Hi Paul, its good that you search the archives because the subject kinda got used up. You can only say so much about a Butterworth crossover. Its unfortunate also that Zilch passed away around that...
Hi Peter, long time no see. Hope all has been well. Did you finish your 9846 project?
We have been away all summer and back home now. The Altec board seems to think that I died. LOL
To quote...
Altecman, sorry for not replying to your question.
We are away on Summer holiday with little computer time.
Hopefully others can chime in for now.
Good luck with the project.......................
Hello again Altecman, I would make it removable at first to make sure everything
is working out OK. There is a chance that the added weight sticking out may make
the speaker tip over. I'm sure you...
The wood thickness is all 3/4 inch except the cover as shown.
I believe these pics came from member 'arawak1969'
who should get proper credit for them.......
Hello Altecman. I found the attached picture in my files. Hope it helps.
If you can search my posts here and at the Altec Users Board, there is a
lot of info about the 9846 over the years....
54336The 9846 used the 30904 attenuator equalizer network as shown in the diagram.
The 9846B used the 30923 with the amp.
Your serial numbers mean (Manufacturer number) (year) (week of manufacture)...
Interesting, thanks Earl. The only way I can calculate a 2.7mh coil to work
is if matched with a 21 uf cap, which raises the crossover point to 650hz.
I think the mystery still continues with this...
Hey Gang, was it finally confirmed that the 8B was a combination
of the 8A and the 30904 as in the preliminary diagram?
I only have an 8A here and the equalizers.

Their were 5 versions of the 846B according to the reference page.

Let us know if you get them or not.............................

Hi gang, haven't been active with the hobby but the Adcom is still
in service with almost daily use for 5 years. With a TV in between,
it made a great instant home theater. It was "set and forget"...
Nice thread going here. We got to see him at the Litchfield Jazz Fest in 2006 jamming with an
amazing collection of fine musicians including Renee Rosnes. (Pics below).

when I took these apart I found I had a 808-8a driver instead of a 802-8D. They both use tha same diaphram( 34726 symbiotik). Does it matter that I have different drivers and what is...
"I have a 9846-8a and want to know if terminal 2 is pos and terminal 1 is neg(on the horn). I also have a attenuator(30904) but the info says it should be a 30923. which is the right one? no one...

Hello gang, that is a great looking crossover for sure.
It seems that phasing problems bother you as much as
they bother me.
Adding a tweeter causes chronic phasing problems anyway
but you could...
I should be more subtle with my humor.
Dave,
There is the smaller Altec 9844 to consider with a 2"X10" port
if you want an old school center channel.
...
"why did they do it this way?" It seems a whole lot easier to put a couple of rectangular/round ports next to the horn but here they have complicated the horn mounting and cabinet construction...
Thanks Dave, I gather from your picture and this detail
that the whole top of the horn is suspended in air and is
part of the port, along with the sides.
I can see that it will be difficult to...
Hello Dave. Really nice. Congrats.
If you still have them open, can you measure
the port openings on either side of the horn?
I have never been able to determine it from the plans.
I built an...
Very good Robin, I wouldn't pay that much either.
I found my Empires at a garage sale years ago, real cheap.
That's the way to find these old things. Makes them a lot more fun.
Its great you...
Do they really sound decent?
Yes they do. They did best here in the smaller room placed just out from the corners.
They really came alive then. Before that, I had them in the living room, either...
You must mean the Empire Grenedier
I have a set in my downstairs Bar.
The longer you spend there, the better they sound.
