OK guys I love all your horns. Great Great work But it time to make a multi cell for the masses. I want a big long 200hz multi cell. 2 part casting I guess. Even just a single row of 5 cells slow opening. Made light so we can either sand fill or epoxy fill on assembly. Leaving the throat clear so we can reinforce with cf as the throats have to be really hard in my opinion. Is why altec used brass throats. Even a horn with vanes would be a compromise. Cmon make my dreams come true. And totally ruin all the vintage multi cell horn hoarders crasy prices that I cant afford. There is just no economical solutions to multi cells out there in the market. They would cell like hotcakes. Not that I have ever bought or sold hot cakes.

Then when you done that make a WE31a copy with slightly narrower profile for stereo. Another big seller.

Hello Jack,

Or there is something you have to explain...


And as we can see on your graph:

the problem I mentionned (increased directivity of the Tractix below 1800Hz) will not be removed by any normaliztion...

Best regards from Paris, France
