I can't go longer than 2m. Any suggestions about configuration of horn with this length limit ? May be higher frequency ?

Curve the horn. If you Goto channel will not care any HF over let say 150-200Hz then you might curve the horns, similar to what WE did with 15A.

HornResp can help to get desirable frequency response and other parameters. But I don't know how to use it for GOTO drivers. I don't think that I can get Thiele-Small parameters for modelling. So, only experiments...

Actually you might get some TS parameters for Gotos if you find right people to ask. I do not have them but I am sure there is somebody out there who do. The problem is that those parameters are very much irrelevant and you should not be interested in them.

I think I missed about your 40Hz horn. I don't see any information or reference at Macondo dedicated web-page (http://goodsoundclub.com/MacondoAcousticSystem.aspx).Can you suggest what thread to read about it ?

Longer horn will need another room.

God, I wonder how many people out there keep saying it!!! That is of course unfortunate truth… BUT the whole idea to be creative is to find a way to incorporate a larger horn then the room can afford. There was a saying in Russia that Jews do not work harder but smarter. Not that I agree with the saying but it is not a debate about racism but rather an illustration that there is always another way to think the problem. Do not forget that the thread I linked above was followed after this thread:

It is possible that you can go over the walls or do anything “creative”, well then curve the horn or introduce one or two bends. The 90% bending is very complicated subject and it very much might kill everything, Still it is doable if to approach it with proper direction and proper techniques.
