Absolutely. I'm going to have to put some clay around the edges to make a seal as well, I just haven't gotten around to it.

Have you given up on the Alpha pads?

Actually, I suggested this to you last month in the big T50RP thread :)

 

It's at this link if anyone is interested, Post #10083.

I have for the time being, but I don't plan on getting rid of them. I'm hoping that my buddy can fine tune them to sound about the same as mine. Since we both don't have any way to measure FR, the easiest way is to just have a set that already sounds awesome so that we can compare. He's a slacker though. He's spent the past couple weeks deciding how he wants to paint his. They will look awesome when they're done, but I just want to use my Alphas already!

 

It's a good stopping point for me though. I just got my HE-400's and I owe them quite a bit of head time before I want to dive back into the modding.

You never mentioned to try a hole as small as 1mm in diameter. You mentioned to try in 1mm increments, and that your sweet spot was 4mm. 

 

It's no big deal, no harm done. No disrespect.

Definitely stick it out and try. If Mr. Speakers can utilize these pads as he does, then we can at least try and get close. It is possible to get them working well with these pads.

No offense taken or intended, just information. It's all good.

 

The first I've read about anyone making pin size holes in tape over the external cup vents was wdahm519's post or email (I forget which) some time last year. When I read he got good results with 1 or 2 pin holes, I first thought "no way." I tried it and found that he was correct...a single millimeter difference one way or the other can make a noticeable difference in sound quality.

 

I usually start out with a 3 or 4 mm bass port and then increase or decrease the size in 1 mm increments. Some mods, even if apparently done the same way as another, may require a 1, 2, 3, or 4 mm bass port. Others I've done needed nothing more than the stock black felt over the internal cup vents. The only mod configuration that I've done with sealed cup vents, that sounds good to me, is the Grodan rock wool mod and some of these I've done needed some degree of venting.

 

I'm just happy that you found a tweak that worked for you.

I should send you my Fostex/COP transplant so you can play with the variable bass vents rolleyes.gif

Yes, you should! LOL

 

I'm currently transplanting T20RP mk2 drivers into the "CopperHeads" you sent me. Had to steal a set of baffles from a "Naked Driver" experiment. In the middle of soldering the pigtails. The Left side works...now on to the Right channel.

 

Cheers!

Didn't I send you baffles with it? I thought I put them along with all the screws in a ziploc bag.

I don't remember. I'll check all the boxes. LOL
post #612 of 1151

I remember spraying the cups with rubber, and I think I did the baffles too. Probably tucked away in the boxes somewhere, lol. Should be with the rods and rod holders (which were also painted).

Damn, these are definitely my new reference. They sound so natural, so textured, so detailed. The bass is now controlled with just the right amount of warmth. Bass is snappy and very, very extended. Probably the best bass I've heard from a headphone now. The treble is neutral and very well extended, it's actually very sparkly. Cymbals sound great. I have no complaints with these now. The soundstage isn't even half bad, definitely not as wide as the Q701, but whether which one is the more accurate presentation is subjective. Imaging is definitely more precise on the T50rp. Binaural on the T50rp sounds way more accurate to me, binaural on the Q701 seems super wide with very limited depth.

 

I wish I could measure these just to see what I am hearing. I'd be interested to see the top end on these compared to the top end on the Q701, because my T50rp with it's current tuning really isn't dark anymore. I'm not hearing any sibilance either, so I'm likely to think that the top end is relatively smooth. They seem to me like they actually have more sparkle or detail up top than the Q701. The upper mids on the Q701 seem to be more dominant, and my T50rp seems to sound more neutral in the upper mids and simply extended more smoothly on the very end. I am definitely hearing more of the cymbals in rock and metal recording. 

 

If I could draw a graph of what my brain thinks I'm hearing, it would look a lot like the graph for the latest version of the Mad Dogs but not as dark. Kind of like an HD650 with a more extended sub-bass, and a little more top end and better top end extension. 

 

EDIT: Listening to Tool's Lateralus right now and holy crap this sounds gooooood. I've owned this album for quite a while, but never really gave it much attention, but right now I am wondering why. The drums sound stunning. Great recording, and these cans really show it.

Sweet. This is great news!

Have you considered making a measurement kit?
post #615 of 1151

How much would you say it costs?

 

I'm not sure it would benefit me any at this point though. I have them dialed in to where I want them, and I doubt seeing a measurement would make me change anything about them.

 

I really should be sleeping right now, I have work early in the AM, but I don't want to stop listening. L3000.gif
