. My mother's husband is on his second pair. They do have some problems for cinema applications. They can't handle to much sound pressre level. Due to the nature of there design, (Bipolar radiators) They cannot gernerate the kind of base you ould like in a theatre. They must be mounted out in the room and not alnog a wall. The wall will destroy their sound field.

Thanks Ian.

I remember when these speakers came out. I heard my first pair in 1982. Never thought I would have some. Oh yes, these are 10 years old.
