After the first months with my horns.. (Oris Horns)

by Balthasar, Monday, November 03, 2008, 18:01 (3275 days ago)

Hello all together..

The first jear with my Oris horns is nearly gone, and listening to them is still a great fun:grin:
But in the last months i found some little things to work out, now it´s all done.

Here are some pictures:

A little more to do inside my amplifier:

I changed some resistors, put some JAHRE silver-micas and MKP1837 inside, new MILLS MRA-12 resistors for the kathodes, and some other small things.

The 82µF-VISATON elkos (for the horns) are gone, new Mundorf elkos (47+33µF + Jahre silver mica 89900pf) are working much better there now.

I think the next step is a change to Lowther drivers, the Fostex are the weak points now i think:confused: Maybe next time.

That´s all for now, have fun and best regards:bey:

Hello Ralph,

Thanks for the update...you're a busy man! :cool:

Glad to read that you are still enjoying the music in between tweaks. :wink:

Another next step could be to add a tweeter (like the Fostex FT17H) to get some more freshness off-axis with the 206's...?

Hello Bert..

Thanks :blush:

I never thought about tweeters, ok the sweet-point is not so big, but thats no problem, this room is only for music-listening, and only one chair (the master-chair :cool: ).

My dream is still a pair of Lowther drivers, or is that a wrong way for a step-up?

Regards, Ralph (not busy today:grin: )

Hi Ralph,

This doesGC't mean that you should not experiment...

Nothing wrong with that from which the DX2 or PM6C's already do several things better than the 206's... :wink:

Thanks for your advice Bert:ok:

I think the Lowthers are a better choice, in my opinion the horns were built for Lowthers, not for the Fostex. Please correct me if i am wrong with that.
So everything with the Fostex looks a little like a compromise.

For the first time the Fostex are ok, they work well, but it´s in my mind: "Get Lowther, get them!":prankster:

Are there big diffrences between the DX2 and the PM6C?

The Fostex is a nice driver to start with if you are on a budget...many things can be improved here! :yes:

Are there big differences between the DX2 and the PM6C?

Between the standard drivers there are a few major differences. It does not show on the Thiele-Small parameters but the materials used sound different.

Think Ferrite versus Neodymium, big sized magnet versus small, white paper versus yellow paper...

Hello Bert..

Of course your are right:wink: , i don´t know all those Lowther-secrets at this time, but i found some informations in the web, very nice stuff!


The PM6Cs are on top of my list! By the way, did they need any crossover-parts?

Hi Ralph,

...did they need any crossover-parts?

Basically not but if you want to play very loud (at low frequencies) then you'll need to cross them to protect the driver against damaging due to too much excursion...
