Hello--
I recently acquired a pair of Stanton Sixty-Five four channel headphones. For whatever reason, all 4 speakers are blown out in them... I am in search of replacement drivers, and have it narrowed down to two different ones (i think). I am just looking for opinions on them, or possibly another suggestion of speaker choice. Original driver diameter is 40mmx17mm(?) (dont remember depth, but there is spare room behind the speakers). I initially tried getting help from members in the diy section of head-fi.org, but apparently no one knows nothing about speakers on a forum about headphones 😕
I havent decided how to wire them up yet either. There is a switch in one of the cables to go between stereo and quad (has two quarter inch plugs for quad usage), though I am not sure if stereo parallels the speakers or just disables two of them.
Also, would it be worth plugging the air ports on these, or possibly adding sound material behind the speakers? On my Sixty's, I ended up replacing the blown 2 way dynamic speakers with 2 way car speakers, and plugged the airports based off a really old forum post that said doing so really helps with lower frequencies. I don't have an unmodified set of sixty's to compare against, so I'm not sure if plugging the air ports helped or not...

I like these cause they have the lowest Fr, and have the most data available about them Frequency response seems decent as well. If they were paralleled, that should bring the resistance down to a reasonable 16 ohm.
#2. Access Denied
Similar to #1, though the frequency chart is blank :/
I know nothing when it comes to speaker choice, so any and all input on the matter would be greatly appreciated! 🙂

Yes headfi ,as a poster there said (dealer ) has changed from diy help and "followed the money " morphing into a commercial enterprise where email invites are sent for you to attend audio shows .
I have some hifi year books including the "quadraphonic era " of 1973--- 1974 ( approx ) but none of them have Stanton headphones and yes Gibson bought Stanton but inmusic bought it from Gibson , at the time of your headphones though I think Stanton was still self owned .
Koss sold 4 channel headphones at the time but as Stanton is a US company as is its owners now maybe a US poster here can help as those headphones don't appear to be of great appeal in the UK ?

Just go ahead and get the #1 drivers. I'd probably only replace the two front ones.
Do add some stuffing inside, it can't hurt. The impedance won't be a problem either way.

Heres the magazine that compares them. I originally found it cause I also have a pair of mura qp-300's

Cool. What kind of stuffing should I use?
Just bought 4 of the #1 speaker. Interestingly enough, googling the number brings up a head-fi post about someone using the same speaker to repair some junk Sennheiser HD-280 Pro's that he got. Will have to run to joann's to get some wool for the cups as well. Will post an update when I get them installed.
Also, just as a note, the quad / stereo switch paralles the speakers when in stereo, according to the magazine in one of my earlier posts.

Make sure each pair of drivers is connected in phase, both between the drivers in a cup,
and between the two cups. Just use the + terminal of all drivers for the positive lead.
In the parallel switch position, there should be more bass.

Will do. The speakers are soldered to a terminal strip in the cup. Though, I will make sure everything is in phase up to the switch since I will be using them in parallel 99% of the time.
It is tempting to rewire the quad mode so that they can act as true surround sound. I could be wrong, but I believe the old school quad is wired to have all front in one cup and all rear in the other. My quad amp is in disrepair, so the likelihood of using these in old school quad mode is slim.

That's not how my neck-breaker KOSS quad was wired.
It would sorta spoil the stereo, eh?

Got the speakers in and installed! Should have gotten speakers closer to 45mm, though the ones i got worked just fine. Sound response is...okay. Not much in the sub bass area, though that is to be expected as these speakers can't really really do much effectively below 80hz. I'll probably use them occasionally as they are much more tolerable to wear over the Stanton 60's that have car speakers in them xD
For the sound deadening, i just cut a sock in half, folded it a few times and crammed it in each cup. I know, not the best thing, but my main goal with that was to block the air vents off to help the low end a little more. Plus, I didn't feel like driving through rush hour traffic just to get some wool. Until next time... 🙂

If you get to experimenting with different drivers, peerless make a very good headphone driver that can produce some serious bass if implemented correctly.
Parts express had them but they appear out of stock
https://www.parts-express.com/Peerless-HPD-50N25PR00-32-2-Headphone-Driver-Diaphragm-264-1510
There is a 2" and 1 1/2" version.
If you like the idea of multi drivers, look out for vintage AKG, not Quadrophonic however.

Huh. Those look very similar to the ones I just installed. Like, almost identical. Wonder how they compare...Also, the second link in my first post (that says access denied) are also peerless speakers.
What model AKG should I look for? I mainly got the stantons based off looks. The next pair I think I am going to snag are Pickering ph-4955 -- the woodgrain variant of the stanton sixty's.

I think I am recalling modified AKG 240 with a crazy number of drivers. The stock version looks like it has a single driver with 6 passive radiators.
Burn a little bit. Wool smells like burning hair. Plastics don't. You can find burn-charts. Polyethylene burns like wax, and sooty. Polystyrene (not a sock-stuff) has a spectacular soot pattern. Most plastics drip (watch your skin!!).
"plain white socks" today are probably an acrylic blend. Better than nothing, for feet or for boxes.
