now announcing........THE NEW!!!!!!! MUCH IMPROOOOOVVVVVEEEEDDDD~~~~~!

Feastrex.com

Please visit this new site.

I did... You could lose the Flash (it ruins the picture experience -- i won't be going back there)... and the javascript menus are hokey), but nice to have the information.

Now that you are in the US are you going to be able to get an answer to my question, these 2k each paper weights could be put to much better use.

New web site

Clark,

Thanks for the update on the website. I took a click-tour thru it and have noticed that one of the tinyurl links is broken. While they make url links short, they are not always 100% accurate, i.e., there.

I would consider most of the site high-level information and marketing hype, not anything that technical or useful for the DIY crowd. There are no specifications listed for any of the drivers (even the old site had some specs) and no references to recommended enclosures or any pictures of completed speakers. Having a PDF spec sheet download for each of the drivers would be valuable. It would also be nice to have some PDF downloads for recommended enclosures and some links to existing enclosures like the Freddie Chang BVR that people are using.

Sorry to rain on the site, but I don't really consider it (technically) useful and there is not much there to actually entice me to buy anything (and I already own a pair of D5nf which I love).

Also, as you're back in the states... does this mean you're not going back to Japan to continue working with Feastrex??

Regards, KM
 
Great pics and succinct commentary from Audio Federation

Attention folks at Audio Federation: I sure don't "hate you" (or anyone) for not liking my favorite speakers. Great pics and succinct commentary:

Maxxhorn, conclusion on the sound: negative
http://www.audiofederation.com/hifiing/2008/RMAF2008/report/1500/floor_10/#maxxhorn
My comment, without having been there: I suspect there might be a benefit in using different electronics -- somewhere in the signal chain (or perhaps at multiple places in the signal chain) there may be weaknesses, and if they are there, the Feastrex drivers will expose them mercilessly. That is one reason why Mr. Teramoto went over his electronics with a fine-tooth comb during the past year and brought in all his own electronics for the 5-inch urushi cabinet speaker for this RMAF. (I am also reading a lot of very positive reports about the Maxxhorns at RMAF, by the way.)

Feastrex 9-inch drivers, conclusion on the sound: negative
http://www.audiofederation.com/hifiing/2008/RMAF2008/report/1500/floor_9/#lotus_2
My comment, without having been there: Can't blame this on the electronics, obviously! (The electronics were excellent.) Mr. Teramoto tells me that this is the best motor he has ever built. As a motor, it absolutely rocks. (According to Mr. Teramoto.) However, he feels the need to modify the moving parts to accommodate the new motor in order to get the best performance out of it. One other, and possibly much more important reason, is that Mr. Teramoto devoted far more time to proper setup of the 5-inch drivers in the next room than he did to setup of the 9-inch drivers. (This was the overseas debut of his friend Mr. Tanaka, the urushi craftsman who built the enclosures for the 5-inch drivers, and he wanted to be sure it was a complete success.)

Feastrex 5-inch drivers, conclusion on the sound: extremely positive
http://www.audiofederation.com/hifiing/2008/RMAF2008/report/1500/floor_9/#lotus_1
My comment, without having been there: The driver and enclosure were of course excellent, but part of the reason this sounded so good was probably the electronics. When you get into speakers that are as revealing as these, you need to be prepared to re-examine your entire system. Any weaknesses or mismatches in the upstream sound chain will come through. Use these with inferior or improperly matched electronics and the outcome will likely be different . . .

Just my two cents from the peanut gallery, to be taken with a grain of salt since I was not there.

Because they fall into quite a common Japanese philosophy whereby technical design is dismissed / almost irrelevant.

Hand on heart, I really do wish them well. We need driver manufactuers, and the effort that goes into these monsters would deeply impress even the most jaded cynic. Chris is certainly doing his best to advertise them, but there's nothing technical of use in his posts, bar the two sets of measurements he managed (thank goodness) to take a goodly while back for the D5/9nf. Same goes for the site Clark put together for them. It's all very nice, but there isn't actually anything there that could be used to design a cabinet for them.

