Interesting.... I'm trying to figure out my next set. The DK3001 pro was on my "list" whereas the fh5 want really on my radar besides knowing of it's existence, as fh7 is more comparable).
Seems strange the 10mm polymer driver in the fh5 can keep up with the 13 mm bery in the 3001....

You used any Eq to compensate? In theory the 13 mm bery should go lower and be more powerful....

From the reviews that I read, the target sound signature for both the Fiio FH7 and the Dunu DK-3001 are "mature", when compared to their respective siblings (FH5 and DK-2001). The FH5 and the DK-2001 are considered to be the "fun" solution. Unfortunately I won't be getting the DK-2001, as planned, vendor related issue.

I used the same EQ settings for both the FH5 & the DK-3001

Driver size and coating material do not necessarily influence the tonal balance, or "tuning" of an earphone. Each company has its own acoustic design goals, and the 13 mm driver size was chosen to improve z-axis movement of the driver. The diaphragm surround and dome are formed in one single piece, we choose what proportion of surface area is used for the dome portion and what proportion is reserved for the surround.

​

This is a close-up of an engineering prototype of the previous (now completely redesigned) version of our upcoming ZEN model. The new ZEN has a completely different driver, so this isn't it, but this old prototype version uses a 13 mm dynamic driver very similar in appearance to the dynamic driver in the DK-3001 PRO (just different a PVD thickness and texture for the beryllium coating). This transparent ZEN prototype is used to approximately represent the driver inside the DK-3001 PRO. You'll notice the serrated edges (the surround) form a substantial proportion of the driver. This means the central dome portion is able to move in and out in a more optimized manner.

Frequency response is not only the driver itself, however. It is dependent upon the housing chamber morphology, damping, and venting, with other minor factors as well. So being able to hear/feel sub-bass is not wholly dependent upon driver size and/or driver material. In fact, for the DK-3001 PRO, we chose not to overly emphasize sub-bass, focusing instead on an articulate, easy-to-listen-to experience. It would not be surprising at all for another company's product to have a different tuning that emphasizes instead other parts of the musical spectrum. If we chose to alter the venting and damping pattern of the DK-3001 PRO, it could end up sounding a lot different.

Yes, all that being said, is there a product in your line that emphasizes sub bass more and or would respond to EQ/DSP better? I've heard the dk 2001 has a more V shaped signature.... Which one is capable of the greatest bass output?

Question though, it seems somewhat strange to use such a large DD if the goal is not to create large bass quantity. Why not go with a smaller design that has an easier time with transient response? It seems to me a 13mm DD is counterproductive from this standpoint, and simply increases the production cost while not necessarily having benefits over a smaller driver if the intent isn't subbass and bass quantity....

πr^2 matters, it takes a much stronger magnet to control all that extra surface area.

The DK-2001’s FR response is pretty balanced, but varies with tip choice. I can get a notable V-shape if I want using Sedna tips but using the balanced tips, well balances things. I ended up using SS-sized Spin-fits (I normally use M) as I ended up with the most comfortable fit and a balanced FR response. The DK-2001 has, subjective, satisfying sub-bass.

I don’t think any reviewer has said the 2001 is V-shaped in FR. It also is up to interpretation what defines V-shape vs. mild dip.

From @davidmolliere:

“The DK-2001 is neither U nor V shaped but rather features a very balanced and smooth signature with a great deal of fun in all the right places.”

https://www.head-fi.org/showcase/dunu-dk-2001.24085/reviews

The Dunu 480 has quite a notable sub-bass emphasis (beyond the DK-2001’s sub-bass amount given equal volume) and an overall U-shaped FR. At least that has been my experience.

The model with the most sub-bass boost in our lineup, currently, is the DM-480. The DK-2001 would be the next step up where there is more emphasis on sub-bass than mid-bass. However, the model that would provide the best overall sub-bass experience would be the DK-4001. The spiral pathway of the ACIS system induces a very specific backload on the driver that boosts frequencies under 80 Hz without losing texture. LUNA provides the most overall bass resolution, with better delineation of bass instruments, but its sub-bass quantity is not as prominent relative to the DK-4001.

