These fully charged ferrite donut magnets have many uses. Can be used to add shielding to small woofers, midranges or tweeters, which allows speaker to be placed in close proximity of picture tubes and computer monitors. Commonly referred to as bucking or cancellation magnets. Simply attach the magnet (in reverse polarity) to the speaker back plate using epoxy or cyanoacrylate (super glue). As a general rule, the bucking magnet should be approximately 1/2 to 2/3 the size of the driver magnet. Limited availability.
