Sundown E8 blown?

[Alex JB 10+ year member]

OK, so I'm quite sure that I just blew up the single E8 I was trying out ready for my double 8 set up //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Just confirn for me these tell tale signs.

very small extension, sound is ok.

medium extension, sounds like cone is rubbing on something ( I checked it isn't)

larger extension, no where near as load as it used to be, lots os scratching/rubbing noise as the cone moves.

Put a fork in it.

How much power were you running and what box? I was thinking about a couple of these for my truck.

Put a fork in it.

It's done. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Are these fixable?

Is it worth fixing, or just move on?

I was planning on getting 2 in a box, I chose this sub because it only needs 0.5 cu ft ported and 0.5 each net is all I can get.

It's either 2 more or e RE 8's

2 more

how much power to each?

how much power to each? what amp?

What kind of power did you have on it and what enclosure?

What kind of power did you have on it and what enclosure?

I'm running a 4 channel with 2 rear channels bridged to 1.

It says 1000w on it, I just got it from SCtattooer so I don't know it too well yet.

So who knows, maybe 150 - 200W RMS at 4Ohm?

I think SCtattooer said 225 at 2Ohm. bridged.

So I didn't think I was going to over cook it, especially with the gain only 1/2 way and the filter at about 90Hz.

I made my own box, it's 0.6cu ft net with a 4" x 2" slot port that calculates as 32 Hz but it seems to peak at 40Hz.

Did I do something wrong? //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I am not familiar with the specs on the subs or the amp, but from what you listed i dont see the problem. I've run JL 8s in similiar set-ups. I would PM jacob, SN Sundownz, and talk with him. Hes the most knowledgeable for this .

Where did you get the E8s ?

 

[Alex JB 10+ year member]

Bought it here from Basic1908.

Think it was relatively unused.

Check to see if the spider is glued down still - you will break the spider loose before blowing the coil thermally.

Also try moving your leads around if it is the old one without tied down leads - you may have developed a little lead slap.

If all else fails "woofercooker" can re-cone it for you pretty inexpensively.

Thanks for the points to check.

If the spider is loose (to be honest I don't know what this means! //content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gif ) what can I do about it?

Is it a re-cone form Woofercooker? Can I fit a re-cone kit to this myself without special tools?

Last night I paid Woofercooker for another E8 to make up the pair for my new box!

This morning I had to asked him to hold the shipping for a day or two so I can check out what I need to do.

If you have not re-coned before I would be hesitant to suggest you do it yourself. The E8 gap is pretty tight and not tolerant to a mistake in alignment.

The spider is the wavy cloth thing under the cone - make sure it is glued to the frame still. The E8 voice coil is very difficult to blow so chances are something else happened and not a blown coil (see video at bottom).

You can send it to Mike (woofercooker) and he can do the whole job for you - would likely be cheaper than a new one even with shipping.
