Hi everyone!
Does anyone have any Tractrix/exponential/hyperbolic plans for the 2105?
I could use a bit of help there.
I would like to use them as mid-bass drivers, because I like the clean and crisp sound they produce and also because I already have them on the shelf.
However the sensitivity is much to low for my purpose, (2105/2445J/075) so I went looking for some formula to calculate some horns and to see if they were suited for horn loading, which I found them to be by a wide margin, but then I got stuck on the calculations because the formula didn't say if the parameters were in feet, inches or in the metric system.
So I wonder if anyone could help me with the measurements preferably on a frontloaded horn. But if it's considered that a rear-loaded horn would be better, then of course I would choose just that.
I also think I wan't the horn to work between 290 Hz to 1000 Hz if possible. I also think a square horn would look better and also be a bit more practical as well as easier to build.
Also what kind of sensitivity could I expect from the horn-loaded 2105H?
Grateful as always for any help I can get.
