Tweeter protection.
I have some extremely rare tweeters that I need to protect. Can
anyone recomend the size fuse I should use to stop at say 100 watts and at 200 watts? TIA |

More information about the setup and specs is needed to help you. Whether you're using an external amplifier or head unit power, you should just match it to the tweeters (less power to be safe as you want to protect them). Also, use a proper crossover, highpass filter, or whatever you choose to control what frequencies go to the tweeter. You could also use an L-pad, resistor, fmod, or polyswitch (a fuse in reality)...etc...etc... John Carstereos.org Bcae1.com -- John |

It's not car audio but I asked here not because the equipment is relevant, but because I figured the question was. So a Carver amp at @ 750 wpc at 6 ohms into Mirage M1 speakers. |

It's a simple matter of applying Ohm's law. P = I^2 * R P/R = I^2 sqrt(P/R) = I So, take the amount of power the tweeter can handle, divide it by the nominal impedance of the speaker and then take the square root of that quotient--that'll give you the amount of current drawn. Fuse accordingly. -dan |

One thing I'd like to point out in all of this is that a fuse is
likely to do more harm than good because you'll be under the false impression that you can do whatever you want with the volume knob and the fuse will save your bacon if things get too hot and heated. If I were you, I'd just set my gains very carefully and don't let any idiots near the volume knob. By using some common sense and by designing/choosing your crossover carefully, you should be just fine. I've had the same pair of MB Quart tweeters in my home cabinets since 1995 and they've endured everything from sound effects CDs to Metallica with no problems whatsoever. I see no reason why your tweets should be any different. -dan |

Figment of your imagination...! Eddie Runner was NEVER here.
BTW, did the RARE tweets just turn out to be some Mirage home speakers? I dont remember them being all that esoteric or rare. plain ol dome tweets if I remember right.

They may not be particularly esoteric, but they are pretty much proprietary. -- "Yes, it is a good thing you are handy, as you clearly suck at being smart." - Herb |