To remind anyone from Feastrex who might read this: outside of Japan, the majority of people do not build cabinets by guesswork, and when they've shelled out x thousand $ / £, they are rarely inclined to build multiple prototypes. If you are actually serious about selling to the DIY market, you need to listen to what people are asking.

I am quite interested why Feastrex does not publish technical data. Surely they can give people some idea how good speakers can be designed from the data.

1) As a business, Feastrex is still not in the black, although it is moving in that direction. The president of Feastrex is not willing to pay someone in Japan to do such measurements for them. (Admittedly, in Japan, such measurements are expensive.)

2) Feastrex did purchase from the USA a loudspeaker measurement system but they have been having difficulty using it, due to their inability to communicate effectively with the maker of the measurement system in English. The work on Feastrex drivers that takes place inside Feastrex proper is all done by just one person, Mr. Teramoto, and he finds it hard to make time to try to figure it out.

3) For a time Clark Blumenstein was working on it, but nothing seems to have come to fruition (as far as measurement of technical data is concerned) from that. At the present time there is nobody inside Feastrex full time who can speak English. Feastrex does have some bilingual part-time staff, but I have my doubts that much progress will be made here soon.

4) On the one hand it is too bad that Feastrex is on a different wavelength from that of many DIYers who place great emphasis on T/S parameters and other measurements, and obviously they are losing some potential business as a result. On the other hand, there are several enclosure designs that have been demonstrated to work well and which are available to DIYers.

My personal feeling is also that they would ultimately come out ahead financially, through increased sales, if they would either pay some company to take the measurements for them, or hire someone to figure out how to use the system they already own and instruct them on what they need to do. (I would do it, and could do it, if they would pay me, but I'm not going to do it for free and I doubt their president would feel the cost is justifiable.)

-- Chris
 
1) Then, bluntly, he doesn't understand the market. I don't blame you for not doing it for free either Chris. Why on Earth should you?

2 & 3) As excuses go, it's not an especially good one. WT2/3 isn't all that difficult & if you're going to get involved in the international market, logic says you need to have someone who can communicate on board. Couple of hours with an English speaking friend or interpreter should get the basics done. If that's an unjustifiable extra expense, they need to reexamine their priorities ASAP. Like, yesterday.

4) Indeed. WRT the existing cabinet designs, who knows, but not everyone wants a BR, or something voiced in that way. What works well in Japan does not always go down as well elsewhere.

Many of us actually want to support Feastrex -small companies should be encouraged. But they're not helping themselves in this matter.
 
Chris,

Thanks for the insight on this.... your posts and passion for the Feastrex drivers is a main factor that led to my purchase of the D5nf drivers last year and is a purchase I've not regretted.

However, points from others (including myself) still echo about, regarding the lack of technical information. As the majority of their drivers appear to end up in the DIY community (do correct me if this is not the case) it would seem prudent to have more meaningful information available.

Shortly after receiving the D5nf drivers, I had some contact with S&L and purchased a WT2 for testing the D5nf and some of the other drivers in my collection. I did not find it difficult to use in the least and I swapped a couple emails with Greg Larson which was also very informative. Still, everything is in English (info and software) so not having the ability to understand English makes this a real problem.

I agree that Feastrex would likely increase their sales by having some complete information available. I would also be inclined to focus on the D5nf as it is the most affordable driver and would be within the grasp of more DIYers. Having a better support structure behind these would help lure some additional sales.

On the way... We have been slammed in the shop trying to get things out before friday this week. your answer is on the way tomorrow.

We were thinking of going flash for the tabs, but left it Java so that they would load faster and that we could bring the site to the public faster. We could later add the flash tabs if the proletariate Java hurts your soul so bad...

Regards, KM

Points taken. I do not have any new specs for the drivers. If necessary, I will put on the old specs. PDF spec sheets? That is a good idea. I will likely need to delegate it though.

Recomended boxes. We could work on this.

In general: technical information: Please inquire directly. I will put in a clause like this. We are to add technical stuff later, and it will be slightly buried so as not to confuse the general site visitor. I and my web designer were contracted to build this site for Feastrex. Consider it to be the basic form upon which more information, better photos, etc will be added to. This site is now a team effort, I should add. You are part of the team... So thanks for the suggestions!

