Magic Bag Of Sounds
i left my monitors on overnight, and with daylight savings time making my 7 hours of sleep turn into 6 and people calling my cell phone (therefore making the speakers buzz), i deliriously got up and attempted to turn them off in the dark. the result was a crushed in cone on the 5" speaker (m audio sp5bs). i don't notice any difference in sound, but they look like hell. i read on here earlier that you could just use a vacuum cleaner to pop it back out, but that didn't do anything unfortunately.
anybody know any remedies or know how much this ruins the frequency response?
 
I've popped the cones back out on speakers by using a piece of scotch tape and a piece of string. tape one end of the string to the cone, put your finger over it and press lightly while pulling the other end of the string. Pull with just enough force on the string to counter the force of holding the string/tape on the cone, which isn't much in the first place. Just be careful.
 
scotch tape definitely isn't sticking to these
 
By crushed cone, I assume you mean the round part that sticks out in the middle? I wouldn't worry too much about it. It's a dust cap, it's purpose is to keep dust out of the voice coil gap in the magnet.
 
I picked up a pair of SP-5Bs with the dust caps poked in. Vacuum cleaner worked well, though there is a bit of dimpling on the caps still. Used the "wand" on a big upright vac and placed it against the cap (not just near it). Might be worth trying again, as it's an easy fix.

If that doesn't work, or you don't care for the dimples, you can get replacement dust caps at http://www.partsexpress.com along with the cement to glue them on with. Removing the old caps might be tricky though... never tried it myself.

Another option might be to unscrew the driver and look for a vent in the center of the magnet on the backside. Many speakers have this, and it may allow you to place a pencil through the hole (eraser side of course!) and push the cap back out.

Finally, you could try a straightened paper clip or pin with the end bent into a little "L" shape. Push through the cap and use to pull it back out-- like fixing a dent on a car. A small dab of clear nail polish or paint can then seal the hole.

Good luck!
 
I will solve your problem little one, but only because I am feeling frisky.

Remove speaker.

Blow into back of said speaker. (you know, the little vent in the back.)

Replace said speaker.

Enjoy.


Seriously, my Behringer 2031A's are as good as new. Just take off the speaker and blow (relatively hard) into the vent on the back side of the speaker. I didn't believe it either, but I had nothing to lose. It worked.

Blowing your speaker.?.............................................. do it behind closed doors.
 
i was hoping "replace said speaker" was gonna be a "those monitors are crap!" comment
 
I used packaging tape. I got a pencil and used the eraser end and put the tape on and pressed it with the pencil. Then just pulled it out. The packaging tape was sticky enough and it didn’t leave a residue. My next thing if that didn’t work would be to pry it out with a needle but I don’t know how advisable that is.

Oh yea. My 1 year old pushed one in and the 7 month old that my wife was baby sitting pushed the other one in. man I was steaming. But I couldn’t stay mad at my baby. Besides it was my fault because I had them on the floor and I hadn’t cleaned out the spare bed room where they were going to go. At least they didn’t punch in the whole speaker.
 
The dust cover doesn't really do anything sonicly. It just keeps the dust out of the voice coil. Having it smashed in is just a cosmetic problem, it doesn't hurt anything.
 
thats good, i'm not sure how i never knew that it was just a dust cover. is it the same for tweeters?
 
If it is a tweeter that looks like a little speaker, yes, but I haven't seen one of those since the 80's.

If it is a dome tweeter, that is the speaker.
 
i just realized my shop vac was broken, used another vacuum and it popped back as good as new
 
As long as they aren't paper based, which I don't believe those are, then just suck them out with your mouth. lol

Seriously, that's what I've done...put my mouth right on there and suck. That way you control the suckage, which you can't do with a vacuum. Worked like a charm for me.

I think there is something in the forum rules that requires you to post a picture of that. :p
