It does for those who are accusing Grado of taking the same driver and just adding a ring to it.

It would be nice to know the facts.

Edit: Focker, their response to you didn't elaborate about the size.

The word "accuse" is so loaded. The drivers are new. They have different efficiency levels than the old ones and people have done a few side by side comparisons and they do apparently sound different or better.

But the pictures in front of out faces don't back up the size claim. It's not coming from thin air. If it weren't for the super clear and detailed pics of the rs1i (surprise e models from early sales) I wouldn't even have had any doubts about the new driver sizes.

And driver size does matter if you're interested in the possibility of reducing distortion for bass frequencies and bettering bass extension. So naturally we should be curious.

For the PS500 the visible outer diameter is 46mm. Seems like there is enough room in there for a 44mm driver.

On any of these headphones they have room for a larger driver without making the housing bigger.

Guys, we are here to discuss headphones, not people. Please avoid getting personal. Thanks. :smile:

Thank you for taking that picture and measurements, Sense

I have an old buttoned rs1. The outer diameter of the plastic housing is also exactly 46mm.

In addition, The open portion with white cloth is the same for both my 40mm rs1 and your 44mm ps500e. This is the part that really determines the size of the driver.

See why this is odd? I mean, I guess there is a chance for odd geometry where the driver is bigger than the opening in front of it but these things have been straight cylinders forever.

Seems to measure 45, with a plastic ring of 2 or 3 on each side, which gets us back close to 40.

Until someone is willing to take apart their new e-series cans, you might just wanna contact grado directly via

email/phone (http://www.gradolabs.com/contact-us), twitter (https://twitter.com/Grado), fb (https://www.facebook.com/GradoLabs) and ask for some pics with measurements of the driver sizes.

 

All the rest of the speculation here are not going to help much.

Yeah, I was more trying to have them address the suggestion that they took the previous driver and added a plastic ring to it, thus accounting for the difference in size. I didn't think to ask if John Grado knew how to use a ruler or not.

Measurements are not speculation. Measurement is data.

I was going by the dictionary. Anyway, I intend to buy an RS-1 in the series, maybe an SR225e as well. I'm curious to see if there is an improvement in sound quality.

Driver is butted up to the edge of the hole in the casing. The buffer around the driver that allows it to move (sorry if I'm not using technical terms here) appears to be extremely small.

I don't know if this adds anything to the conversation but in the end I believe this is a conversation about something that no one has any real knowledge of since no one has taken theirs apart.

Also, it ultimately comes down to what the industry standard is for measuring the diameter of a driver.

I remember reading that they had to make the walls if the casing thinner (I.e. Make the holes in the casing bigger) to make room for the bigger drivers.

I adjusted it to try and make it more visible. Tapatalk won't let me edit posts here for some reason.

What I would recommend is contacting Grado directly, and that way the information will be accurate. They don't use 20 year old drivers. I confirmed this a year or so back in the Grado thread when it was brought up by someone else. And what they stated in my most recent discussion was fact, not rhetoric. They stated that the drivers are redesigned and they gave two specific examples of what was different.
