Fuse for SEAS Millennium T25 CF002-06 Tweeter.


These fairly expensive tweeters blow out more easily than any I have used. Fortunately replacement voice coils are available, but it's a damn nuisance. When I ordered new voice coils a while back I asked Madisound what fuse might be appropriate to protect the tweeter, but they were pretty skeptical that any fuse would work.

Good news, sort of. A 1 amp slow blow works. It took a real blast from some experimentation I was doing to blow the fuse, but it was the fuse and not the tweeter.

Trelja...I have NEVER blown any tweeter, except these. The mishap did not occur with normal listening to music, but rather during some testing and experimentation that I screwed up. My fault all the way.

As to sound quality, I can detect no difference with the fuse in. This is hardly surprising since the fuse is a few tenths of an ohm and the crossover includes a tweeter padding resistor of 2 ohms.
Trelja...By the way, Madisound is out of stock on replacement voice coils. I wonder why :-(
Eldartford, at this point, if I had experienced what you did in buying these tweeters, I'd be dealing with Seas as opposed to Madisound.

It sounds like your experience heretofore has been the same as mine, so there may be something to this particular tweeter. At this point, were I to need to resort to things like fuses, I would be investigating tweeters from Vifa, ScanSpeak, Dynaudio, Focal(getting out of OEM, but there are a glut of them in the market, and supposedly will still supply autosound), Triangle, etc.

Personally, I was never high on Seas tweeters, for sonic reasons, but I have a lot experience with their midranges and woofers. Have nothing but the highest praise for them. The Millenium tweeter was the first line that I was actually interested in, though we opted for Vifa and ScanSpeak Ring Radiators - perhaps it was a fortunate thing...
Trelja...Yes I do think these tweeters are more delicate than most, but what I did to them was far beyond normal use. I suppose the lightweight coil enhances HF response. I have no complaint with SEAS, except perhaps that they should have recommended fusing.
I'd say the Spica TC-50 tweeter (Audax) takes the prize for easiest blow. At least the way I used to drive them at those wild 1980's parties with that Adcom GFA! I used to go through Spica voice coils the way I go through Ben and Jerry's ice cream now. They'd always blow on the wire lead-in before it entered the actual coil, and I was always tempted to try just reconnecting them with a dab of solder. John Bau was kind enough to sell replacement pairs at cost. I used to keep a personal "inventory" so I wouldn't have to wait for them to arrive by mail from New Mexico. In fact, I'm still keeping a couple, just in case I pull the TC's out of the storage room someday.