Despite the initial gripes, I hope that everyone can agree that it is a better basic format to receive and read information from...? Please use your imagination...it will become more fleshed out in the coming weeks and months.

Returning to Japan? I will be my own spokesperson here: We could all agree that this is eventually the plan that we are working towards. We left efverything on an incredibly high note, all of us realizing the surprising value of our collaboration. Mr. Teramoto sent me home with the pair of NF5ex that he had me personally build. WOW! When will I go back? Up in the air. We all need to save up the requisite time, money, and energy again to make it happen. It might be a ~few years from now.

My own business in the states is modeled such that I could leave the designs to be built by Jason Flanary (lovecraftdesigns.com) temporarily if I were to leave for an apprenticeship again.

Lets just say that in my time here, I am an apprentice to Jason for fine woodworking - the flipside of drivermaking... In Mr. Teramoto's POV, it all goes together. So he gave me a mission to learn even more about box design before I should come back to learn even more about drivers. Frankly, I agree with that method of learning. cross training. They are excited to have me design Feastrex oriented boxes for the American market. In my recent speaker designs, there is alot of reflection of what I have learned while in Japan. Very fun stuff. So think of my apprenticeships as learning woodworking/speaker design (from Terry Cain, self taught basic woodworking as initial phase of BUF and senior project building a clavichord, learning Driver making and design from Feastrex, and now back to cabinet design and fine woodworking in conjunction with driver making/modifying at BUF/lovecraft/cain and cain. The next stage would logically be high level driver making. That will be in a while, I suppose. I am only concentrating on today, which is now tomorrow

In light of that, good night. Truely guys, thank you for the suggestions. I will do my best in the time I have.

-Clark
 
I adore anything FR , but ......

taking in account that Feastrex have decent advertising praxis ( either with showing on audio fairs or via more or less official representatives on audio forums ) , not bringing enough technical data about their own products can't be nothing else than neglecting potential customers.

you can't pull anyone to sleeves , asking his attention ( and - finally - money) , refusing to reveal what's that what you are selling ......

expensive third party measuring , language barrier ...... that are Feastrex's problems , absolutely inexcusable passing that to customers

for example - I'm absolutely capable to make my own measurement , in case of some ancient driver ; but - I'm absolutely sure that I'm not willing to do that in case of something fresh , and - honestly and fully paid .

that issue about T/S data , at least here on DiyA - is becoming shameful to Feastrex .

it's time to - either - Feastrex do own homework regarding T/S (ie. duty to customers) , or to stop bombing with organized advertising ;

or - just move to "Vendor's Bazaar" , at last .......

there are independent measurements of some feastrex drivers. apparently there are strong reasons such a data is not published and those who measured it prefer to mind their own business.
I also have some measurements of drivers designed by Ted Jordan in the past, some of which I would not publish without his concent. So I fully understand. But even Ted publishes enough data for basic design groundwork.

I can also understand that nobody would want wine to be analyzed in such a way so that people can decide whether to get it or not without tasting it.

I somehow agree that if no more data can be provided, probably the "Vendor's Bazzar" is a good place.

yup ;

regarding the

I can also understand that nobody would want wine to be analyzed in such a way so that people can decide whether to get it or not without tasting it.

I couldn't agree more ;

but - in that case entire situation (here - in non comercial part of forum) is plain wrong ;

any satisfied customer - DIY-er , is without any doubts completely entitled to write odes about his own satisfaction with any product , including Feastrex ;

on the other hand - Feastrex have all rights for own policy and own rules , regarding data and knowledge sharing and attitude to own products ;
and they can represent own products as great wine , which quality can be only sensed , not measured ;
but - for my sense of honesty - that can be only in Trading part of forum , not here .

if they need and want DIY crowd attention by these prices - (I repeat : here - in non commercial part of forum ), they must follow DIY rules - give me data to dream with .......... then I can decide am I rich enough .

soongsc, thanks for your comments, and for your very wise observation.

