Default OBERTON drivers ? If yes, why not anyone using them

There is this European driver manufacturer Oberton

Home

They seem to have many interesting drivers

Has someone actually used these ? Those 10" and 12" midranges / midbasses for example

Some of their compression drivers looked quite good on paper. Hence I don't trust something to look very good but have next to no information on the internet about.

Oberton drivers have a good reputation among european PA builders, both DIYers and professionals. Nothing special, but very OK drivers. They get underrated because of their country of origin, it seems.

That may be part of the problem: since no information available no one dared to use them, and since no one used them no information available

Well, the availability seems to sparse. Only few online shops has them.

Oberton 8MB201 was tested in an German magazine last year.

It got rather good marks

Die Klirrwerte sind sensationell niedrig,
selbst bei 105 dB erheben sich K2 und K3
nur stellenweise über die 1-%-Marke und
zeigen keinerlei Ausreißer. Der Wasserfall
zeigt, dass die wenigen Resonanzen harmlos
sind, sie klingen schnell ab.

People no want to use drivers with "sensationally low distortion" ???

Well, i have used the coaxial 8cx with good results.

Welcome to Flickr!

The could have done a better job on the throat and the voicecoil is sticking up a little to much.

But for a battery drive partyspeaker they worked out really nice.

I used a minidsp+miniamp.
Then i used autoeq on REW to make them play as flat as possible way past the crossover point.
Applied a seccond order LR at and adjusted delay until the phase looked good.
