Has anyone actually received a driver from John in the last few months?
I ordered a couple of 12" Lambda's back in the spring (I'd have to look up the month). I waited for at least a month or two, then called to inquire. I got an E-mail on July 25th, saying that the drivers would ship the following day. Didn't happen. Kept calling every couple of weeks and leaving messages asking about progress. Got a mail in late September with a UPS shipping number. Only problem is, the shipment hasn't been sent. Called a week and a half ago and actually got John on the phone. He said they would ship out that day. Um, well no, didn't happen and no one answers the phone.
So, do I write this off and get on with life or can anyone offer me a glimmer of hope? I've got some time now to finish my project.

I received 4 15" TDX's faraday's around 2 months ago now... from john
after waiting around 2 months for them
they are quite honestly the greatest sounding drivers I've ever experienced
IM john about status... he's a VERY busy man.... it's worth the wait though |

How did you pay for these? If you used a debit or credit card you can just have the bank do a chargeback sice you paid for these and never received them.
I wouldn't wait for anything that long - after you've gotten your money back you should call them and tell them to let you know when they're REALLY ready to ship. Then tell them to ship FIRST, and you'll pay upon receipt - since they sat on your money for so long they should be willing to let you have their product first, and trust you to pay. Afterall, that's what you did with them - gave them your money and trusted them to ship, a trust they failed to fulfill.
If your money is good enough for them without giving you the product, their product should be good enough for you without paying them up front.
My 2 cents. :D |

just call john... he will refund the money as soon as you call :rolleyes:
john runs the shop... by himself and builds a lot of drivers
IM john at stryke23x
tell him that if you don't have the tracking number by friday you will cancel... he will get them to you by then
it's worth it ... these speakers are amazing
John's a good guy... albeit distracted and busy...
I had to bug him a little with mine... problem was his builder quit in like 1st of july so he's been alone since then
if you want to go with worse options john will refund your money... |

| Received 4 Lambda Dipole 15s, and an SB15 long long delayed, but worth the wait. The SB15 was a B-stock special and was thrown in free due to delay. I can barely make out the cosmetic reason it was B Stock. |

| What do these cost anyway? Would they be a good substitute for peerless XLS in the Linkwitz Orion? Do they have a 10"? |

| By far the best way to contact is by phone. Lambdas were offered in 10s, 12s and 15s and featured copper Faraday ring motors. The dipole versions have underhung motors, high q, and claimed extension to 2khz. The 15s were on sale at $279 for one, $179 for a second, dont know if still are. $269, $169 on 12. |

I didn't pay near that ;)
extension on the apollo's is to at least 7khz... WELL
the TD series I have sound fantastic full range... with extension easily past 3khz |

the peerless is a baby to the lambda ;) for many many reasons |

| The first thing I can think of off the bat is that the Lambda's inductance spec is less fictional than the Peerless. |

/hehe
also I don't believe the diameter of the peerless is alum sleeved like the lambda... the plots I have for it show extension on axis flat to 5khz and knowing nick these are true
FS is ridiculous on the 15's... extension to 32hz ported is incredibly easy |

I hope he sorts things out,hes got a good thing going. There is such a thing as too much business!
In the meantime everyone goes for alternatives...
Some one go work for him! |

The Peerless are likely a weak substitute for the Llambdas. Some of the best drivers ever made. I'm glad to see John has picked up where Nick left off...
Well worth the wait.

We have lift off. Looks like UPS has two packages in transit. So for all you Lambda lovers, there's hope.

New News: According to John, he is going to speed production by having the surrounds, voice coils, and spiders attached to the cones by the Chinese cone supplier so he can just make two glue joints and ship the drivers out the door more quickly. A TD15X with Copper Faraday is $279.
And AV (Aluminum cone, Santoprene Surround, Long Displacement) and SL series woofers (Slim design, patented Nd motor structure, long throw) are also pre-assembled and in-stock in decent numbers according to John, with an estimated 24 to 48 hour lead time on shipping if all is well. All preorders for these drivers have been filled.
AE Speakers is indeed plugging along. I suggested to John that a good place to look for replacement help is in the demographic of 18-to-25-year-olds who are seeking employment in the car audio installation field.
Indeed, if people are looking for a quality product, AE Speakers is an innovative business with a proprietor who is uncompromising when it comes to quality. That is why he stopped sourcing the AV series woofers from TC Sounds - not enough attention to quality. And I'll throw in my personal testimony - the AV series woofers are some amazingly musical yet beefy drivers. In their recommended enclosures, they really shine. |

