Anyone built a TB W5-1611 Horn?

I think i saw a TB W5-1611 backloaded-horn somewhere in this forum. I did not save a link and it has been a while so i can't find it anymore.
would be glad to receive some more information!
thanks @ all

this is a very nice horn, absolutely great for voices, pinpoint imaging. the sound has a slight nostalgic character (I mean this as a compliment), adding a RCL as BSC could make it more neutral

Great, thank you very much Henkjan!
I think you are the one who developed this horn, right? Did you make any measurings you could post?

Ok, i figured out what is a RCL. But i don't understand the shortcut BSC, i only know it from economics - balanced score card :whazzat:

As a RCL smoothens the frequency response, which frequencies should be reduced? I already have the W5 in a 10l BR called Sarah (developed by The_Guitar_Tux, published in the german Maybe some notch filter can be re-used?
If it's OK for you i'd like to post your drawing in the hifi-forums Sarah-Thread. Some users are also interested in a W5-Horn. Does it have a name already?

I did not devellop the horn, that honour goes to Roland Breteler from Crafty loudspeakers.

I did not measure this one, since I did not have it long enough. but from the tonal balance I expect the usual midrange 4dB orso hump that you could flatten using a Baffle Step Correction. but I would advise to listen to it first, the tonal balance is not unpleasant and makes voices sound even better. already after a few minutes listening your brains will have gotten used to it and does not bother anymore. only when switching between loadspeakers it is clearly noticable.

The Sarah is a much smaller box, so I expect the main notch (the one for the BSC)would not be very good, you might want to try some of the smaller ones aimed at driver resonances (personally I think they are not needed)
