post #10681 of 11259

Care to share about what holes you're talking about. I may pick up a M-Audio HDH50, maybe it just has different venting config inside compared to the AKAIs by default. :)

EDIT: Wait isn't these the AKAI you've got? Seems like so as it's the same specs as the M-Audio only 1 EUR difference between them (AKAI 1 EUR cheaper). 

AKAI MPC: http://www.thomann.de/fi/akai_mpc_headphones.htm

M-Audio HD50 http://www.thomann.de/fi/m_audio_hdh_50.htm

Maybe it's the pics fooling but the M-Audio's pads do look slightly higher quality.

:blink:

 

They are the identical pads. specs. I think it's some optical illusion.

 

 

 

Same pads, same backing cups. Can you point out the part that looks different.

I'm not clear on what mod you did HBB.

 was told if I wanted more low frequency response I should remove the material surrounding the back of the driver at 11 and 12 O'clock. Wires pointing down at 6. (must be adjoining ) and that 2 should be enough but not more than 3.

I thought ...sure...:rolleyes:

 

Since I wasn't using them...wth.

 

Presto.

 

Either the M-Audio will have these open by default of folks better be ready to get their mini phillips screwdrivers out.

 

 

 

JVC 55

 

no screws...utter **** and one hole

 

JVC 77 (Hammer gods)

 

 zero holes:blink: 

 

If I had opened the 77's 1st I never would have believed it... and I would not have opened the Akai.....there are no holes around that hammer.

 

 

To actually open the 55's and 77's is to see these are not alike at all. The 77's are massive 57mm and look even bigger. The magnet was so strong it sucked the screw out of my hand and pulled it into the cone with a slam. I though I ****ed the driver but I tested it and it's fine. The 55's are craptastic screwless  3 unit puzzles.:(

Well usually the holes are placed on the very back of the driver and as u can see the JVC 55 have 4 of them and 77 have 2. Those have the same affect if not more effective when it's placed on the back of the driver itself. 

I wouldn't suggest you do try that on these AKAIs though as the hole looks way too large, it's usually more like 1.5mm diameter holes other headphones use (Philips states for example "optimally configured driver port airflow for increased bass response" or something like that with whole that isn't covered with any sticker unlike on the AKAI here).

EDIT: Congrats on the McGyver entry-lvl skills! I bet now that you've experienced what a little bit modding can do you might be more curious to try something in the future too. :P

People turn even the open-back Grado headphones into "basshead" stuff by simply removing the tape masking the round driver hole in the middle.

Yup...my DD's had large bore holes in em'

 

Goes from the yoke to the cap. That's for the voicecoil more than venting. The open sides vent. Massive surface area needs all that open area or the surrounds would rip off

 

 

I'm pretty smart about bass...been doing it for 15 years.;)

 

Headphones are different but it's still a dynamic driver. 

 

 

The 55's have 4 bore +1 diaphram vent (5)  +2 cup ports  >>>over aired muddy bass

The 77's have 2  bore +0 diaphram vents (2)  +2 cup ports >>>tighter harder bass distorted by plastic frame before driver distortion

 

 The Akai have 1 (1)  bore and a flat response. no diaphram vents.

 

If i had not received the mail I would not have touched the Akai.

 

That's my Akai bro. Now it has the bass it was said it would have. Harder than the Q40 and sms dj pro (both 40mm)  The Akai is 50mm and now it hits harder than the sms but less than the 77's and sz's but has great mids and highs which seem untouched. Not perceiving it anyway. 

 

The JVC math would have prevented me from opening the Akai. It doesn't reflect what is true with massive subs. But I did it first and it was a profound difference. I will not open a 3rd hole since I have 2 hammers already.

 

I opened the JVC after and discovered the amazingly crap quality of the 55's  That's why they sound like crap. they are cheap drivers with too much bore through. I might try to cover that hole or combination of some but I already removed the pads so they are useless.

post #10687 of 11259

random question.

 

How does this song sound with the th600?

 

Do the vocals come through clear

post #10688 of 11259

So i went and saw excision last night and it was pretty insane, 150000 watts of bass in an indoor venue, it was pretty crazy.

post #10689 of 11259

Nice track, sounds good on the Signature Dj, and yes the vocals come clear.

I got an e-mail asking if I had considered reviewing my Akai cans. I responded that I had no experience with Studio Cans.

Got a 2nd mail advising that 1-3 holes (not more than 3) could be opened. Was told which ones to open in what order.

I never opened a can before so I proceeded with caution.  Remover 2 as I was told that would be enough without interfering with the lower mid and remaining response.

At this stage they hit about as hard as the Q40. The mids are spectacular. I actually have very little experience with mids. These cans are suddenly my 3rd hardest hitting which was the SMS Dj Pro...which also has a M100 type slope. "Fun".
These are now another can.
I will not open a 3rd hole.
I will do a review of these soon now.
huh... That easy? Lol. What would happen if a third hole was opened?

they are quite crappy un eq'd, and when eq'd still don't match up to the k240's, but they still hit quite well imo. I don't know how to take apart cans without damaging things, so for me to want to take that chance id like you to mess around with the ports to see what happens, if you could. smily_headphones1.gif id appreciate it. Tell me how it effects sound and slam.

If you pull the arm hinges out one at a time the cups will separate. There are no screws. It' easy eeeasy.

I would NOT recommend doing any modding unless you cover holes (example: cover 1 of the 4 bore holes on the driver and leave the diaphram hole open. May tighten? )

 I can take pics if you'd like later

maybe. I'll have to see. My friend borrowed my 55's for the weekend. Better than his applebuds I guess. I wonder what would happen if I covered up the diaphragm hole, and two of the driver holes like the 77's... Maybe bring out the highs and tighten bass? The drivers might be tuned similarly(hopefully), but maybe its just the ports (and the magnets, build, etc change the sq?) that change the sound signature?...

Well, either way I really have nothing to lose from modding them. They're under warranty from walmart, and if I break something, I could bring them in and say they randomly stopped working... biggrin.gif

First cans I've seen that actually market themselves as being basshead cans IN CAPITAL LETTERS!!! http://www.amazon.com/gp/aw/d/B004ZZR5Y0/ref=mp_s_a_1_39?qid=1396753947&sr=8-39&pi=SL75
