No BSC as of yet. And they deviate quite a bit from GM's design - the cross sectional area is 25 in^2 instead of the specified 30 in^2. I have them right up against the wall, so I think that is removing the need for BSC right now - though when I pull them out into the room, they definitely thin out. However, I have a 5 year old and a 3 year old running around, so they will remain at the wall for the near future.
Di-pole front horns
Design originated here: http://timeandtubes.blogspot.com/
I built them this past weekend.
I used a Fostex 126E and run them without a crossover. Subs come in around 150hz and are connected to pre-outs. They are a di-pole design, so nothing is behind the driver. They sound very good.

Re: Di-pole front horns
would it be too much trouble asking u to start a new thread on fullrange forum, to give us more details on dimensions etc?

Nice
Very elegant design...
Will you share the dimensions so I can build one pair?
I would love to try your design on my 5Dnf Feastrex drivers.

For some reason it won't allow me to start a new thread without doing a "search" first? If someone else can successfully start a new thread, I'll post a reply in that.
I've e-mailed the designer to see if it is okay to post the CAD drawings of this speaker. In the meantime, if you want to put a saw to the wood, e-mail me and I'll send the dimensions to you.

Hello all!
I just started on this site so... forgive me my clumsyness.
I drew up the Conical Open Dipole Horns a long time ago...
I'll try to get a PDF attached so you can see the dimensions.
The re-design I did for cervelorider allows any full range speaker up to 170mm.
That would be a FE166E for example.
I use them with a FE103.
The need a little support at the bottom, I use a Clipsch Eckhorn at a very low level...
All run of a 1.5W amp..

and two more pdf's...
This time with the dimensions.
If anyone needs cad drawings... let me know.
I have also build some other Dipoles.
Using a couple of EV SP15B's and a fostex tweeter, they sound awsome!
The COD horns need less power

told you about the clumsyness...
looks like I can only attach one file at the time.
So here is it all, zipped..
Sorry for that..

Re: Nice
This is what I run them with....
The purest of the pure..
1 dissimilar Triode.
Class A
Single Ended
Single tube
12 components per channel.
1.5W
With nothing in the signal path, apart from the tube of course...
6EM7.
After you've listened to this, you'll never want anything else anymore...

Do you have a schematic for that amp? I have some 6EW7's that I want to use. From memory they are essentially 6EM7? Except for the 9 pins?

I started a new thread. You may want to put this information in the Di-Pole front horn thread as this is the photo gallery thread.
