I have a set of H-WO's. Serial# 97U115 & 6 I recently acquired them. 1 Has a blown tweeter. I just ordered a pair of diaphragms. I have not opened these speakers yet. I read somewhere online (can't seem to find it again) about using a 1 amp fuse to protect these K77 tweeters. Do these speakers have fuses inside? (never seen that before) If not, are people installing them inline somewhere inside, or drilling and mounting fuse holders accessible from the outside?
