"Mad Dog" by MrSpeakers, modified Fostex T50RP review - Page 409  

post #6121 of 6388

I don't want to derail the thread or anything, and I know you are in the business to do your own mods and make money. But if you are willing to give out a little info, my question would be how to remove some in the 125-500 hz area. I don't have your Mad Dogs, I just have your Alpha pads on my own modded T50rp, and I'm completely happy with them after I EQ about -2db at 125hz, -4db at 250hz, and -2 at 500hz. Any idea what mods I could try to reduce the response in this region? If you can't or won't answer this I understand, I know you are in the business to do your own modding. Any help would be appreciated.

I get questions like this by PM and answer when I can but it's hard to answer this question without knowing what mods you've run.  Usually this region is managed by tuning down the felt covered vents.  If the peak is large, experiment with electrical tape on the outside of the vents closing them down until it sounds optimal to you.  Usually 100% closed is too much, but mostly closed works best.

 

For other mod questions post them on the T50 mod thread and PM me to let me know you have a question...  I can't handle huge volumes of questions, but am happy to answer them once in a while...

Thanks so much. "Modified bass port" is the answer I keep hearing, but right now I have a piece of masking tape over the outside vents with just a tiny pen tip sized hole poked in each side and this seems to have helped but there is still too much in the 125-500hz area and it sounds bloated, muddy, and congested there. I don't have a metric ruler or caliper or anything, but it was just a standard "bic" pen that I used to poke the hole, I'd guess maybe 1-1.5mm is the size of the hole I have in each side.

 

Inside the cups I have a single layer of stiffened craft felt over the driver, 6 cotton balls per side, and the cup floors lined with adhesive backed felt. 

 

The inside baffle is mass loaded with a non hardening modeling clay. The baffle port was covered and then poked with a small needle. The area around the jack and where the wires enter the cups has been sealed with silicone. 

 

Anymore help would be greatly appreciated. If you want me to take this to PM's I will gladly do so.

 

Thanks!

Thanks for the measurements as always, Dan! I think the 3.2 revisions look encouraging, and I'll definitely be sending in my headphones for tuning once I move out to Colorado at the end of the month and get settled with my new job. :)

The measurements looks just about like I pictured them. Thanks for sharing!!

Good luck man!  Does the new job me more money for music?

Thanks for the graphs and descriptions of the sound between each version, Mr. Speakers!

 

I must say that the more time I've been spending with the Mad Dogs, the more they are really growing on me. I'm finding that they actually sound quite nice at lower volumes on my portable amp, and with their amazing comfort they are the perfect headphone for winding down at night. I think they have found a new home on my night stand next to the bed. I'm really interested in the 3.2 upgrade now...

 

Last night I had my first real WOW moment on these cans while listing to this track... I was all, "ooommgggg that bass!" L3000.gif

Thanks for the graphs, Dan.

Sorry it took so long...

Not a problem. At the least, you've solidified my upgrade! smily_headphones1.gif
Through my simulation of what they'd sound via EQ, I can say I think the addition of a few dB in the 4k region will be quite appreciated to me personally. I was worried that the lowered mids right ruin what I like about the MD, but instead everything sounds cleaner and crisper.

Thanks! I need to prioritize paying off student loans and my "new" car first, but...yeah...I'll be making decent money, and I'm sure some of it will get funneled into music and audio gear one way or another!

The Alpha Pad smooths the peak from 800-1.5K, ads some energy to the upper mids and lower highs, and has a less output around 8-10K, perhaps owners who play with EQ could comment on these changes

 

I won't comment on the sonic changes, as I don't wish to present a biased message and will leave commentary on the sonic affects to any users who do the pad swap.  The pads did have the Alpha feel, but the overall experience of the fit and sound of the phone is quite different from the Mad Dog.  

 

Hum... why didn't I try this BEFORE selling the 500s? ...

I got really good result with the 4s and 5LEs with Alpha Pads. The comfort is much better than any Hifiman stock pads (velour first) but the fit is quite loose due to the headband having not enough clamping, I suppose.

The MDs have a better and safer fit.

 

The 3.2 seem to fix the fews grips I have with the 3.0. I might get the balanced 3.2 when I reach the USA (better deal than in Europe) by the end of this year.

In the meantime, I ordered a TH-600, for fun (expensive).

You can see the 3.2's upper range bump, which is audible. That's maybe the reason some S sounds can be artificial sounding, though at the end of it all, I greatly prefer the 3.2 over the last one I tried (believe it was the 3.0).

Just listened to the new Daft Punk album on the MD's. Wow...eek.gif Great album, great sounding recording and man does it sound sweet on the MD's. I love how the MD's linear bass steps up and delivers the deep heavy bass in this recording. Most of the hp's that I've owned have not been linear and the sub bass here would have been too much. But the MD rendered the Daft Punk record with tight and punchy and heavenly deep. biggrin.gif

Please at least save a Mad Dog for me, I am going to order it after months. I found out LCD2 is out of my range and pay attention to this Mad Dog biggrin.gif, hope the price is not going to go up. Like this topic.
