TO FREAKING COOL!!!!!
I love it... it's art and just the way I like it....
hopefully you also found out the boxes and baffles are useless
Hi Randy,
Thanks!!!
I really wonder when it all went wrong with boxes and baffles and stuff....
This is it.
I've buld open horns, open baffles....
but this is just way beyond all that.
cheers!!
Orion 4
Major changes in the bass section. SL seems to prefer using the force cancellation of W-Frame dipole.
It is their first showing at RMAF 2010

An externally hosted image should be here but it was not working when we last tested it.

I heard the new Orions at RMAF, I thought they sounded really good (my first time hearing any version of the Orions). While I was in the room, SL mentioned that he's working with Seas to get woofers more appropriate for this role. He said something like "Don't go out and buy the drivers I have in here, I'm just using the best of what's currently available".
Different compared to what? Like I said, this was my first time hearing the Orions. I never got to sit in the sweet-spot chair, but even from off to the side, they did one of the best disappearing acts of anything I heard at the show. The dynamics were excellent too.
The few times I was in there, they were playing orchestral classical music. I didn't hear any vocals, or drums / upright bass / stuff like that. So take my comments in that context. I thought the highs were great with the music I listened to. The bass was more than adequate, but maybe if I'd heard some bass guitar or drums or piano, I might have changed my mind on that.
Also, as you can see in the picture (which appears to be taken by a friend of mine, so I was in the room when this was taken), there were no wall treatments, and I don't remember seeing any bass traps either. It was encouraging to hear how good these speakers could sound in a fairly normal hotel room, which is actually a pretty bad room. Most other rooms had at least bass traps, and drapes / rugs over the paintings, some actually had absorption / diffusion on the walls as well.

my little aliens
Are done!!
and they sound terrific too!
They could do with a bit of suipport in the low.
I measured and under 80Hz there is not much going on anymore.
Might need to move my Klipsch eckhorn upstairs...
The high is taken care of by a fostex FE103 and the low by a 305.
The sound is absolutely amazing!!!
this is my listening, experimenting room.....
lot's of fun there

there are Telefunken RS607's.
huge.
and sound absolutely pure.
it's just your electricity bill............
about 1kW in for 100W out
Update
A little update on "Dipol 08" since the last pics
in this thread were from the build phase ...
In this pic you can see the rear "filler tweeter" panel,
which is attached with the single small screw ontop
of the uppermost driver.
No, this does not do really low bass:
Recommended crossover frequency to a dedicated
dipole subwoofer is 80Hz. Standalone lower frequency
limit is around 70Hz according to placement.
Sufficient for chamber music and some jazz recordings
though, since the rolloff is very smooth ...
1st order PLLXO is used to rolloff the dipole line array
below 80Hz, which also improves dynamic headroom,
since cone excursion is significantly reduced.

congrats... I love them... but do me a favor as I am a detail nut.. texflex those wires along and try to figure out a simple wire management solution... I know this add's 0 to the performance.. but you've made such a killer piece that it just needs that last .05% to make them perfect IMO
Yes. of course I'll do that.
take some silicon transparent wires running through tthe interior.
and a the filter in a box on the floor...
I'll post some more pics when they're perfect(er)
right now, I just have to sit down and listen to them.
The sound is, a friend told me yesterday, more then stereo...
thanks

Which is about perfect. (..it's kind of a big deal for most OB designs, but a lot of people just don't seem to "get it".)
I was thinking the same thing..
(..basically, "..forget the loudspeakers, what the hell are those amps!")

well.
the biggest SE triode, DC coupled amps in the world?
decided to build it.
started about a year ago.
simply because I bought a whole bunch of these old radio emitor tubes....
stupid thing to do, but there you are.
wife asking: what are you going to do with all these glass things???"
this is my blog:
TIME MACHINES AND TUBE AMPS
on the right hand side, scroll down a bit, then click on "RS607 or Tubezilla"
You can see the birth of one of the biggest single ended, DC coupled triode hi-end audio amps.
learned a lesson or 2 doing it.
let me know what you think!!
cheers!

Hello Scott,
here's my personal shortlist of some advantages you
get from this:
-Abstinence from LF allows to design for more
frequency independent horizontal dispersion
without side lobing in the midrange when using
a narrow baffle
- The independently movable subwoofer(s) can find
an optimum position in the room to excite the lower
room modes in a balanced way without affecting the
position of the satellites, which in turn should find
their position due to optimum imageing and balanced
upper bass, which is less a problem than LF because
the modal density in typical rooms is much better above
100 Hz than below and above 200Hz the "statistical"
range of most room starts.
- Use of a monophonic subwoofer, which integrates
seamlessly, is possible (WAF issues)
- A dipole subwoofer - which i would recommend - has
a fairly limited bandwidth and can be seriously optimized
for say 30-160Hz, which allows for rather deep
U- or H-Frames and the like ... which are by far more
compact in your living room than open baffles with
comparable dipole path length.
- Placement of the subwoofer in or near a room edge is
possible. Multiplying the effects, completely different
ranges of LF dipole efficiency and balance in LF
modal excitation are available.
This should be sufficient for the first ...
Kind Regards