I just wanted to let everyone know that I translated all the comments from soongsc-1 to soongsc-2 and emailed them to the president of Feastrex. If you open your window and listen you may year the sound of his head striking the ground with his repeated kowtowing and asking for forgiveness. His attitude is one of asking how high he needs to jump while on the way up. He wants me to assure everyone that he will get the data out one way or another ASAP, and although it does not justify the long delay he wants everyone to understand (and I think you all do) that while they sincerely hoped everything would be properly taken care of before Clark's visa expired, things that they could not have easily anticipated made it impossible to take care of that as promised. That plus the mad rush to get ready for RMAF kept them from delivering on the promise. Now having just returned from RMAF there is a backload of stuff to get cleared out of the way but he now well appreciates the situation and is determined to give this high priority. So please be patient for a little longer, if you don't mind . . .

-- Chris

P.S. I also got this apology from Hal Teramoto:
"Please accept my apologies . . . I will try to get the D5nf, D9nf and the NF5ex -- which I assume are the main units of interest to DIYers -- measured ASAP, and then we'll be happy to email that information to anyone who enquires. (There is an email link at the website.) Please understand that I have never had any use for T/S parameters, don't understand them, and wouldn't know what to do with them, and all I can do is ask your forgiveness of my ignorance on such matters. I can well appreciate that this information might be extremely important to a lot of people and we'll do our best to see that the situation is rectified ASAP."

Let's get one thing clear here -- Hal Teramoto has posted in diyAudio exactlly one time, I believe. If you include Clark Blumenstein's posts during the three months he was at Feastrex, perhaps there are a dozen posts from people who could be called Feastrex employees, and many if not most of Clark's small number of posts were in response to people making inquiries that were appropriate for Clark to respond to.

As for my relationship with Feastrex, I don't get even one penny in remuneration from them for any "services." Neither do I have any Feastrex products in my home. At one point I borrowed a pair of D5 drivers for a few months, and at another point I borrowed a pair of D5nf drivers for a few months. The last time I listened to any Feastrex product was over a year ago. I would like to have a pair of Feastrex drivers and maybe some day I will, but as a father with seven children to raise, including two attending music conservatories (which in Japan are not cheap), my wife is not about to let me use such expensive speakers. For well over a year we have been listening to all of our music through a boom box that cost less than $200. I do get a lot of live music around my house, but that's neither here nor there . . .

So, that being the case, I hope in the future I will be spared arrogant talk of consigning "Feastrex" to this part or that part of the forum. I'm not Feastrex, and Feastrex is not me. I was already told by the jerks at a certain "Audio Nut-House" that I need to register as a member of the audio industry if I wish to continue posting there. Needless to say, that idiocy on their part reduced my postings at that forum to close to zero. If that happens to me here, I would be more than happy to simply extend my middle finger to the entire audio community and shake the dust off my feet as I click on the "close window" button in the upper right hand corner and make my final exit. It's no skin off my teeth. I DON'T OWE ANYONE ANYTHING.

to each his own ;
as I wrote earlier - I just adore FR speakers , and just seeing pictures of Feastrex drivers was/is pleasure for me .

but - solely in matter of T/S data , and repetitive asking of DIY fellas for same , I made my comments .

so - no one answered positively on that matter ; all I ( and probably few others ) can read is (also) repetitive writing how Feastrex drivers are nice and gorgeous .

at least to my reasoning , boyz at Feastrex can't pay you enough , for all your neutral writing .

bring data , then continue with odes .
have at least that much respect to ppl to whom you are writing .
 
Chris,

I fully understand your position... and I for one am grateful for your persistence is helping to bring information and experiences about the Feastrex products to the audio community. As you clearly stated, you don't owe anyone anything. I would be more inclined to say that Feastrex, as a company, probably owes you a debt of gratitude and more for keeping this thread alive and acting as an intermediary between the DIY crowd and the company with end-user feedback (both positive and negative) and the simple fact that your efforts have resulted in product sales for them.

Regards, KM

PS - I think you've earned a pair of drivers... tell Hal.
