My DIY electrostatic headphones - Page 79

Unfortunately, open area on the stator doesn't affect it's efficiency.

Thanks in advance for sharing the dimension info with me. smily_headphones1.gif

I am wondering, what warrants the high prices on headphones like the orpheus and sr-009 if you look at material costs?

It's more of a market niche and peace of mind, IMO.

I thought so. Thank you for clarifying.

you might try asking some of the builders what hours they've sunk into their projects - and how far from finished, commercial quality they are

 

how many $k if they billed at competitive rates for their labor - including the failures, blind alleys, just redoing as skills improved

 

capitalisim really does work - special knowledge, skills as well as tooling, even distribution channels are worth premiums over raw parts cost - how much does the raw metal and plastic for a modern automobile cost?

 

 

and sales volume has a big impact all fixed costs, overhead are burdening the fewer sales - ES headphones and amps would cost a lot less if the market were millions of units instead of thousands a year

Hmm. I understand the point as you intend to make it jcx, but I wouldn't be entirely happy about making such a bald statement when we've all (all of us ordinary wage slaves and hobbyists) taken such a financial beating at the hands of those with the greatest responsibility for working the controls of the capitalist system...

Then there's the fact that many would judge audio electronics to be possibly the most dysfunctional industry imaginable.

I don't entirely disagree with what you're saying, I just think we all need to take a bit more critical view of the capitalist system than giving it the wholehearted endorsement of saying 'it works' without some qualification.

I don't want to see one of the most interesting threads here dragged off into an argument though, I really wish you'd found a less potentially contentious route to make your point.

While I agree that the traditional definitons of "capitalism" no longer describe our global financial climate, I dont think that really applies to audio companies. 

 

Work the numbers back, I think you will see his justifications line up - following traditional definitions & guidelines of "capitalism."

Another thing I tried while bored in the shop a few weeks back was making huge holes just to see what would happen. I ended up going with kind of what planar magnetics are structured like.

 

They sounded absolutely terrible. Severe bass roll off, basically they ended up being tweeters. Unfortunately I don't seem to have the frequency response anymore, but it was pretty horrendous in the bass department. 

 

I didn't know what to expect, but certainly didn't expect them to be as bad as they were. Why would the roll off be so extreme? My best guess is the higher frequency modes propagate across the entire diaphragm while the bass frequencies are unable to and end up being only locally driven where the electrodes exist.

That's interesting. I can't think of any good reason for such a bad roll off in bass. Thanks for sharing though.

I am thinking above design might creat constructive and/or destructive interference on the diaphragm as it isn't a uniform electrostatic field with that configurations. Not that I think it has anything to do with the bass but it might lead to resonances?

Hi,   I'm a novice with regards to using this forum - what I'd like to do is correspond with you DIRECTLY about my Stax NEW SR-3 headphone problem.   How?     Den.

Hover over someone's name and click Send PM. Some forums require a certain number of posts before you can PM, not sure if this is one of those.
