April 21, 200818 yr I'll double check later to see what I can find, however dust still wouldn't cause the driver assembly to sound like it's rattling about in it's housing And no, these drivers are kept well away from the woodchipper
April 21, 200818 yr I'll double check later to see what I can find, however dust still wouldn't cause the driver assembly to sound like it's rattling about in it's housing And no, these drivers are kept well away from the woodchipper Odds are you will never see it. You can try to view the diaphragm at an angle next to a strong light and watch for something that stands out in the reflection. The driver assembly is the housing as the stators are attached directly to the plastic shell and the only other two bits are the small metal bit that connects the bias to the diaphragm and the diaphragm itself with the attached metal rings. With the housing shut tight there is nothing to rattle inside but the diaphragm can to some crazy shit when there is an intermittent short to one of the stators.
April 22, 200818 yr I have a similar problem with my SR-5 pro But the thing is I've already vacuum cleaned the drivers twice, and its a continuous static noise in my case. Balance et al are perfect, at the moment at least but the drivers were never in great condition in the first place :/ Anyway, I think the nickel film that connects to the diaphragm may need replacing. I'm thinking of using this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140222166435

You risk tearing the diaphragm as mylar has great tensile strength but tears like a very thin sheet of paper. The crackling comes from small arcs between the diaphragm and stator so the charge ring isn't really part of the problem but it's worth a shot to replace it with some wire and see what happens. I would look for some large piece of dust that is one of those 15% negatively charged and is stuck in one of the stators.
April 22, 200818 yr Won't a dust particle get zapped and turned to ash? Just like an electrostatic air filter?
April 22, 200818 yr Won't a dust particle get zapped and turned to ash? Just like an electrostatic air filter? The bias isn't high enough nor the charge strong enough to do anything like that. Even electrostatic speakers can't as can be seen with the ML panels.
April 22, 200818 yr The bias isn't high enough nor the charge strong enough to do anything like that. Even electrostatic speakers can't as can be seen with the ML panels. If an electrostatic headphone is powerful enough to do that, I'm not sure I want it on my head.
April 22, 200818 yr If an electrostatic headphone is powerful enough to do that, I'm not sure I want it on my head. Wuss!!! I've been zapped plenty of times and you can barely feel it.
April 22, 200818 yr Wuss!!! I've been zapped plenty of times and you can barely feel it. But you weren't using headphones that can vaporize dust particles.
April 22, 200818 yr Wuss!!! I've been zapped plenty of times and you can barely feel it. Now this may explain some things!

I always remove the membrane before vacuum cleaning my drivers, so thats not an issue. I don't think its dust, but I'll have another look.
April 23, 200818 yr Now this may explain some things! you've heard of the Stax fart... now presenting.... the Stax lobotomy
April 23, 200818 yr Actually, wouldn't that be Stax Electro-shock therapy? And thanks for setting me straight -- makes perfect sense that they're different voltages.
April 23, 200818 yr Good news on my part, I've been running them all day at work with an SRD-6 and even though it's low bias they still sounded fucking amazing and the buzzing is gone for now. The speed and solidity is outstanding, probably partly due to the lightweight but very rigid enclosures and solid driver mounting. I'm hearing some outstanding speed and resolution. Bass all the way down to an easily audible 20Hz
April 23, 200818 yr The Smegma Pro lives! Just been running them from the SRD-7MkII and it's been mindblowingly amazing. They pack a hefty wallop and rattle the ears. Yes they have as good an impact as nearly every phone I've heard less one or two. They are fast as lightening, clear as a bell with explosive dynamics and they go deeeeep. Fuck these are good! They beat everything I've heard to date including the K1000, HP-2, Leatherhead.. Fanfuckingtastic!
April 23, 200818 yr Brilliant Smeggy! Glad you're loving it. Got any pictures showing us how its put together?
April 23, 200818 yr This is where you become a MOT and make your Smegma available to the general public.
April 23, 200818 yr Thanks. This is where you become a MOT and make your Smegma available to the general public. Hehe, noooo I don't think so Brilliant Smeggy! Glad you're loving it. Got any pictures showing us how its put together? Sadly, no. It's a bit of a mess as the glue I was using expands and makes a hideous yucky sight. Sadly I didn't know it was going to do this and certainly wasn't expecting it. Oh well, live and learn. Thankfully the sound is amazing so that makes up for it.
April 23, 200818 yr you've heard of the Stax fart... now presenting.... the Stax lobotomy Maybe I should market that, you know to secure my investment... I always remove the membrane before vacuum cleaning my drivers, so thats not an issue. I don't think its dust, but I'll have another look. The dust is almost always stuck to the membrane. Only dust and the charred remains of arced mylar make this sound but basically look for anything that is protruding close to the stators and will move once the high voltage hits.

The Pro drivers are large step up from the normal bias units in impact and bass quantity. One question though, how did you mount the cups to the headband?
April 23, 200818 yr Very nice!! The Pro drivers are large step up from the normal bias units in impact and bass quantity. One question though, how did you mount the cups to the headband? Honestly, it'd make you cringe it's so botched up I took some gamma forks and removed the plastic leaving the pins with steel spade ends, I cut a slot in the top of each cup and glued the spades in place at an angle so the pads meet at the base for a good fit. It's pretty ugly but effectove and very solid.

It's pretty ugly but effectove and very solid. Very cringe worthy but if it works its all good. You could also do something similar to the SR-? arc where there is an additional plastic bit added to the bottom of the arc and the wire holder attached to it.
April 23, 200818 yr Hehe, noooo I don't think so fftt.. he doesn't even use Dynamat. If I was going to use something, I'd use bituman sheets. I've used these for speaker damping and they kick the crap outta any other damping sheets. They are quite heavy, so it would make the customers feel like they're getting more for their money.
April 23, 200818 yr Here's some prototype pics of the KGBH SE. I plan to bring it to CanJam in a week w/ a pair of black O2 MKII on a Sony SCD-1 ^bling option ^MOT
