John, you've got the last pair of drivers. That means that all drivers have been spoken for. The order has been finalized and the payment for the drivers is pending. Subscribe to this thread if you want to keep on top of what's happening. The shipping option was changed to airmail so I should receive the drivers this month. When the time comes, I will email each of you individually regarding payment. To be fair, and to help me keep my sanity, I will do it a few people at a time and will go down the list in order of who posted first in this the thread.
Stay tuned for more :) |

Any news on the status? I am only wondering as it is becoming harder and harder to fend off my wife as she tries to spend the money I have earmarked for these. I guess I will just need to hide it under my side of the mattress.;)
Thanks for all the hard work. It is greatly appreciated. |

Since I keep getting emails from people making sure they're part of the group buy:
Everyone who has expressed interest in this thread or via email has a pair of drivers reserved.
The drivers should be in the US by now and the local delivery company should contact me soon to find out when they can drop them off. |
|
|
| BWRX |
| The drivers are in Philadelphia but are being held up by customs... This means I have to pay a storage fee on top of the customs fee of 5% of the value of the goods... Hopefully they will clear customs soon. |

As mentioned above, the drivers are in my possession and am about ready to start sending these things out.
I've tallied up all the expenses (I think) and here is the cost break down for everyone to see:
Drivers: $11000 (100x$110)
Shipping: $890 (Air + Ground freight)
Fees: $760 (5% cost of goods duty fee + brokerage fee + airline storage fee + wire transfer fee)
That adds up to $12,650 and when you divide it by 50 people you get the base price of $253 for a pair of drivers.
Shipping costs using the USPS flat rate boxes are as follows:
to the US: $9
to Canada: $25
International: $40
I haven't checked how much insurance would be or if it is even offered on shipments to Canada or international destinations, but if you would like it added I can look into it. I was hoping to be able to do delivery confirmation so I at least know they were delivered but that service isn't offered for international shipments.
EDIT: Here you can see how much insurance would cost - an extra $3.35 for shipments to Canada and $3.80 to all other countries. It also looks like I can do delivery confirmation for international shipments.
If you would like to pay with a check the total will be $253 plus the shipping cost. My bank told me to wait 7-10 days for checks to clear, so there will be a short waiting period before I ship if you pay by check. If you want to pay via Paypal and are in the US add 3% to the total cost. If you want to pay via Paypal and there is a currency conversion involved (Canada and international) add 4% to the total cost.
I will notify each of you via email (the one you have registered with the forum) regarding payment. As mentioned before, I will do a few people at a time and will go down the list in order of who spoke up first, so please be patient. |

I'm just a third party instigator; but in September, forum member Zaph (John Krutke)mentioned a interest in testing the Jx92S drivers. His testing is impressive and he has quite a library of test data that makes it easy to compare to other brands and models. Ref: www.zaphaudio.com
I have not been in contact with him and he is starting a "really big project", so I don't know if he can make the time. However it would be a win-win if one of the group buyers would lend him the pair of drivers for testing. Any takers? |
|
|
| BWRX |
| If he's really interested I would consider loaning him my pair for the sake of measurement. |

I also - but he'd have to go through the possibly additional hassle of shipping them to Canada when he was done.
Zaph? |

Zaph is not testing at the moment, but he as shown some interest and some concerns.

Brian,
Have you sent any Jordan's out yet? I haven't gotten an E-mail yet and was wondering if something has gone awry??
Thanks |
|
|
| hifiZen |
Wooohoo! Nice photos, and awesome job Brian!
Those boxes don't look as well padded inside as I had imagined they would be... I'm a bit nervous about shipping them wedged into a priority mail flat-rate box. Maybe I'm overly cautious, and I hate to complicate things for you, but I'd be happy to pay more to have them double-boxed with a good 2+ inches of extra padding.
Too bad about Zaph, I'd really like to see his measurements posted along side the other drivers on his site. Hopefully he'll be back at it some time soon. |

