(RE: Your earlier post) Most of the evidence of high frequency hearing loss is based on hearing tests using pure tones. I'm not sure this is totally reliable, for two reasons. First, because it may be easier to hear the effect of high frequencies mixed with other sound than it is to hear pure tones. Second, because if the 18K region, for example, is attenuated 30Db instead of being totally gone, it could be missed on a hearing test but still have an effect on the perception of soundstage.

As far as the range of the transducers versus the placement of the drivers: both are essential for reproduction of high frequencies, and therefore soundstage. The high frequency region is very directional, so a badly placed driver could cause those frequencies to be muffled, while on the other hand the transducer has to produce them in the first place.

Mostly what you lose over 15K is soundstage, "air", and "space". 18K is especially critical for the height/depth part of soundstage.

That said, most people over about 35 can't hear test tones over 16K. But I still believe that if those frequencies are missing, most well trained ears can hear the loss of soundstage and air.

So, IMO, frequencies up to 20K are essential for sound quality, especially when it comes to soundstage. This could be one of the reasons that full size cans with a wider frequency range sound "bigger".
This post might date me , but this is a point that I agree with. Interestingly, Harmon Kardon was one of the early pioneers of the square wave mantra, emphasizing bandwidth in their pre/amp designs that were flat to well beyond 100K. (Many audio magazines still highlight amplifier performance using this metric.) The premise was that what we can't hear--especially in the upper regions--impacted the overall tonality and harmonic structure of the amplifier reproducing frequencies within our primary range of hearing. I don't want to get into the square wave revolution too much, but in the ES3X Appreciation thread, I submitted a post that described this point. Here's an excerpt from that post that supports barleyguy's premise:

"As an interesting aside, in the 70's JBL released a recording that demonstrated the impact of filtering the highest frequencies and its effect on the lower registers. Using a solo violin, they filtered the highest frequencies starting at 18K, 15K, 12K, and so on. The basic character of the violin was always apparent, but the instrument became more box-like, more basic in its fundamentals as the highest frequencies were filtered. The "air" and sense of effortlessness was lost. I could easily determine when each successive filter was applied, always preferring the unfettered and free sound of an unfiltered violin."

Does anybody know if JH will be providing a F.A.Q. of some sort, or a more detailed description page for each product?

Have you looked at his website? There's info re each model there. What else would you want?

Here's a snippet of the email I sent Brittany:

"I have a few questions about the differences between the 13 and 11. I noticed the frequency differences between the two, and I’m wondering, why does the 11 have a wider frequency range? What exactly allows the 11 to dip into the <20Hz region? Will there possibly be a model that will have the combined frequency range of the two (10Hz – 20kHz)? Also, are the cables detachable for any / all of the models?"

If anybody has any additional info, I'd greatly appreciate it

edit: I understand that some of my questions have been answered elsewhere in this forum, I just wanted to see if anybody had a more "official" source, rather than hearsay and whatnot.

Anyway man you are really crazy 2 customs for two thousand dollars it is not normal ..

contact him about any interests I don't believe they have a color list yet but you can get any color that UE has if not more. What I did was ask if he could make a nice deep blue and went from there.

Brittany mentioned to me to just specify a colour.. which is rather vague since they can't possibly do ALL colours... can they?

In any case, I emailed asking specically if stuff like Translucent Deep Red from the UE site would be available and if the cable length/colour is also selectable. We shall see.

Hey thanks for your explanation.

they mix for the colors so theoretically yes they can get many more colors then you would think so I would just pick one like you did and ask if it could be done

Ok, here's one option I've been thinking of. I'm a runner so I love this insignia! What do you guys think?

I like it. I wonder how the yellow would look against blue?

if you want to get a jist for mine the artwork is going to be my avatar and the color of the shell is going to be a deep true blue similar to the one UE has but not quite. The yellow is a good color to pop off the blue.

neutral or colored?

I have the ue11pro and found them too bass heavy. So much so that I have to put the bass reducer on my iphone or with my mac book pro and pico amp/dac. I regretted that I didn't purchase the ue10pro.
Now is this JH13pro more like the ue11pro (colored and bass heavy) or like the ue10pro (more neutral and flat)?

was this question brought up at canjam with jerry harvey or here?

thanks
