Newbie Question: Dent in dome
Let me start by saying I'm a newbie with very little knowledge of speakers.
I recently purchased a pair of RTA 11t and one of the speakers below the tweeter has a dent in the dome at the center of the speaker. I was wondering if this would impact the sound. I have tried comparing it to the other speaker and it sounds ok some times and degraded other times.
So I was hoping to get some expert opinions on whether or not this should impact the sound.

Use some invisible Scotch tape, apply gently to the indentation and slowly pull the dent out. It may take serveral tries. Others here will also chime in about the methods they've used to take care of this problem

+1, ive pulled out dents in tweeters with tape. I used duct tape and it worked. but i would think scotch tape might be better.TV- Insignia 46'' LED,1080p,120hz

thanks. I tried to use the tape method with no luck. Here are some pictures.

On closer inspection it appears someone may have tried to use a needle to poke a hole in try to pull out the dent. Is there anything unsafe about this?
I just don't want to do anything that would inadvertantly damage the sound. -
Try using one of the extensions from a vacuum cleaner. It'll need to be one with just a simple round tip(no brushes or anything like that).
Put the tip of the nozzle against the dome and turn it on. The vacuum should make the dustcap pop back out. There will likely still be some minor creases in it, but it'll be much better than it is now.

I too have used the vac method one other is to use a cardboard tube from paper towels and use the suction from your mouth to do the same. i always work up to the vac trying the paper towel tube first. all the rest you have been told here works also. A small pin to pull out the dent also most of the time has no effect on the sound or so little you'd never notice. -

Good suggestion, I've never even thought of using a paper towel tube.

I've had great luck pulling out dented dust caps with a shop vac. Good as new.

A shop vac? Damn...that's overkill.
I would definitely try a standard home vacuum before trying a shop vac.
A shop vac puts out a lot more suck than a normal vacuum does. I'd be worried about ripping the cone right off the spider with a shop vac. We're just trying to pull out a dented dust cap, not pick the whole speaker up with a vacuum!!The nirvana inducer-

LOL Curt, like the old saying goes, anything worth doing is worth over doing right? In all seriousness though, the shop vac may be a bit too much.

I put a dent in one of my Monitor 60 tweeters when I was switching a woofer out and I managed to massage around the dent until it popped out. I was gentle so no damage occured. Yours however looks a lot more dented in than mine was.

Yeah, kind of like building a lawn mower with a big block Chevy to mow a 10x15 foot strip of lawn...lol
Is it cool? Well...yes, in it's own **** way. Is it necessary? Not in the slightest bit. At all.:p
This reminds me of the VCR I modded some years back. It stopped outputting audio and video, but the rewind/fastforward functions kept working. Out of boredom one day, I decided to tinker. I modded this thing so that it would rewind an entire 2-3 hour movie in like 20 seconds flat. It made noises that you wouldn't think could come from a VCR. Only like 1 out of every 10 tapes actually survived a trip through the Rewindinator...lol...but it was an interesting experiment either way.
In case anyones wondering...the mods were bigger gears, and the bypassing of the regulator in front of the motor that turned the spindles.Underworld54 wrote: »I put a dent in one of my Monitor 60 tweeters when I was switching a woofer out and I managed to massage around the dent until it popped out.

Just for the record, the vacuum method probably shouldn't really be used on tweeters. Tweeters are a little more sensitive to being dented than a woofers dustcap though. The tweeters dome is the entire radiating surface though. The only real fix for a dented tweeter, is a new tweeter(generally speaking of course). Good to hear you managed to get it resolved in your case though.Knucklehead wrote: »LMAO....my shop vac would suck the driver right out of the cabinet...
That's what I'm saying. It would suck the MW out to it's full excursion, and probably rip the cone right off of the surround. Granted I've got a pretty powerful shop vac...but still.
Definitely try a household vacuum cleaner first.The nirvana inducer-

I just use the house vacuum. 1 time I had to use a bent needle to pull it up a little then used the vacuum, worked like a champ.

I wasn't able to get my Dyson to pull out the dust cap on a MW6502 that had a dented cone. My 5hp shop vac did a good job.
The Dyson works great on cardboard dust caps.
That Polk dustcap is vented which requires more air flow to create a strong enough suction to pop it out.
My shop vac has a hole that can be adjusted to create a leak and lower the suction power it has which makes it easier to control the peak power.
Don't try a vacuum on a tweeter, it will pull the dome right off. Scotch tape is you best bet for tweeters."Make a man a fire and he'll be warm for a day. Light
