Installing Bucket Magnets



Hey folks, im getting ready to install some Bucking magnets in my JM Lab 707s and a pair of Velodyne Subwoofers in order to shield them for the TV.

Looks straight forward, epoxy the magnets to the rear of the drivers.

Has anyone done this before? Any complications you have come across that i should know? Any advise?

Thanks!

This changes the electrical parameters of the drivers which needs to be accounted for PRIOR to the final design of the speaker. Proceed at your own risk. Sean

Why not obtain some mu-metal and install a layer inside the cabinet on the side facing the TV? Minimal changes to driver parameters, less loss of internal space than large magnets ( which nobody else mentioned and will change the tuning of the box ) and probably more effective overall.

One question though: Why are your speakers ( other than a center channel ) and subs so close to your TV that they cause problems? If the speakers are that close together, there's no need for a center channel as there is no separation from left to right as it is. Even with the 55" RPTV that i have, there's not quite 48" from side to side. While a larger TV would space them further apart, even 5' is too close together for stereo, let alone HT use with a center channel.

My guess is that you would benefit more from re-positioning your speakers than doing anything else to the system. The good news is that this is free and completely reversible if you don't like the results. Sean

I know that Michael Percy sells some shielding kits, but i don't know exactly what he offers or how expensive it is. Doing a search on the web might turn up some "non-audiophile" suppliers with both a wider variety and slightly better pricing. Sean