| Colin |
As an experienced user of the JX92, a word of caution: always protect the cones when working with these drivers - the smallest of screws can dent the delicate alloy if dropped on the cone. I recommend a circle of cardboard or similar, same diameter as the chassis, with cutouts for the mounting holes. The roll surround is convex so you won't be able to do more than hold the card lightly in place with masking tape or similar but that should be enough to prevent disasters.
The odd dint doesn't seem to harm the sound but is very annoying to see on a driver of this quality.
Good luck with the designs, chaps, and I look forward to seeing what designs appear on this thread. |

| BWRX |
| Sorry for the delay, I've only contacted a few people so far, but the hold up is because I was going to measure the drivers and "match" them up before sending them out. I'm having some complications with the software used to do this, and if I can't get some results with it this weekend I will just start packing up the drivers. |
|
|
| Bill F. |
No hurry here. Happy to wait an extra week or two for the matching.
Thx much.

| Ted Jordan has told me a couple of times that the JX92s have been on spec out of the box whenever he's tested them via his MLSSA system. If so, adjacent serial numbers should be good enough. |
|
|
| BWRX |
| quote: | Originally posted by Colin

That would be great except for the fact that there are no serial numbers anywhere on the box or the drivers :cannotbe:
Regardless, I'm beginning to measure them now that I've got a reasonable setup. The T/S parameters are a bit difficult to calculate accurately but even if my measurements aren't very accurate in absolute terms they should be reasonably precise. |
|
|
| billnchristy |
This will be great.
I planned on building a transmission line with the pair I already have, but these will allow me to do so with no musical interuption!!
Heres a pic of my tiny bookshelfs I built last year and the system that powers them |

| Nice Bill! Any details on the enclosure (a link to a thread on here perhaps)? |
|
|
| billnchristy |
I dont think I ever did a thread here.
They are just a tad bit bigger than the sealed enclosure Jordan recommends, I did 5.2l instead of 3l.
They are quite packed with stuffing.
I always use a sub with them (obviously) -3dB is around 90 or so, but they play the fundamentals of bass really well so everything stays centered.
I have compared them directly to $1500 ID speakers and they fare pretty well. Now with the tube-pre and mouse combo, they are incredible.
I cannot wait to try a more full range enclosure.
PS about the box, mine came from Hong Kong without too much extra packaging and arrived just fine. |

20 drivers were measured so far and their numbers are all very close to each other (Colin was right!), so I have decided that I will not measure any more of them (it really is time consuming) and will start sending them out. Sorry for the wait!
Here are the average values of the T/S parameters for the 20 drivers that were measured:
DCR 5.2 ohms
Fs 58.6107 Hz
Qms 1.0726
Qes 0.3645
Qts 0.2720
Vas 10.2355 L |

Well,it was a nice idea, but it sounds like a bit of a grueling task. I think it will be fine just shipping them as they come to hand.

| Interesting figures - I wonder how much break in alters them or whether there has been a change in manufacture. |
|
|
| BWRX |
I don't think break in will alter them that much and I don't think there has been a change in manufacturing either. The method that was used to measure and calculate the T/S parameters always seems to result in higher resonant frequencies compared to manufacturer's specifications. The method used was the one from Rod Elliot's pages http://www.sound.westhost.com/tsp.htm with some minor differences.
Edit: The minor differences are in the equipment and the use of -3dB voltages instead of -6dB voltages to determine Fl and Fh. The resonant peak of the driver is so shallow that it was not possible to use the -6dB voltages with my data!
The equipment used was a MacBook Pro's internal audio input and output, an OPA2134 as a pair of buffers, an 8ohm non inductive resistor, and FuzzMeasure (software used to produce the sine sweep and to record the voltage at the audio input). It should be noted that the software recorded voltages every 1.345826Hz, so the resolution isn't as good as it would be if this were done by hand with an analog frequency generator. It would also take a whole lot longer ;)
My laptop's internal audio input/output had a strange non-linear thing going on independent of the load and output level, so I recorded the loop through response and then used that to correct the driver's recorded response. That seems to have worked well but made things more complicated for me; especially since I used Excel to graph the data... and I must say that Microsoft intentionally handicapped the office software for Macs because it runs about 20 times faster on a 3GHz P4 running Win XP than on 2GHz core duo running OS X.
Anyway, if anyone has any comments or thinks I did something wrong with regards to measuring the T/S parameters please let me know. |
|
|
| Colin |
I have fuzzmeasure here but have yet to use it. (It's waiting until I get a decent mic and preamp to connect to my Powerbook.)
The variation from the Jordan published data might, then, be equipment or methodology, do you think? I know Ted uses a specialised testing rig and dedicated PC for the job. It used to be the MLSSA system but I believe it is something more advanced these days. It makes it hard for anyone experimenting, rather than using one of Ted's or GM's published designs. |

I am certain that it is both! Anyone who has tried to measure and calculate the T/S parameters using the method I used can tell you that it never seems to produce the same values specified by a manufacturer.

