AER loudspeaker manufacture

[Jaime]

There are two AER manufactures :
“AER Loudspeaker” and “AER Loudspeakers”
http://www.aer-loudspeaker.com/
http://www.aer-loudspeakers.com/

Someone can explain?
Which is the authentic AER loudspeaker?

Best regards Jaime

look under "diy drive units"

You could say that the other appear to be ok too... but in the light of doing what they do it is very questionable if their quality nor specs are reliable at all
But their site does look very impressive, but you know much of it can be "borrowed" too...does look like quality, but who knows what they actually deliver, when it comes to that

Both based in Stuttgart too.

This is a very sad story. Each of them seems to accuse the other of plagiarism and claims to be the original inventor/manufacturer... civil action seems to be going on... at least from one side.

Now we have this:

versus that:

Houston, we've got a problem...

I'm more inclined to believe Bert Doppenberg.
A German friend of mine bought drivers from him rather than from Germany. I have seen and heard the drivers. If they are fake I'll eat my hat.

 

[tinitus]

I did at some point actually think of an X-partner "thing"

So its really not a copy like BD claims ... question is if one is better than the other ... sounds more like ugly business... and us being hostage

better stay away from AER. Nobody knows what is real and what is fake. If you ask three insiders in Germany you get five answers.
Both of them always refused to offer measurements of their drivers.
For that amount of money they charge, better go for a Lowther. You know what you get and since they use the rolled whizzer cone they are a lot better than in the past.

Considering that the AER is a "Lowther made by Germans", it's
ironic. I did have a genuine AER loaned to me by a generous
Korean DIYer, and I have to say it lived up to the description.

mr. Pass, you are a true (zen)master

 

[OzMikeH]

If anyone has these drivers it would be most helpful if you could send some detailed close up pictures and tell us which AER you got them from.

It will soon become apparent which are the fakes, perhaps they will both be good.

We may well have a case of the master & the Apprentise (or business partners) having a political split up, and that each driver has its own merit

I dont think its a matter of fake or not....my concern is whether they both deliver the promissed quality... which would be expected at this level of cost... would you trust them enough to pay in advance and so on... on the other hand, not many of us will pay that kind of money at all
You may say "not our problem" ... but when links are shown on these pages it is

 

[planet10]

If i had that kind of money to burn on an unseen, unheard product i'd probably be shopping for a Feastrix or an Exact or maybe Fertins.

I've heard the "real deal"...

and must say they are startling. My audio buddy has a pair of these and some Lowthers...he prefers the AERdrivers. He purchased them from RL Acoustique, I believe.

here's a review .

I've heard a pair of MK1s supplied by BD in JamesD's perspex Quasar OBs with Supravox 285 12in woofers supporting the LF. Startling sounding device. I like them, though like Lowthers it doesn't suffer duff ancillaries period, let alone gladly. I'd love to hear what a pair of F4s & a decent preamp would do with them. Not as fast or as efficient as Steve's EX4s (relatively), but possibly a little flatter.

I know Filip Keller personally, visit him twice
and heard some of his drivers,

last week I contacted him last.

If I look his mesurements, I have a problem,
38 Hz reso and the measurements have 48 Hz:

than Klangwelten, than the drivers, than scroll down.

form your own opinion about this, 4 m distance etc.
more or less no difference etc. how he got this
graphs, he didn´t explain it.

if I look the measurement of the Raptor it look like Lowther
not like his measurements.

I´ve tried to get resendable samples to compair it
to B200, PM6A, Fostex, AN 8" in my sathorns with
measurements, I send the horn-sat to him, he wants
it, but no samples no testing by himself, and he likes my designs!

What shall I think about that.
He won´t know how good or bad his drivers are in comparison
to the other, specially for this price.

Or is it only a strange personality?

 

[tinitus]

You obviously dont know him personally😉

I think that fullrange drivers and tubeamps should not be measured

 

[hm]

call him and ask him,
a smile doesn´t help that
you will tell the people in this forum:
I lie.

where is the moderator?

I very upset about such allegations.

 

[Nelson Pass]

I looked up the picture of the AER DM3 that I had. Here it
is mounted in a modest BLH:
