AE AV subs?

[sandt38 10+ year member]

Im not sure that using the term "failure rate" or "rate of failure" is appropriate with such a small sample size. Even if every driver sold on CAF failed, that is likely a fairly small portion of the total drivers built.

True, but it was 100% of the sample with the people at hand. Like I said before, i should have mentioned it was a 100% failure rate on CAF, as it is not indicitive of the entire run of drivers.

Even then, my point was more that it is useless to use such metrics or statistics when the sample is so small. For example, suppose only two people from a forum bought drivers, and both of them failed. Subs sold to people on that forum have a 100% failure rate, but that still is not telling us anything useful because the sample size is so small. I would still tally the number of failures, but I wouldnt even approach the word "rate" until I had 50-100 samples on which to draw a conclusion. To me, failure rate implies that you have a sample size large enough that the results are statistically significant on their own. Anyways, Im wasting my time on semantics.

I run an AE sub in my car. It is the C15-1 model(basically an AV15) and it absolutely pounds in a small 1.6cuft sealed box with 800 watts on an MbQuart RAA2400

I have had it a year with no problems at all. I can not praise the capabilities and SQ of this woofer enough and consider it a great value for what I paid(under $200).

BUT

The only problem I have had is buying one and trying to buy another. My most recent story here on his website:

http://www.aespeakers.com/phpbb2/viewtopic.php?f=7&t=1788

I really wanted to stick with a local retailer and with the AE line, but just dont want to deal with all the excuses anymore. This isn't just a one time thing or a months worth of waiting problem. I tried to get an AV woofer a few times over the course of several years and was always left waiting or told something had come up.

This is the reason I am purchasing a JL10w7 today instead of an AE sub

It is always good to see a happy user, as this is the ultimate goal when buying our gear...

But it is a shame to see your latest issue. However, a 10W7 is an excellent choice... A good buddy of mine runs one and we have played with various alignments and power levels... They are impressive drivers for sure.

You should try again, he seems to be shipping out AV10s now.

Doo Doo Brown sold drivers that had problems.. when he was told a problem exhisted he swore its user error.. if your expencting anything over 50 with 1K to come out hte AV your saidly mistaken, the driver will loosen up and when you give it 1kw in a fairly large ported box(3.5) its going to sound like wet farting... i was very careful the irst day ihad it only playing ti close to tuning. seeing as i had a 3.5ft^3 box.. next day i extened hte port to drop the space to 2.9 tuned to 31.. i still had the same results.. the stiffness isn't inadquate, its the actual BUILD of the spider.. i explained excatly whats happens im not going to do it again... hope you get this problem fixed for you customers sake Doo Doo Brown..

Papermaker, john stated that he is changing out the spiders and is now using a new Stiffer "C" spider.

We have 3 stiffnesses of the same spider that fits the AV series. A, B, C. B is 2x as stiff as A and C is 4x as stiff as A. My "former employee" built Kenny's woofer with the softest of the 3 and informed him of that. Yes it is quite soft and we are now using the C stiffness. He has never stated we use "cheap parts" because he knows the fortune we spent on things. That was your claim not his. The spiders are 100% nomex. Nomex is extremely durable, much more so than poly cotton and about 4x the cost. It is virtually impossible to wear out during normal conditions. You have to actually stretch the fibers to break them. They have incredible resistance to fatigue. That is why Rightbrained's tremor twins are still working fine after months and so are other drivers we have sold since then.

Im assuming you guys got the standard spider, im sure john sees the potential problems that the soft spider brings and has NOW changed it as a result from the previous drivers regardless if it was his softparts or user errors, i dont think he wants to chance it.

I should be receiving one of these "Newer spider models" At the end of the week.

Its hard for people to admit fault in their products when they are putting all of their energy into making them.

Papermaker got the stiffest spider, if not something even stiffer. In fact, he WANTED to get dual spiders.

Well im fairly sure that since this has been brought to his attention, regardless if he admits fault. I'm fairly certain that he doesn't want to continue shipping out woofers just to have them all come back at his expense.

I'm sure he is doing something about it.

Yes. He's telling us we did it wrong.

I know he said that, anyone in his position would be defensive, he is trying to make a company. Im sure that was just his initial reaction to defend what he had made. I can bet you that he immediately rechecked every one of his spiders and started testing to see if this was actually true. And i think quite obviously has come to a conclusion. (yes there is a potential problem with this spider design).

Now i am just assuming things, i cannot speak for the man so this all may be nothing but, i think that he is scrambling to fix this problem from EVER happening again, and im sure he would prefer to do it Discretely.

He may not admit fault but as everyone says, he always comes through in the end.

You were also being an extreme dickhead/cunt about the whole situation.

You were also being an extreme dickhead/cunt about the whole situation.

GTFO off John's nuts, will you? Do you even know how long I was an AE fanboi before ANY of this? Or how long ago I originally asked for a driver? Or how long the initial pre-order ended up actually taking? Or how I was willing to drop another few hundred with John for another driver, or to get mine reconed, or how I went out and bought another, more powerful amp, because dickhead kept trying to tell me I had a 300 watt amp when I repeatedly TOLD him it was ~1000 rms at 4 ohms bridged?? Or how long I tried to fix the situation, doing exactly what I was told to do and check with what tools I had available? Like I said, not everybody has fvcking EQ's/RTA's/Mic's/Scopes etc., among other things needed to do half the shit he advocates when trying to fix one of his drivers to actually work worth a **** in a car.

Beyond initial system design, one shouldn't need to do much outside of basic tuning to get a subwoofer to act even remotely correctly in a vehicle. Re-assessing placement or enclosure is a MAYBE. These drivers, otoh, were very different, and apparently need a bunch of help via off-board electronics to make them work in a car. Me being a 'dickhead' about the situation is completely besides the point. I was MORE than patient. When I FINALLY made a public post looking for oppinions of what I should do when considering another driver (another driver from John no less, even stating that I WANTED to purchase another driver from nobody BUT John) I apparently wasn't a good enough ball-licking fanboi anymore, so I was now told I was an idiot and did everything wrong, evne though I PROVED that I did EXACTLY what he originally told me to do.

And look, Basdfreak (papermaker) did the exact same thing,a nd now look at how John's treating him...... This should be an indicationt o ANYBODY looking for an AE driver of what to expect if and when you have problems.

papermaker, I still have not been told what the exact condition of this driver is. I have also been ignored when asking if I could send you a return label to ship it back for investigation. Is it still operational? Is the coil burn up? Did you bend up the cone? If it is still working I'd like to take some measurements on it as is and bring it down to Bumpin Buick as well.

You had stated that the suspension got "soft" and there is no control over 50Hz now. As I stated before, 50Hz and up has little if anything to do with the compliance of the driver and the suspension. You can change Cms from .05mm/N, a very stiff suspension all the way up to 1.0mm/N, nearly 5x as soft as the suspension you have. It will have virtually no effect above 50hz. The system at that point is dominated mainly by the motor of the driver and controlled by your amplifier.

Again if the driver still works I'd like to be able to take some measurements. If it doesn't I'd still like to evaluate what actually happened to it. I'll issue a UPS return label. After I spent $135 to overnight a 40lb woofer to you, a few dollars more to get it back is no problem. I'll even give you a refund of what you paid Kenny for it.
