What's the speaker output doing going to the field coil? Here we are only looking at “abuse” causes of failures and not factory defective speakers. The wire may be of round section or sometimes edge wound strip wire is used. For fun, I took the tweeter apart after confirming that it is "open" between terminals. Step 10: Glue the Foam Edge to the Frame. Place the speaker cone and spider in their proper positions after that. The most common type of speaker coil is the single voice coil. It kinda peels up on Its own once you get it going. Follow the video and you can rep Under normal operation, a speaker coil moves just a fraction of an inch. The process begins when your amplifier sends an electrical signal to the speaker’s voice coil. What's new. The problem always comes from the power that the speaker produces. No products in the cart. A spider is another component found in subwoofers. Speakers are essentially large coils of wire, and when they "blow", it's generally that the coil is taking too much current and isn't being cooled enough, and is damaged. Symptoms of a blown subwoofer voice coil may include distorted sound, loss of volume, and reduced functionality. The voice coil is a coil of wire that is wrapped around the magnet. gl/bjtt How to reconnect and repair a speaker or subwoofe speaker. It’s a special “voice coil” speaker. Inspect the voice-coil gap.
