I have a pair of Magnat MSP 110's & 120's. I know they are fairly old, but they sound great and to get speakers that are as good or better would be way too much cash for me to spend right now. Anyway the tweeters are gone on the 110's. Anyone know where to buy replacements other than directly from Magnat in Germany? And, does anyone know if it is absolutely necessary to use their tweeters? Why not a scan-speak or another manufacturers'? Thanks alot, Rob.
