What are these little fuses that come with the component speaker set. I installed my components the other day and saw these little fuses. What are they used for? thanks

 

Do you have a pic of them you could post? I am not sure if they are fuses or if you just think they are fuses. They could be capacitors, or yes, even fuses. If they are fuses they are only used to limit power consumed by the speaker (old way of saving the speaker but still employed by some). It is better to blow a cheap little fuse than to have your speaker get blown from exceeding it's power handling capability.

 

Cant find a pic but they came with the infinity ref. series component set. They are black. They look like a small battery with wire coming from each side. If this helps thanks

 

They say 50 volt bipolar on them

 

sounds like a capacitor. If my memory serves me right, there should be an arrow showing which way they should be wired. The arrow would be toward the speaker. I think. Goes with the positive wire I think. Been a long time, but it's definitely a capacitor.

 

Yes those are capacitors and they serve as high pass filters, meaning they allow high frequencies to "pass" through to your speakers, essentially blocking lower frequencies that the speaker in question will not be able to reproduce properly. Any driver(speaker) will be capable of reproducing certain frequencies, based on design and physical limitations. So it is necessary to keep out those frequencies that do NOT fall into that category. That's why you see many different sizes and types of speakers.

 

Typically, crossover capacitors do not have polarity - they are just installed in series with one of the speaker leads...

Bipolar indicates no polarity. Be sure to install them, or you may suffer tweeter damage...

 

okay so these need to be wired with the positive wire on both speakers? Where should i install these? i am pushing these components with an amp and was just wondering where to install? Thanks

 

Usually they are soldered directly to the speaker itself. One leg to the speaker, the other leg to the speaker wire. Doesn't matter which lead you use, but I would use the same lead for all of the speakers.

 

So the Ref. series only have a high pass filter on the tweeter and thats it???

 

its has the external crossover so is there any need for this capacitor?

 

I would think a company such as Infinity would cover this in the owner's manual. Maybe they include this in case the user wants to use the tweeter on its own. If the component set has a separate crossover module, then you shouldn't need to use the inline capacitor.
