Shure SRH 940 impression and support thread - Page 52

post #766 of 3844

Also, no idea what you are reading, the graph clearly shows that the 840 have a clear mid bass hump and 940 have a clearly more midrange and extends better in the low bass, and square wave response are different too,.

 

If one compares both shures measurements with other headphones it should become apparent that both square wave performance isn't that different and that both FR curves share the same mids - treble peaks and valleys...

Their electrical impedance and phase curves are also similar, their impulse response also similar pattern...

 

This is what leads me to believe that they are using the same driver...

 

But to truly confirm this somebody who owns both HPs would have to open them up and see how they differ.

This is what I'm begging for.

 

IS THERE ANYONE WITH THE WILL TO DO THIS?

I'm on my BlackBerry so I can't post the pic. But if you click the link you'll see the faceplate of the driver housing is the same. The 940 on the left and the 840 on the right. The drivers look the same except for the red ring in the middle of the 840 driver. Even the grills are the same configuration.

My guess is the drivers that measure better go into the 940. Then Shure adjusts them to get the frequency response and characteristics they're after for the 940.

Grado does the same thing throughout their line.

Thanks for the pics.

 

I'm not sure at what part of the headphones I'm looking at...

Did you just took off the earpads or did you actually opened up the enclosures?

 

I'm not sure that this pic is enough to absolutelly confirm that these are the same or different drivers unfortunatelly...

What's on the back side of those structures?

 

Do I see some screws on the faceplate?

Aren't those screws begging to be unscrewed? ;)

 

COME ON PEOPLE!

WORK THE DIRTY WORK!

IT'S SCIENCE TIME NOW!

I just took the pads off. Believe it or not I don't think a have a small phillip's head to unscrew them. I'd fear stripping the heads of the screws. :( Science will have to pause until I either find the proper tool or if someone else does the dissection. lol

Strip of the screws heads?

Stop being lazy and get the job done, lol!

Any knife or small coin should do the job...

dissasembling them has risks and you risk voiding the warranty. why would any of us risk that. that is unless we are professional diyers which i doubt. maybe some of us are. but it would still void the warranty.

I'm sure it was in jest. I certainly didn't take it seriously. lol

All kidding aside bcasey25raptor is right about the warranty and I am not overly skilled. If I had the proper tool I'd unscrew the plate and take a peek. I'll look around the house and see it I have one buried somewhere. If the drivers are held in place by plastic clips I might not want to risk taking them apart. Plastic breaks.

WhoTF cares! The sound from each model is very different, not even close.

Just take me lightly, guys!

Obviously no one is being forced to open up his or her Hp.

 

Whoever do this should be highly skilled with this matters.

If one is not confident enough or if one simply doesn't want to open the headphone, then just don't!

 

NO BIG DEAL!!!

That's exactly why I'm so interested to know if they are using the same drivers.

Because if they are, then I would like to know how such disparate sound is possible from closed enclosures.

Not that I pretend to buy any of these Hps.

I just may be able to use such knowledge to some future modding.

 

JUST IGNORE ME IF YOU FEEL SO!!!!!!

SELFISH MODDING CURIOSITY!!!!!!!!

Click on the links. The drivers themselves are held together with plastic clips which I didn't attempt to disassemble.

Someone please be kind enough to embed the four pics in the thread for me. Thanks.

baka1969, you are my hero!

Better leave it that way if you're not confident!

 

Those pics don't show any foam nor felt inside the enclosures... are those enclosures undamped?

Or did you find some damping material inside there that you didn't get to pic?

 

Aren't there any numbers or inscriptions on the back of the drivers?

 

Looking at the enclosures interiors I see that the gray enclosure (940?) is widther than the black one(840?).

Is this the only relevant physical difference between both headphones?

 

Thanks!
