Yeah, but it acts like a normal dual driver - reduced vibrations but less sound distorsions since it has two separate sound outputs

According to Sam, and with my personal experience just looking at the frequency chart the large bump in the upper mids isn't going to sound harsh. The sound signature is kept the same, meaning a warm and smooth sounding signature. As long as the signature isn't too bright (which it isn't) the large peak isn't going to sound harsh.

The TF18X3 will go lower than 20Hz and higher than 15kHz. On Sam's tests, which is limited to 20-20, both monitors maxed out in the lows and nearly touch or touched the 20k mark. . The reason is because both monitors go lower than 20Hz (the DTEC and the TF10 low can both easily go below 20Hz with a output of 115dB), and the highs are around 20Hz. The TF18X3 should go lower than the SE530 a tad as Sonion drivers tend to have a more satisfying and responsive low-end. That is why the close estimates for the SE6X3 is about 18Hz-20kHz while it's 10Hz-20kHz for the TF18X3.

Not really going to make a difference. Both drivers share the same bore, meaning that sounds mix as soon as it passes the soundport of the BA drivers. That's about 1mm of difference. The downside of having dual soundports is that you must first insert a small piece of tubing/casing which joins the two soundports to the soundbore. Meaning it adds more volume, and more work to making the monitors.

omg unfortynately I recieved this info:
"Hi peter,
Sorry to reply you late.your package has arrived .but we cannot provide the service according to you design unless you pay extra cost.it cost about usd 200(resell and shipping back is not include)"
I wonder what's wrong with my design. It looks like they want to add drivers, which I don't want. I want to keep costs down. Come on! These are W3 drivers, why they can't?!

"Hi peter,
We only remolding the products according to our technical standard
Parameter.hope you can understand that.please tell us what potion you choose.we offer you favorable price usd 200 for your design by yourself.we also design new products to custom by others requirement ,it cost usd usd usd 600."
That's not fair... they said 90 buck now its 200! or 600... Great.

I fully agree with MaoDi.
How can the perfect transmitter be developed without knowing all imperfections of the receiver? In other words, how can one develop the perfect sound system without a study of the human ears characteristics? We invite you to do a small experiment; play a wellknown and high quality music track at a sound level of about 80dB. Play it a few times, listen critically, and adjust your tone controls for best sound quality and tone balance. Now boost the volume to about 100dB (make sure that you don't exceed the limits of your system) You will notice a change of tone balance, and you will be tempted to make small changes in your tone settings...

Now what is causing this phenomenon?

The answer lies in human ears imperfections. Off cause, the human hearing curve can be measured and plotted. This is normally done at reasonable low levels, for example to check for the need of wearing hearing devices. But when we repeat these measurements at higher sound levels, and plot the lines of equal loudness, we will see that higher sound levels produce a different curve. In 1933(!) the first scientific research in this field was done by Mr. Fletcher and Mr. Munson. In 1937 they mapped the hearing curves over a wide area of sound levels. Although more recent research produced slightly different curves, and some assumptions had to be re-adjusted, these scientists really produced good data and a solid base for future research. Therefore we would like to credit these guys by using their names for this phenomenon. In 1956 two other researchers, Mr. Robinson and Mr. Dadson mapped slightly different curves thanks to their more accurate equipment. The Robinson Dadson curves are therefore accepted and adapted by the International Standards Organisation as the basis for ISO 226:187; Normal Equal-Loudness Level Contours. (ELCC)

Conclusion so far:

Our human ear is far from linear, dynamically speaking, especially in the low frequency and high-mid frequency regions.

Grazie Mile
I saw something similar at Etymotic website. From what I noticed when I use my PFE's I like to listen it at 24/50 on my D2. At this particular volume LF sound really good, but when I listen at 15/50 they lack LF.

