can someone tell me what I'm doing wrong?

[dragon123443 3]

Since October I have blown 2 subs using the same enclosure and amp. I have the right electrical to back it all up. Originally the sub was a 10 inch xcon which I popped mid November then sent it to SPLaudio for a recone, received it back mid December and now I popped it again. it is in a 1.4 cube box tuned to 32hz. All gains set right and all bass boosters on my stereo are at 0.. any help is appreciated. Thank you.

Where is you subsonic filter set?

Where is you subsonic filter set?

I have a fosgate amp. It has no subsonic filter .. just an infrasonic filter, if that helps? I have it set to "on"

[jcarter1885 995]

What kinda amp is it (model number)? What does your electrical look like?

It is a Rockford fosgate punch p1000x1bd

I have a 230 amp alternator from singer, big 3 upgrade using 0 gauge and an xs power D2400 under the hood.

I bet you keep playing below tuning and pop the leads, you need an adjustable subsonic/infrasonic filter.

I don't play anything lower than 34 hertz. I don't like the way anything lower sounds on my setup. At the time I smelt my sub burning up I was playing Hideho tuned to 37hz

And you know this how?

If the sub was actually burning, the gain is not set correctly. Was the smell happening when the sub was brand new out of the box?

What did the recone company say the cause of failure was?

[jcarter1885 995]

What do you mean by you popped the sub? What keeps getting damaged?

[dragon123443 3]

Good question..

It wouldnt smell, at least not like it did today

It barely happened, haven't had a chance to talk to the dude yet.

The first time, the sub just sounded really bad. It would make popping noises on every note. Until one day it just started to smell really bad and stopped playing all together. Today I got that same smell and then after that it just started playing bad it doesn't sound the same now.

according to decafs titles.. unless they are off by the frequencies they claim

Too much power. The only way to burn a sub up.

1000 w on a Xcon ? It's not a lot of power for such a sub.

Gain was set to high, maybe. How did you set the gain ?

 

BTW 1.4 ft3 at 32 Hz ? I bet that port is loooong  ! Or the tune is way higher.

Thanks bro. I think your right on the money

Then you have been clipping the hell out of it, 1000w will not blow an Xcon

I set it up according to fosgate instructions for the c.l.e.a.n. circuitry.

I actually didn't build the box. That's what I was told the airspace and tuning was. It has a 3 inch aeroport

Did you hear the coil bottom out on the backplate? This would easily happen without the subsonic filter and cause the sub to sound like shit until the coil gets destroyed completely.

Not a prob. I normally am.

I am still a noob. I wouldn't doubt it..

Not lately but I do now what your talking about.

[Quentin Jarrell 671]

A clipped signal creates more power over a given period. This is the only thing that will kill a sub. The coil is just a wound up wire it doesn't care what type of power it recieved as long as it does not exceed it's thermal rating it won't break.

The only other reason for failure would be the tensil leads breaking which should not be an issue as the parts should work well past the mechanical clearance of the edge.

Or the coil is bottoming out and the coil is shorting out on the back plate. But you should be able to hear that.

I think clipping is the answer. I need to do my research and learn how to setup my gains better. I do feel the sub get a really warm at time. I need to take it out and check the tinsel leads. And make sure its still OK.. also I've noticed my box leaks air around the speaker, might that have something to do with it?

Yes, it can have detrimental effects on the sub, the way it performs and the power it can handle.  

 

Give us the exact dimensions of the enclosure and the length of the port that's being used and we can verify with better certainty that your enclosure is indeed 1.4cuft and that the port is tuned to 32hz.  The XCON's are NOT easy subs to tear up and you're probably trying to get WAY more out of the sub than it can deliver.  I have a 10" XCON on an SAZ-1500 and it never gets warm, never smells and should last a very long time.  On that Rockford it should last an eternity with only 1kw feeding it so I would imagine it's a combination of things, air leaks, questionable enclosure specifications, and clipping that has lead to the demise of the sub, twice.

That's what I was thinking.. its a bit hard giving dimensions cause the box is not rectangular like normal boxes.
