Oris 150 some questions (BD-Design)

by GC @, Germany, Sunday, October 16, 2005, 00:22 (6738 days ago)

Hello Bert,

after listening to your wonderful oris-horns at AES-Kassel
(your german distributor) i ordered a pair :-D .
I want to use them with a Fostex FE204 (old, but good!!)
and a Fostex T725 as supertweeter (and a KHorn-Bass). Any hints or
advices for this combination ? (selling the FE204 and the T725 is
No option and buying an AER MD 3 is far to expensive in my opinion.)

Another question i am concerned about is the use of this combination
for homecinema.
Normal stereo listening at a high volume levels is no problem i hope,
but homecinema use is something completely different.
It is more full of "noise" and i will not damage this combination
(especially the FE204) with it.
Any thoughts or i am just too cautious ??

Many thanks in advance

Hello Markus,

and a Fostex T725 as supertweeter (and a KHorn-Bass). Any hints or
advices for this combination ? (selling the FE204 and the T725 is
no option and buying an AER MD 3 is far to expensive in my opinion.)

That is a question difficult to answer, I have never experimented of even heard the FE204 or the T725. I am fully "blind" with this combination so any comment would be useless...

Normal stereo listening at a high volume levels is no problem i hope,
but homecinema use is something completely different.

The main difference with home cinema is the bass. Sound effects can be extreme in the deeper bass and if the driver for the mid-high horn is not filtered then it will move a lot more compared to playing music and that might damage the driver. For mid- and high frequencies this should not be much different.

Drivers with real strong magnets do have less problems with bass, these are much more dampened by the magnet (that's why very low Q driver do not give much bass) but it still becomes a problem on extreme playback levels.

With home cinema I would suggest NOT to mix the subwoofer channels to the main channels so always configure the HT-processor as if you do have a subwoofer connected.

Ciao,

Bert

Hello Bert,

thank you for your fast answering !!

No problem with this. I'll try out and let you know ;-)
But i have to admit that i am really curious about how it will
sound. The Fostex FE204 has a limited HF-reponse up to 12 kHz but
the rest is quite good and more linear than the FE206E.
So i know i have to use a supertweeter. Because my T725 i use
in an ACR-version of the klipschorn is a very smooth-sounding
tweeter i think it is worth trying it as a supertweeter with
a simple 6 dB crossover.

For homecinema i knew that there will be a problem at high volume
levels for the FE204 in the Oris. Hopefully a good active crossover
will solve this problem ( HP 150 Hz/ 24 dB). I think this should
protect the FE204 from the worst problems.

many thanks and best wishes from germany

Markus Maier