Hi Sheldon,
Your woofers were an extreme case of things not going well. Right before yours I ran out of motors for the Lambdas with copper faraday. I had a guy working for me doing the machining and things just didn't work well on that. It left me with no motors and nobody to make them. I'm capable of doing the machining, one of the many hats i wear, but time is a factor. If it was just an issue of machining parts for your two motors I could probably do that in an hour or so. The problem comes in when they need to be plated. The plate shop needs 60pcs minimum for me to take them there. I'd say by the time I face off 60 back plates on both sides, bore the hole to fit the pole, turn down the pole to fit the copper and pressfit into the backplate I'd have a good 20-30 hours into it solid. Then the poles need to go in the freezer so they shrink enough to press fit. They get sized 3-5thousandths larger than the hole, shrunk down, and then pressed. This assures a pressfit that will never come apart. After that the copper tube on the inside needs to be sprayed with accelerator and the pole with the adhesive. The copper gets pressed on and the glue cures. Once that is done they get put back in the lathe and the top of the pole is drilled and tapped to accept the phase plug. All in all I'd have more than a full 40 hour week to get the 60poles done. IT's taken me this long to finally get those finished up.
I'm looking into finding some kind of small tank method to plate pieces one at a time by hand. The problem is that I'm moving the shop home and the plating isn't something I can probably do here.
Your drivers did ship out last week as you have noticed and I covered the shipping cost. Thank you for behing honest with me too and letting me know I never charged you for it. With the way my books are right now I probably woudl never have cought it. haha
Let me know how things work out for you. Send some pics of your project. I'm trying to get the gallery fixed on the website right now.

Thanks John,
The woofers arrived in good shape. Very nice too. It was a nice surprise that they are still shipping with the phase plugs. I know they sound great, because I've already tested the 15"er's. They look very nice too.
Doing all the operations involved in construction speakers along with all the other stuff that goes with running is business, and having to do it alone is a tall order. Sounds like you are digging out and getting back to level ground. We'd all like to see you successful. Not so many items of this quality available to DIY'ers.
I've described some of what I'm doing in a thread on Unity Horns. I'll post pics when I get near the finish. Should be done in a couple of months.
One question: Do you have specs. posted anywhere?
Best Wishes,
Sheldon |

Does this mean the Ae IB 15's are still shipping with the phase plugs?

| I think you should be able to order them with them. If not now, certainly very soon. I think John commented that when he runs out of phase plugs, he's having more made. But he will have to answer that himself because I don't remember for sure. I'll ask him and see. |

it's such a pretty driver... the phase plugs on mine are the longer beefier ones than this

| Have you actually contacted John about getting replacement woofers? I have never known him to not take action on a complaint like this. When two IB15 woofers had glue joint trouble, he tested whole batches to make sure they were structurally sound. This isn't right to blast the guy publicly for these issues if you, or the interested party, hasn't contacted John. |

Hi Thomas,
Who did the measurements, and what were the conditions and equipment. I see a few things that cannot be right. First off, Mms cannot be measured correct. The physical mass of the cone should be about 100grams, plus the coil around 65, plus half surround, spider, glue, dustcap, plus the loading. Mmd should be a little less than Mms because it is the physical weight only.
Also, Vas is much stiffer than it should be. The spiders do have a very stiff ring of resin on them towards the middle, but that shouldn't affect things that much. My initial guess is that the method(delta mass) to measure Vas and Cms was a mass added method. This is often not very reliable. Both with the woofer tester and with praxis I used to get erratic results. A much more reliable method is the delta volume where you take measurements in different known volumes.
Although everything looks off by a lot, putting the Mms in the approximate range it should be in shifts parameters back to where it should be. Cms being about .44 instead of the .19 that it measured at shifts everything else dead on. Both of those parameters would be wrong together as I said if the mass added method wasn't perfect. The mass as measured cannot be correct because the parts alone weigh much more than that.

People need to understand that I'm a BIG fan of John and his products. If one looks at the IB gallery pages one sees a higher percentage of IB's built using his drivers than any other supplier. However in recent months communications with him have been quite problematic.
Posting publicly was the most expedient way I knew to get this particular situation straightened out. I fully realize posting wasn't the most politically correct approach, but I can't be responsible for providing product information and support when there are issues (real or perceived) with John's drivers. And unfortunately that's the position I'm in when I recommend his products and it's difficult for customers to contact him, which it is....
The testing that I posted was done by one of the people building an IB using 8 of the IB15"s. John's posted the same reply to him on the IB forum. |