Now here's a little bit of update from the UM:
Remolding service: $159 shipping ww included
Own design: $200 + $159 shipped
ES3x or other brand design: $359 shipped
UM special desing: $600 not sure if remolding service is included in price

Giuseppe, I'd love to try our gatherd forces in my Sonion designs, are you interested? Se voglia, spedisci mi un PM

Welcome to 6 driver fantasy. Purple is TF-18 Pro, Blue is SE6X3.

TF-18 Pro (6 driver TF10)





SE6X3 (6 Driver Se530)

Me want sound impressions! these are beuties!
These 6 drivers barely fit the shell. I can't wait for my customs

Have I said before light blue' are amazing ?

They are amazingly built. Once again, top quality from UM. There's actually still quite a bit of room in there. But yes, my ears are smaller (hey what do you expect for my age), so the drivers do seem to "fill up? the space a bit.

Just gonna give them a quick burn in, just to let everything fall together better. Lots of new stuff in. Impressions will be up pretty soon. So far though, quick listen. My words are "Bring it on UE and JH, i'm sure my 6's can stand up to your 6's. "

Big words in fact

If you got to listen, i'm sure you would say the same

http://www.head-fi.org/forums/f103/d...a-here-466222/ this is something related to our thread, it might help.

interesting. I would use something that's stiff rather than silicone for the mold. Something like ultra glue or something. Coat the impression in shortening, and mold away. Then later fix in the tubing, and fill it up with silicone. I think it would be a much cleaner job. But hey, who knows. No one's tried it yet.

Ok so to start off. Both monitors are really really fast. They easily outclass all my monitors in terms of speed. Running them with a high-end source, the soundstage for both is wide wide wide and tall tall. It just sounds like you're sitting in a reference room with speakers surrounding you.

The TF18 first. Using the UE700 driver as the highs (i'm sure the TWFK will sound just as nice), the highs are crystal clear, with a fantastic tone to it. It's no longer the irritating high frequencies that many people find in UE, really crisp, clean high frequency response with lots of detail. The decay is just perfect as cymbals fade out absolutely perfectly. Mid-range...yup you probably guessed it that giant chunk is finally filled in. All i can say is, basically the mids are what the JH10X3 has, but more refined, quicker, with better accuracy. Wonder if this is what the JH13 sounds like? Lows are deep (deeper than the UE11), quick and punchy. The signature is still like the TF10, but it's much quicker, with a quicker and more powerful impact.

Overall, the TF18 is less than neutral, and offers a perfect sound for audiophile listeners, and touring artists.

The SE6X#, what can i say but it sounds like a Se530 on Steroids. To begin with, the really warm sound signature is slightly brightened up to offer a overall crisper and cleaner sound signature. Highs are now dominated with a TWFK driver (ok fine, i cheated i got a proprietary driver here as well. But like the UE700, this proprietary is also a TWFK alternate). So all the highs you want is now in the SE530, the highs aren't as dominant in the SE6X3 compared to the TF-18, but think of a Mage, turn down the brightness a little. That is what you are getting, plus more details, and more refinement. Mid-range is basically the SE530s but quicker, and cleaner. (on the frequency chart, the mid-range is actually put even closer than the stcok SE530, but because there's more highs and lows now, it evens it out) Lows...haha. Nope it's not that warm, messy stuff that many of you think the SE530 has anymore. The dual low drivers will brings the frequency response down to 10Hz (got them checked out at a local audio equipment store...but hey most of us can't hear it to 10Hz anyways. I can, but i only know that cause of a hearing test.) Impact, Punch, Decay, Tone are all very well defined in the lows of the SE6X3. It may not be as powerful as the TF18, but it's more controlled and has a faster decay so the punch is more like a ninja jumping out and punching you then running away rather than buff picking you up and punching you in the gut (ok that's probably one of the worst similes ever).

The SE6X3 if very fun to listen to, but this is a far more suitable monitor for studio recording, sound engineers, and on-stage monitorng for vocalists, and guitarist.

nice review maodi..
its good to hear that all of them sound better than the original..
so all of them sound better than ue11?

is there any news about w3 remould+3 driver?

thanx
