Sysopted, now for soundopt...

Ok, Just pulled apart my shelf stereo and put it under my desk, put a set of 200 W speekers behind me and a pair of 50s in front of me, super power, but it turns my monitor funny colors, erases disks while hey are in the disk drive, etc... I don't realy know much about computer sound, so I have to ask this: is there a way to magneticly sheild your speekers?

[BadBen]

If you put your your speaker to close to your monitor or computer, magnic in the speaker will change the color of the monitor and may erase the some disk.

Ya, thakns for stating what I said, how do I magneticly sheild them so they don't (normal PC speekers don't do that)

The only way to shield something from that much field strength is use IRON PLATES! /forum/biggrin.gif You're going to destroy that machine. Distance is another solution-get those speakers the hell away from that computer! I'm suprised that you can still post messages
with that unit. Good luck. ROFLMAO!
P.S.-NORMAL pc speakers don't have to dissipate 500watts of power either. If this is a joke it's a good one. If it's not a joke it's still a good one. /forum/smile.gif
BTW pc speakers are internally shielded.

What kind of music do you listen to? Classical shouldn't effect your disks but rap and hard rock will surely make your monitor mis-behave. Blues and c&w have been known to corrupt floppies.

Only a pair of 50s, not 500!!! No joak, and when stuff went funny, I moved them to the floor. I would rater have them on the desk, music? I listen to metal, but I have not even tried it through this computer setup yet, but a Quake 2 rocket launcher into a wall erases (or realy corrupts) a floppy disk. If I turn the volume way down, to like 3 of ten, then I don't get those problems, except for the monitor, everything is fine. So I have to get plates of Iron? How about lead, those keep in radiation, and they are a lot easier to cut.

Shielding has to be a ferrous (iron based) metal. Can't be lead,aluminum,stainless steel,copper, brass,etc. I guess you could get some thin gauge sheeting and line the inside of those speaker cabinets with it. About 1/16th in.thick I would think. Very strong magnetic flux can even damage hardware! I wonder if some of your problems are caused by the mechanical/acoustic vibrations of that set-up? I'll bet you can shake the hell out of stuff.

Magnetic shielding is done with a form of iron called Mu metal that has a unique alloy composition and crystalline structure. For commonly available materials try sheet iron from a sheet metal shop that is as close to pure iron as possible and as soft as possible. Magnetic lines of force cannot be stopped from penetrating any known material but they can be detoured around whatever you are trying to protect with a highly permeable shield.
