View Full Version : Either Tinsel Slap, or coil rub... not sure.

HAI GUYZ!
My right speaker occasionally makes this sound that kind of sounds like there's something on the cone with the driver faced up, and it's just rattling across the cone. It only happens sometimes... I'm thinking it's tinsel slap (I have no idea what it sounds like, but it does kind of sound like something is hitting the cone), or coil rub. (Don't know what that sounds like either.)


Any help on how to tell? I'm probably gunna pop open the door this weekend and see what the deal is. Maybe put a piece of felt around the tinsels. (Or are you supposed to just put the felt on the cone above the tinsels?)

Coil rub you would hear at low volume and will sound like scratching. Tinsel slap usually leaves evidence on the under side of the cone. A loose dustcap will have a platic popping/fapping sound.

sorry to thread hijack, but what is the dustcap and can it be fixed?

Alright. I'll check. Thanks. Will a piece of felt lower the sound?
And it's only at medium/high volumes. It doens't happen at lows... and only during some parts where there's mid-bass.

The dustcap is the center part of the driver. For subs, they're normally big, for small mid-range drivers, they're small and circular. They're just supposed to cover the coil.
If it came off / came loose, I know you can use CA Glue to put it back on. People who recone full drivers use CA Glue to put on the dust cap. Not sure where to get it, what brand, etc. I just know the name of it.

Coil rub doesn't mean the coil is bad. Just means that somehow the coil isn't centered anymore, or became disformed.

I know what all of these things are, just not what they sound like. Heh.

I hate you sometimes-- actually, I hate you often.

You still need that enclosure designed? I feel like an *** for saying I'd do it, then completely forgetting about it. :x

Yeah. I guess I have to. I was kinda hoping to trouble shoot it with out taking my door off-- I just hate taking my **** doors off.
P.S. I kinda miss you, Rash. (No homo).

Yepp. The Hertz. I've been wangin' on 'em for over a year now, and at one point for about 5 months the volume would be at nearly full tilt for 30+ minutes on my way to / from school. (Traffic's a *****.)
They're still the best speakers I've ever had.

Ouch. That hurts.

The Hertz are ******, man. How can you say otherwise? They sound like God's balls slapping up against his legs. (Assuming that all things emitting from God are good.)

In like "You're the last living person" situation, or like, "If you were closer to me" situation?
Either way, I'd have to agree. =|

Oh, lmao. My bad. Yeah, running a pair of Hertz ESK165's. Their entry level ones. But they still rock face.

If it is, its over excursion hitting the back plate.

if the VC is hitting the backplate, you'll have coil rub soon enough. cross over higher.

I just took out the driver... and when I only pushed on one side, I heard some rubbing... but when I pressed on 4 sides, rather than 1, no rubbing... but I did hear scratching toward the maximum excursion, but I'm assuming that's normal. I played it for 10 minutes, on high volumes on songs that have a lot of mid-bass, and I didn't hear anything. I did notice that my baffle is a POS and that it's not completely sealing off... so, looks like I need to borrow a jigsaw ASAP.

could it have been something rattling that you were hearing? like in your door? Before I deadened, on some hard midbass notes, panels would resonate bad enough to sound like distortion coming from the speakers
