Shure SRH 940 impression and support thread - Page 53

post #781 of 3844

Ops! My first double post!

 

 

Still not sure if those drivers are indeed the same or not...

Maybe different versions or tunnings of the same driver...

The drivers themselves are held together with plastic clips which I didn't attempt to disassemble.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!"


Nope. No dampening material. Just what you see. The grey is the 940 and the interior dimentions of the cup's interior seem to be the only differences. My semi-educated guess is the drivers are very similar if not from the same family. Again, this shouldn't be a surprise as this is a practice Grado uses.

I think it would be interesting to mod the interior of the cups by using foam, felt or Blu-Tack. I would bet though, that part of the difference in the sound between the 840 and 940 is the design of the cups interior. That said, I wonder if a little Blu-Tack or felt would increase the bass impact without messing up the entire balance or sound quality?

Maybe I'll give it a whirl...?

Thanks, baka1969.

 

I guess that's all I need to know...

Seems like you've opened the window for modding possibilities on the Shure housings, that would be interesting for sure.

post #784 of 3844

Oh, just one more question.

baka1969, are the back side of both drivers exactly similar?

Isn't there a difference on the numbers of vent holes?

post #785 of 3844

If you're thinking about modding an 840 into a 940 I think you're out of luck. The entire srh line measure pretty similarly and seem to have pretty closely related drivers, I think there's a lot more to it than enclosure tuning. If you listen to the 940 the drivers are much faster and just sound completely different.

If you want to increase the bass a little you could also try stuffing some thin pieces of cotton under the ear pieces. I remember doing that to a JVC rx700 tilted its sound towards the warm side, but too much completely wrecked the tonality. Worth a shot maybe?

Maybe if I have time tomorrow I'll pick up some silly putty (it's easier to get quickly than Blu-Tack for me) tomorrow and experiment a little. I'd start with the 840 just in case I mess it up.

If it's possible to flatten out the mid bass hump of the 840 with a mod, that could make the transients sound faster because the bloomy bass wouldn't interfere and possibly might make the leading edge of the notes become a bit sharper. Just a thought...

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

 

They are now embedded! a bit late dough...

Maybe? I really don't know anything about enclosure modding. It would be pretty hilarious if your mod worked out though.

 

I guess even something like a larger port could allow the driver to draw more air and move more freely.

I was noticing that there is a lot stuffed behind the driver already. None of which seems to be encased or placed with precision to account for acoustics or backwave. That has nothing to do with porting the back of the cup of course. It just doesn't look like a fine tuned instrument behind the driver. I was thinking or wondering if fiber fill would diffuse the sound waves and evenly distribute them in the back of the cup?


Oh well, if I get the chance tomorrow I'll see what happens with the putty. I can rip apart a pillow if I feel the adventure takin over me. Lmao

There is always such big hype on new products which are the best on the world at that time. I currently own dt1350 which are generally at the same price point and are also described as great. whats wrong with that question?

 



Steak and lobster. What's wrong with that answer?

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?

 



This is like begging Brad Pitt to disclose who looks better naked, Angelina or Jennifer. I'd rather find out on my own.

How do they stand up to the AKG K 701?

post #794 of 3844
