Posting in correct section - Spider came loose

Ok,
The spider for my new subwoofer came loose. Not sure how, as I have the gains at minimum, and have not cranked her too loud yet. Either way, I was informed to buy some Crazy Glue Gel and try to reattach it.
The spider came loose from the basket, so I used some Crazy Glue today to put it back down.

I will load the drivers in the box later today or tomorrow and test her out. What could have caused this? As I said in the other post my HU has 2V Preouts, and I had the gain all the way down. I cannot see too much power going to the subs. Also, only one of them did this. I built the box myself, I can test to see if it is not fully sealed. Is this something that could cause this? Any thoughts guys?

without a doubt you had a defective sub.... what brand/model is it ??


At anyrate your fix should work... I would have used epoxy, but cyanoacrylate gel is the next best thing........

Bought it off ebay, I now see why he sold it so cheap.

Hopefully this should fix it, if it comes loose again I will use epoxy next time. If it works with the glue, it was still a good deal. If not, I will be pissed.

The subwoofer was definately new. Hey may have tested it out and heard the flapping sound and decided to pawn it off on someone else. With luck I will find out tonight.

Appreciate the response.

Looks like it is fixed. Loaded and sounds fine.

Question. My sealed box was built far too big. Used a wrong value in the calculator. Should have built it to about .71 CU FT/chamber, built about 1.5 CU FT instead.

Should I rebuild? What will this cause? Bigger better? Bad?

Oversized box = Overexcursion (even at low power) = Ripped or detached spiders.

Maybe the sub was fine when you bought it

yeup.. mechanical power handeling may be decreased... and accuracy will also be affected...

on the other hand I might prefer having the lower extension, improved transient response, and lower power compression....

but it all depends on the sub....

at any rate many ppl aim for a Q of .707 but even .5 is fine for me when it comes to subbass.... on the otherhand if you are into sq you may reason to go >1

post t/s if you need more help....

also the spider should rip before it comes unglued on any decent sub IMO...... if thats how rf builds subs I don't think I'd want one....

No rips and it was only one sub.

I will get a proper sized box before I do anything with the subs. I would prefer a tighter response anyways.