Please keep in mind that my results may not be accurate!!! Even small errors in the measurements will have a significant impact on the numbers used in the T/S parameter calculations. My setup is far from ideal and was certainly very different from what Jordan uses. That alone can be enough reason for the variation. Also note that I was not intending to rely on the absolute accuracy but the relative accuracy of the results for matching purposes. Again, I do not know if this is flawed logic but it made sense to me and a few others I posed the question to.
I have no idea what specs are typical. This is the first time I've held a JX92S let alone measure one :) |

| I apologize to all for the wait! But as I said a few posts up, I have begun shipping. The first three pairs of drivers went out today. Once I figure out how to print the shipping and insurance forms online things will go faster. Regardless, tonight I will send emails to the next 10 or so people in line. |
|
|
| t-head |
Brian,
For domestic shipments using flat rate boxes and USPS, go to USPS.com. You can use clicknship to print online, including insurance up to $500USD...
t |
|
|
| BWRX |
Hi t-head.
Yes, I know where to go to fill out the forms... Earlier today I asked the people at the local post office about what weight to enter because that is needed or it won't let you continue filling out the form, even though weight is not an issue with the flat rate boxes. They told me to just use a bathroom scale and round up to the nearest pound, so that's what I'll do from here on out.
I was told I can also fill out the customs forms online, so maybe I'll try to do that for the Canadian and European shipments as well so I don't have to fill out the forms when I get to the post office. |
|
|
| t-head |
Brian,
Sorry I thought you were having trouble filling out the forms...Just weigh one... a local shipping center or your local post office will weigh one for you...the rest will be the same...as for customs forms, you can fill out online but they are repetitive and a pain...good luck...if it helps, contact me offline and I can send self-adhesive forms that print perfectly with USPS and stick on the boxes for domestic shipments...sorry again...
t (Richard) |
|

| Colin |
I would go with the Jordan measured specs when calculating cabinet sizes etc. I don't think the manufacturer would have allowed them to drift that much and the fact you're measuring them all the same seems to preclude random variations. I didn't even know you could use Fuzzmeasure for driver parameters, I was planning to use it for finished enclosure measurement. Anything else is far too complicated for me ...
Good luck with the packing and despatching. I take my hat off (if I knew where it was) to anyone who organises a group buy like this. |

Whether he likes them or not means little to me...I listen to my pair daily and absolutely love them.
My little bookshelfs matched with a small sub makes a heck of a 2ch system.
In fact, I think this second pair will go downstairs in the theater with my tube amp I am no longer using so I can have a 2nd 2ch. |

I wouldn't mind at all if he wants to build something with my drivers. I'm a lazy sum*****. :D
I have a pair of CSS FR125S in 7L ported boxes. I don't think measurements would begin to do them justice. Their sound is so direct and engaging. What makes them special is not going to show in the FR and TIM results.
Thanks for organizing this Brian. BTW, how much money are we saving through this group buy? |

| Well, markaudio sells the JX92S for $360/pair plus shipping. You do the math :smash: |

Yeah, my original pair was about $390.
Shipping was awesome from Hong Kong though...Imagine my suprise when the USPS man came on SUNDAY to deliver! |

Has anyone ever built a BIB, or the Tuba horn for these, and what are the opinions of the Jordan cabinets, MLTL etc on the site?
Ideally, I would like to avoid baffle-step corrections if at all possible as my amp only does ~ 5 W per channel before it starts to distort enough for me to notice.
Good luck & good fun to all.

Initially, I plan on trying them out in sealed nearfield monitors. Some of my amps are only good for about 5W too, and the Jordans don't need much power to get loud in the nearfield. |
