Late pl50 driver pic, this does not look like a balanced armature driver

Here is the membrane, it's a dynamic driver

I guess you've got yourself a chinese fake.
Did it sound like a tin-can phone?

with sony silicon tips they sounded good, with clean and very forward mids and tight bass, treble is rolled off, one of the drivers started to buzz and I look inside

Did you typo Pl50 instead of Pl30? 

 

 

[FastAndClean]

No, it's pl50

I've heard a lot of good things about these, but god damn, I hate the way they look. And that's coming from a guy that loves his Stanton Dynaphase 75s.

I am changing drivers on some California Headphone Company Silverados. Converting 32 ohm to 250 ohm for use with a Bottlehead Crack. Also converting them from closed to semi open. The replacement I am using  fits with very little modification.

What a nightmare of a change this Head-Fi migration has been.
Anyway, the absolutely horrendous Pioneer SE-205. Working on a new Baffle to get slightly more out of them.

What's horrendous about the SE205? I think the SE505 is pretty nice sounding, is it far off?

For a paper-cone of this vintage, I agree with you. It could have been a whole lot worse when you compare it to others from the same era.

It has to do more with the chamber than the Drivers, I was having a hard time correcting it because of the cancellations taking place. Drivers should perform a little better on a better Baffle, IMO.

AKG K500.
Audible and unpredictable Non-Linearities due to the dusty diaphragms.
Best way to clean is using tape and then finishing it off with a very mild wash using Isopropyl Alcohol. Works beautifully.

Restoring a pair of Realistic Pro60 (Koss HV-X)
They were seriously messed up. I got them on the cheap though, so i'm not mad. The biggest problem was that the original owner must have dealt with the original pads deteriorating by gluing on some makeshift foam... They must have lost one of the original baffle extensions in the transaction, 'cause I only received one. The DIY loser that did the work actually gobbed glue directly onto the baffle plate, gluing the driver to it's own housing. Needless to say when I got the device and plugged it in, I was quite flabbergasted by the sound in the busted side. After spending quite a few hours pulling little bits of glue and foam up, I was able to take the cans apart (these things are a bitch to open up) and the inside was really gross. The foam had dry rotted and turned to powder at the lightest touch, but worse than that there were little insect larvae carcasses woven into the foam and strewn across the drivers. Yuck. I did my best to sterilize and clean all of the parts. I was also able to separate the driver from the glue with a bit of patience and orange based cleaner. I finished off by replacing the foam sheets with rough non-woven material similar to the scrubbing side of a sponge.
