misterbassman Posted August 18, 2004 Share Posted August 18, 2004 Hey everyone, I have just bought some second hand Turbosound TL1500's. I have just come to fire them up and one of them doesnt produce bass. I opened it up to check the wiring/crossover and everything was ok. So I tried pushing the driver and it was rock solid, this makes me think that the voice coil is dead. I think Im right in saying tho that generally if the voice coil breaks (melts) a short is created, so I put an ohm meter across the terminals and it read at 6 ohms. Im just a bit confused now as to what is wrong, but it does look like I will be needing a new driver Link to comment Share on other sites More sharing options...
Andrew C Posted August 18, 2004 Share Posted August 18, 2004 I have seen the lacquer that holds the coil winding together melt. This could cause the sticking that you are experiencing.... and yes, I'm afraid it sounds like a new driver. Link to comment Share on other sites More sharing options...
Lamplighter Posted August 18, 2004 Share Posted August 18, 2004 Dan Try a 1.5 battery (C or D cell) directly across the speaker terminals. You should see the cone move otherwise it needs a recone or replacing. Brian Link to comment Share on other sites More sharing options...