Large size dynamic drivers have rarely been used in search of more bass when it comes to headphones and earphones, because they're coupled to the ear. This paradigm really only applies to speakers, because they're coupled to the entire listening room. For earphones, there have been companies that have released 16 mm driver in-ears with flat bass shelves, and other companies with 3 mm drivers that have bass shelves that rise, even all the way down to 20 Hz. As mentioned in the previous post, the size of a DD is both its dome and surround, but only the dome is responsible for sound reproduction. The surround is there to allow the dome to vibrate as evenly as possible. So the design goals associated with choosing a large sized driver are myriad.

In the same vein, a smaller driver does not mean it is better with transient response. A smaller driver having a potentially faster transient response only means displaces less deeply, and does not inform us about control over the attached voice coil, nor the distortion. We can easily pair voice coil and magnet combinations that can control both large and small drivers very well; it's not a limiting factor. However, transient response is often also determined by the stiffness of the driver dome, as well as better internal damping (lack of ringing). This would mean that driver material does play a part in transient response (pure beryllium metal or pure CVD diamond are best, with beryllium being the better choice in headphone and earphone applications because of mass considerations).

Thank you for the info on your products line, it is helpful.

But I do have one bone to pick, quoted above.


Oh come on now. That first statement is objectively false, it's advertised in IEMs as well as over the ear sets even on planar sets. Simple math (πr^2). It's not a coincidence that the biggest basshead sets are large diameter DDs. Sony ex800st is a 16mm DD. IMR uses a 15mm bery. You're own products market the large DD as an obvious benefit. All other things being equal, a larger diaphragm provides more displacement and it absolutely IS something headphone makers, including DUNU, consider. Yes, there are a lot of other factors, but all things being equal, a larger diaphragm is sought after in headphones.

You do have me concerned now about something I never really considered though....

Basically manufacturers can make a bigger surround and use the size PURELY as marketing....

It would not be evident like it is with car audio that they're pulling a fast one by doing this. Looking at the pictures though, one that springs to mind is the Jade EA3/fiio fh1s....

Ughhh, now I have to look really closely at pictures of the drivers of all sets to see how much I'm being lied to....

The point is to bring light to the fact that while there is a benefit to a larger diameter dynamic driver, it is not there for increased bass response. It is there for improved bass response. In previous posts your concern was always about the quantity of bass. If it's about quantity of bass, pretty much any size diaphragm will do.

"Lied to" is a strong statement. While manufacturers can make drivers with larger surrounds for the sake of bragging rights, most do not. There is still an ideal ratio between the dome and surround that most manufacturers adhere to for mass, flexibility, and distortion considerations.

You've got me on the semantics. But my point is that headphones/IEMs that move more air are perceived by me as having a greater quantity of bass and more realism. I don't think that's something you can probably graph, but it's a big difference why I prefer DD bass to planar or BA bass. Bigger isn't always better in these ways, but it usually is, as a rule of thumb. Certainly there are exceptions....

I'll try to find it, but back when I lived with my friend who owned a car audio business, he did an install of a 15 inch sub for one of his regulars. The surround on that thing had to have been at least 3-4 inches on each side.... It sounded absolutely awful too, just boom boom boom. This was 20 years ago or so, but that was an egregious use of a rubber surround.

It even looks sexy. When will it be available?

The DTC-100 is now available standalone! It took us a while, and we were waffling because we were trying to determine whether we should keep it as a LUNA-exclusive or not. But popular demand prevailed, and we're now making it available for sale.

The announcement was just made here:

Hi, I'm interested in Dunu DK-3001 Pro. Does anyone know if there is a discount for the forum members at the moment? Thank you.

Muy contento con ellos. Son muy cómodos, el cable es increíble. Aunque me gustaría que los agudos sean más altos.


[/ CITAR] Hello, greetings from Spain. How about the treble findings? I am a lover of extended treble ... how about the Ibasso dx-160 ?. I would use them in LgV30 and Pro-ject pre box s2.

 

[MatusSVK]

I have a bit of a dilemma. I can get the Dunu Dk-4001 for £500 and I'm wondering if it's worth going for that over the dk-3001 Pro (for £350)?

 

[feverfive]

I've been doing a lot of research the past couple weeks for a mid-priced IEM to be purchased around Black Friday this year. I'm a little surprised the 3001 Pros haven;t gotten more burn. Based on the little that's out there, sound attributes aside, I like that build quality does not seem to be an issue. I despise dealing with stuff that is constantly down due to poor build.

I have received the Dunu Dk-3001 pro and am delighted with them. I need more tips of the type (red vocals and premium dunu). How can I buy more?. I searched the internet but I haven't found a way.
