Blown Speaker? Weird Fuzz from one speaker
« on: April 21, 2016, 12:38:22 PM »
  Finally got my amp and went to test out the rig last night.  Immediately noticed fuzz/distortion from top left speaker.  I do notice the speaker has been replaced and does not match the other 7 speakers, so it was most likely replaced at some point.  Funny thing is I did not hear this distortion when the seller demo'd the cabs for me w/ his Sunn amp.  I am running a wt550 used from GC just came in mail.  Set level indicator not showing up, overload warning above it does show.  Any thoughts / cost of repair?

Which cab are you talking about?
Take the dish off in the back and have a look inside.
Maybe a cable is touching the cone.

Without tools, you can lay the cab on its side, back (propped up with something to allow space for the speaker cable) and upside down to see if the buzz stops.  If it stops, it was a wire touching the cone and you can later get inside and shorten it or tie it off with a cable tie.  I'd try that first, then proceed from there.  One non-Eden replacement speaker is a bad idea so you're going to want to correct that when you get the chance.  Good luck, Bob

Excellent field advice Mr. Bob.  Where is the best source for Eden 10" speaker replacement?  I was happy w/ your source for speakons.  Made 2 cables for less than price of one cable!  I've noticed the original speakers look like hemp cones w/ hemp center.  my problem speaker is made of some plastic and has grooves/ridges in the cone surface.  I want my rig back to original running order.

I think Eden did (and maybe still does) use a little hemp in the speaker cones.  Eden OEM speakers are only available by order through any authorized Eden dealer and they're costly, but you need to get that junky replacement out of the cab.  Too bad the seller didn't save the original so you could have it reconed at a reduced cost.  You can also check the for sale forum for any spares members might have offered for sale in the past and e-mail the member to see if it's still available.  That's all I've got.  Peace, Bob

  Very strange things happening.  So I took a look at what the situation is.  Took the speakers out and much to my surprise this "replacement" speaker is stamped eden on the magnet (EC 1060 XL 33/98) 4 ohm.  No sticker on back, just generic ink stamp with that information.
  I take the "original" looking (i can tell from eden photos how they look) speaker out next to the "replacement", fuzz speaker.  BUT THIS SPEAKER IS 8 OHM (EC 1060 XL), 8 ohm.  This speaker has a black/white sticker from factory w/ information on it, etc.  ...made in USA Minnesota.
  So what the hell is going on?  Will a 4 ohm speaker cause this fuzz?  I am thinking I may have been robbed at my studio by someone knows I have this cabinet??!!  I cannot say for sure, but something is fishy to say the least.

My cabinets are D410xlt/ 8 ohm

I guess that speaker is reconned and the information on the back is not correct.

It would be good to check that speaker with a multimeter to make sure it's been reconed to 8 ohms like Armin thinks.  Any cheap multimeter will do and the DC resistance across the positive and negative terminals should be around 6 ohms for an 8-ohm speaker (the resistance is always less than the speaker's impedance, around 3/4).  Good luck, Bob

  Most certainly will test the resistance tonight.  In regard to that buzz, I think speaker may be damaged.  Didn't seem like wires were touching the cone.  When I lightly press on the cone, I can hear and feel ever slightly a soft pop.  As if you made a plosive sound with a consonant "b" or the pop you hear when adjusting pressure in your ear pop.  No crunch, just something sticking very slightly on top of push.

I'd still test the resistance--if that was a 4-ohm speaker, it would have drawn more current than the others, probably leading to the failure.  Make sure it gets reconed to 8 ohms.  You'll find some places to get speakers reconed in this thread: http://www.edenampsforum.com/index.php/topic,19309.0.html.

Good speaker measured 4.5 Ohm.  Bad speaker 7.5 Ohm.  Here is a sweep test I did with my neighbor, Neil.
