Markl type mod for the audio technica ath-m50?

post #1 of 14
Thread Starter 

First to disappoint you all. No, I did not create a markl type mod for the ath-m50, sorry for getting your hopes up. Now for the point of the thread.

 

The problems that the markl mod fixes in the Denon Dxk line seem to be the same problems that many people have with the Audio Technica ath-m50's: to much bass and recessed mids. So lately i have been thinking -- what if someone were to create a markl type mod for the M50's? Have any of you tried to create such a mod? Discuss!

First, the cups cannot be replace, easily anyhow. Then someone would have to make leather pads that cost almost as much as the phones. Then the cable would cost more than the phones. You can already put tape over a couple of holes to reduce the bass. You can replace the pads with shure 840 or 440 to reduce bass, bring the mids forward a tad and largely increase the soundstage at the cost of isolation. It's just not cost effective to put $300-$400 into $100 headphones.

ok, what about the dynomat part?

If you want experiment with dynomat you can or if you don't have do a search for blutak mods as an alternative. Also look for AT ES7 and ESW9 mods for ideas as they both have a couple good mod threads.

Or just put tape over the holes...

search 'balance mod'

I don't like the sound the balance mod gives. sure it lowers the bass impact, but it sounds kind of like something is missing

Well...because it is?  Depends on how many holes you cover and what material you use to.  The quickest easiest mod that also adds comfort is just swapping for some 840 pads.  Though some didn't hear a difference.  As always YMMV.

     I'll probably end up trying the 840 pad mod -- it sounds interesting -- but I'm still going to look into the idea of using dynomat. I believe it might be a better alternative in terms of sound quality than simply covering up some holes with tape. It might even be a good idea to use dynomat and cover up some holes. Think about it this way, when you cover up the holes, you decrease the surface area that the sound waves have to flow freely from the head phone. This inherently increases the area which sound waves have to hit the inside of the cups. when sound waves hit the cups, not all of them are going to be absorbed by, or pass through, the solid medium, so they bounce back into the cup. Since there is more surface area for the waves to hit, more of them are bouncing back into the cup before. Now these waves going back into the cup interact with new waves moving out of the cup, thus making everything more murky. However, If dynomat was to be added to the cups, more of the sound waves that hit the cup would be absorbed, hence less waves would bounce back.

    I'm no expert so I can't tell you my musings are entirely accurate, and I would be glad if an expert on the matter would come and correct me if I am wrong. If I, however, do happen to be correct with my thinking, adding dynomat to the cups would have an accurate outcome.

You are correct. I noticed a little more resonance in the cups after plugging a couple of holes. Some poly fill or dynomat in the cup might be worth trying to tighten the bass, but the slightly recessed mids might become even more so.

hmm, if i had some dynomat i would try it. What about putting dynomat in the cups by where the ear pads are, and then poking holes in it to let sound out the ports? It could also simulate the tape mod if we where to not poke holes for all 14 bass ports in each cup. Then the dynomat would absorb some of the waves hitting the cup, reducing resonance from the source

I have been thinking about this as I do some woodworking. Im just waiting for some M50s to arrive...

As was pointed out in the Fostex thread, Dynamat is for controlling cup resonances not absorbing back waves.  I would try the pads first as rolling pads are like rolling tips for IEMs IMO.  See which you like first then go from there.

by absorbing back waves, it would prevent the resonance, thus controlling it. however if i do get my hands on some dynamat i will try that, thanks for the advice.
