Today it is 88°F out and the humidity is at 66%. alright so i was driving back from lunch and im playing lil waynes lollipop when all of a sudden my sub cuts out. Im thinking i mutsve pushed something to stop it from playing or there was a loose ground. so i put my stereo on standy to turn off my sub and keep driving. 1 minute l8r i smell something smoking or burning and im thinking its something from outside coming into the car. Well about 30 seconds later the smell has become more potent and so i turn around to look at the sub and my whole car is filled with smoke and i can see it coming out of the port of the enclosure. I pull over and air out the car and i touch the dustcap of the sub, and it was extremely hot. The heat was so hot it melted a portion of the dustcap. so i drive back to my house unscrew the sub from the enclosure and examine the sub. 2 voice coils blew and you can see in the pics that it started to melt. Alright I have a couple questions.

1.Why did my sub blow up

2.Should I purchase a new recone kit

3. Should I upgrade to an RE MX or Fi BL instead?

Here they are

You fucked her up pretty good!

Where you @ in MI? Want to sell me the motor?

One tinsel snapped, touched the other, shorted out and the arc created was the heat that caused the cone to melt.

When I looked at the first pic I thought that was an odd place to have excessive heat, as that was no where near the coil. But yeah, it was a dead short from the tinsels touching. Check your amplifier, it might not be a happy camper either after seeing a dead short.

Oh, and you originally 'blew' the sub with over excursion, which caused the tinsel to break.

Yep... Audioholic nailed it... my exact first thoughts when I saw it.

Another victim of the zomg it will be teh underpower!!!111 mentality that just leads to lots broken sh!t.

ok stupid question. the tinsel is the rouch fabric thing glued down with th wavy pattern right? and the spider is the actual metal pole/supports on the basket right? So what should i do? purchase a recone kit OR buy a sub with a higher thermal handling like the RE MX or Fi BL? Would could have cause the sub to blow though? The heat and humidity in the air? Too much power sent to the sub? I was running it off a Cadence TXA-1000D. I bought this sub from ebay for 140 about 2-3 months ago and the guy b4 me had it for about 5-6 months.

The tinsels are the wires going from the terminals to the voice coil -- one of which is clearly snapped. You ran too much power to the sub, which caused the driver exceed it's mechanical limits, and your tinsel lead snapped. When it snapped, it touched the other lead and created a short.
Obviously an SX at full excursion isn't going to cut it for you, so you should consider either adding a second one, or stepping up to something with more output capabilities (and the increased power to go with it).

Edit... I'm guessing maybe this was a ported box, tuned fairly high, and the music was playing well below tuning (in which case tuning lower may keep this from happening again).

tinsel is metal wire

basket it metal bars that connect the motor, what actually mounts the sub

spider is wavy fabric thing

You have it backwards. The spider is the wavy cloth material. It has a spring woven into it, as a suspension piece. The tinsels as the wires leading from the speaker wire connector, to the coil through the cone.

my enclosure is 2.197c^3 tuned at 33hz. The SX's displacement is .16c^3. If i purchase a RE MX the displacement will be .19c^3. This only affects the tuning of the enclosure by .05hz so i think i will be going with the RE MX. Thanks for answering my questions.

Sell me the motor then..

 

[Oinkypig 10+ year member]

gonna keep the motor and probably get a recone. then ill stick it in my 1959 cadlillac with a Hifonics Brutus BXi-1208D amp. How much were you thinking on spending for the motor?

did you have that hifonics 1208D hooked up to it?
