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.

I went through your results, and one thing that caught my eye was the lack of energy after 10 kHz. Was this a result of your implementation, or is there really nothing to expect after that boundary from these drivers?

I'm currently looking for a suitable 8-10 inch coaxial driver for my open baffle project, and the Oberton 8CX and BMS 8C250 are currently strong candidates for the "next step".

Give me a day to find the rest of the measurements.

Unfortunately i no longer own these.
But if you ask me and my bad memory, at the levels these were made to play.
You didn't miss any high at all.

What I'm looking for is a coaxial 8" driver that's good for a project that's looking to destroy anything in the High End of loudspeakers under ten grand. The BMS holds a place close to my heart for anything like this for it's ring diaphragm compression driver, which I have some experience with. So I need much justification to go with the Oberton, which isn't that much cheaper than the BMS...
