    This isnt a modification mistake or really my mistake but -

    At my job we carry 1/4 speaker cables (live sound) and the company, not to be named had put so much solder on the connections that they + and - were actually touching...

    I think it goes without saying that did not end well and scared the crap out of me...

    Pittdog2, have you ever re-glued surrounds that were still in pretty good shape but not rotted? I have some AR's that separated from the woofer cone (not all around) but the surround is not rotted. Is it worth it to try to just re-glue, or is it preferable to simply start over and re-surround?

    I have not but it's worth a try you really have nothing to lose. Most of the glue used looks like Elmer's but it's not. I would try just a little contact cement on both sides. Most know contact cement only sticks well to other contact cement so that is why you need to put on both. Really i wonder why it came loose? that usually doesn't happen.

    I was about 13 or 14 and my older brother asked me to hook-up his new equalizer for him. I read the directions twice which didn't make sense and then hooked it up according to the directions. When I turned on the system, the most awful extremely loud snap, crackle and pop came out of the speakers. My brother face turned tomato red and I thought he was going to kill me. I then hooked it up the way I thought it should be connected and whala perfect sound. Since then my brother always calls me on any tech. advice.

    Go to Wal Mart and get some Kraft glue. Elmer's makes their own variation of this and it works well.
    I had a pair of Realistic T-100 speakers that did the very same thing. Just glue them back down with Elmer's Kraft glue and they will be fine.

    Don't you know. They have never blown up or wrecked anything. That's how they are so knowledgeable, by never learning anything. ....red plugs for example. I was learning the remote on my TGP3 and hit the PL2 button and cooked my center channel tweet. Like sparks and everything lol. iI happens. I wonder where that smoking driver pic is? That was a good one.

    I remember someone posting a pic here of a fried tweeter - and man, it really was fried! Was that you?

    I rebuilt Xovers on a pair of speakers once, my first rebuild. Everything went great and then I connected them. They just didn't sound right, kind of like a really good am radio :redface:

    I called up the guy I bought the caps and resistors from and described what I was hearing, but his suggestions on fixing it didn't seem correct. I stared at the schematics for a long time and realized I had soldered a resistor in the wrong spot. Fixed it and, Voila! Beautiful sound.

    Didn't mess up anything permanently, but those speakers sounded awful until the Xovers were fixed.

    Not particularly relevant as it didn't happen during a mod, but entertaining nonetheless:

    Ah yeah, that was a fun weekend.....
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Funniest part of that is that the speaker went POP and started smoking, and my first reaction was to take a picture to post up here!

    I would have been too freaked out to react that quickly! :lol:

    Also can't speak to any disastrous mod scenarios, but I do have an SDA mod sob story:

    I picked up a pair of stock SDA 1A's that were sitting in my (now ex-) girlfriend's mom's attic for about 10 years. My first 'real' set of speakers, I was pretty excited, and promptly went to google to figure out what they were. I was consequently directed here and my wallet hasn't been as heavy since. Assured by the gf that they were indeed my speakers, I went on to add Larry's rings, dynamat, armaflex, disconnect the SDA tweeter, and predictably they sounded remarkably better.

    I had been saving up for a crossover upgrade when we broke up and she asked for them back. That's when this story takes a turn toward the tragic. These speakers that got me into audio, that I babied and put a number of dollars into, were taken from me a few weeks back despite my pleads and offers of money. Worst of all is the fact that in a household of four women, there's no way they are in use, and will likely be either in an attic somewhere or brought to goodwill for a tiny tax rebate...what a waste. :cry:

    Horrific indeed. :eek:

    I'm just waiting for her to give me a call for advice hooking them up, at which point I'll inquire nspindel about exactly how I can start a fire in their living room... :twisted:

    OK, let's be honest, I would never do that to a beautiful pair of Polk speakers...
