Daniel Francis Sheppard Posted March 27, 2016 Report Share Posted March 27, 2016 I was running subs today at about 1/2 volume of max . My system has been tuned with the dd1. No eq or bass boost everything set flat and 0. Today with volume lower then usual... I heard a noise that was a loud buzz sound and then it sounded like a slinky hitting a wall. I immediately pulled over and the sub was still playing just not as loud. I pushed on the front and I can feel the coil rubbing. The sub was not hot or overheating. I had an old JL audio blow before but it usually would be super hot and have dust/smoke coming out the holes. This sub is a newer w3v3 that I have had for less then a year and purchased as a pair. The other is completely fine. When I put the multimeter on it, it read open but when I move it, it jumps around in Ohms alot. Could someone enlighten me or what may of happen? Is it blown or did the suspension go on it?? I plan to get it repaired by JL because they charged a flat rate repair of $150 on w3v3s. Both tinsel leads look perfectly fine and the spyder is untouched. From within the cone I can feel the whole shape of the coil pressing forward.

Hence the word "nominal" . If you get a reading at all it probably isnt a blown coil.

Daniel Francis Sheppard Posted March 27, 2016 Author Report Share Posted March 27, 2016 I have taken it out of box already and listed everything that is visible to me in post. I feels as though what holds the coils down by the magnet has broken and is letting the coil move freely up to the cone. I have never had an issue like this before especially so early on. All my JL audios typically last about 5 years before issues. I feel like this sub may have had some type of factory imperfection . Link to comment Share on other sites More sharing options...
Skullz Posted March 27, 2016 Report Share Posted March 27, 2016 Subs either work or they do not, there is no in between. When something feels funky then most likely it has an issue and either needs a recone or replacement, just because it is a JL Audio does not mean it can't be fucked, your just assured a certain amount of quality with their products, you'll either need to repair or replace it. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

Daniel Francis Sheppard Posted March 27, 2016 Author Report Share Posted March 27, 2016 Can you see the actual coil through any vents below the spider pack? Nope completey sealed all the way around. Like I said it looks as those its brand new minus the rubbing. When I push down on spider on left nothing but on right there is rubbing , which is the same rubbing occurring on top by cone. I guess what I was trying to figure out is the damage on it my fault or something malfunctioning? Link to comment Share on other sites More sharing options...

Daniel Francis Sheppard Posted March 27, 2016 Author Report Share Posted March 27, 2016 The way it was setup originally was to protect it from this result... which is why I dont see it going bad. filters set, flat everything, tuned on dd1, running 2 w3v3 w/ HD 700/1-- so subs werent maxed out of power. Gain was set a quarter turn below top spot. Link to comment Share on other sites More sharing options...
