Q701 impressions thread - Page 245

post #3661 of 9490

Finished the mod like 30 min ago. The increase on bass is noticeable, it´s not something like "the bass seems...". The sub-bass is much better, I would say an increase from 3 to 6db from sub 100Hz. Midbass is boosted as well. The most impressive thing is that it remains crystal clear, not bloated or grainy. 

 

With respect the mod. It is fairly easy, it was a pain in the ass to remove the plastic pieces because one of the two tabs got well stuck in both sides. I had to use a knife to help them to come out. I recommend everybody to remove that part from top to bottom, removing first the parts that attach it to the two black sticks.

 

Some pictures in case it helps somebody:

I think this mod does increase subass, but slightly decreases the midbass which makes the midrange even more withdrawn, and definitely more incoherent. Definitely, YMMV, and my ears are my ears. 

 

I kind of agree with most of your comments, the only difference is that I think I will keep the mod. :D

Certainly is an interesting mod. I could definitely see how someone people would really like the changed sound, but as I listen to a lot of classical and acoustic type music, it's definitely not for me:D.

 

The really low frequencies definitely get a little kick down low.

Just got an email from Quincy. He said all us sacrilegious bastards are off the guest list for his next party.

I'm not entirely convinced, either, though I want to give it a little more time. It sounds like you were able to get the covers back over the bass port. Can you describe in whatever detail you think appropriate how you got them back on, or whatever you did to reverse the process? Is there a way to completely expose the port so it's fairly simple to line them up?

 

Thanks.

I modded only one side on mine, and then did a side by side comparison, before committing to the other, so I got off a little lucky. I ended up taking off the 1. top grill circle  2. piece that goes over the two poles (and 2 screws)  3.  Large plastic piece that holds the headband to the cup (1 big screw).

 

With a lot of patience and really tiny tweezers I was able to get it back into place. Make sure it completely covers the hole AND that you pat it down a bit to get a good seal.

Clever ;-)

 

So, no way to really expose the whole port. Otherwise, you did what I assume I'll have to do, if I reverse it. I've got some plastic toothpicks that are angled on one end, so maybe that will help with the hidden portion. At least the covers are intact and still sticky.


Thanks.

To expose the whole port would require unsoldering the leads and then soldering them back on, which I wanted to avoid. It can still be done without soldering it up. Once you open that cup, there's no doubt a German engineer had a hand in making these.

I think this even improves classical and acoustic type music for me. Much more spacious sounding. Really almost speaker like.

Strange but I didn't notice much very low bass increase. "Koyaanisqatsi" still sounds pathetic on the Q701 and HD-650. I think that goes pretty low but not sure.

If there was a 1db increase I'd be shocked.

 

For me there's not a dramatic boost in the bass. I think it just is very very accurate still and there's just more bass impact. If it's not supposed to be there it won't show up (for me).

 

You can find music that has bloated bass in the recording (Why does this even exist?!) and it sounds the same on the Q701.

 

Also for me the mids got slightly fuller sounding but not shoved forward at all. About the same as before. The "Annie" low mids are much more forward, but not as full sounding.

 

I would say right now the low bass is almost identical in quantity to my HD-650.

 

Right now it sounds like an HD-650 mixed with a K702.

 

Some may think the mids sound more distant but IMO it just due to a more accurate soundstage. If you listen to live Pearl Jam songs they're awful (Dissident Live is unlistenable) and you can barely hear the vocals. It sounds like the songs were recorded from 50 feet away. Not the headphone and sounds similar on the HD-650.

I want to do this so bad but I'm scared to ruin my week old q701's. I was tempted to buy HD598's to see if i liked them better but this seems to be exactly what i want. Someone should make a video for cowards like me lol

2 questions:

 

1. Why did AKG put this little dot there to begin with?

 

2. Why have I not seen this mod before? The K/Q701's have been around for years and just now somebody tried this?

 

The result for 5-10 minutes of work is impressive. Not only does it add bass, but it makes the bass sound better as well. I have always boosted the bass on my Q701 by 2-3DB, but now I don't have to. This mod does more than just add bass anyway. This mod seems to also improve bass impact and makes them sound more speaker-like. Pretty much like has been said, it seems like AKG overdamps them, and now this is freeing the driver up to do what it should be doing.

BTW did you try this mod with the AE, K702 or Q701?

 

I bet it WOULD be bloated on an AE, but I've never tried that.

 

Q701 has foam behind the outer grill after all..that kind of limits some things perhaps.

trying this now

The way I did it was: 

 

1. grab two toothpicks to use to twist the outer grill off

2. use a 3rd toothpick to slowly peel/pick the edges of the little white dot

3. use a pair of tweezers to gently lift the white dot the rest of the way off

4. reassemble

5. repeat for the other side 

 

******I did not take it apart any farther than just twisting the grills off.******* 

 

If I had to guess I'd say this adds maybe about 2-3db from about 100hz and lower, and adds another couple db below 50hz on top of that as well. It definitely adds more bass overall, and definitely extends deeper with more authority. I hear no negative effects, and so far I see myself sticking with this mod.
