I have completed the horn (see a few posts back) and to make a long story short: great!

the horn respons compensates (as predicted and hoped for) for the baffle step, so these puppies play without filter components: music pure. imaging is absolutly fantastic, among the best I have heard, especially voices are so real, scary almost...

attached a better drw

Hi Henkjan,

I am also working a project for 1611SA... However my box design knowledge is not much as yours..

Ok... I dont know anything about the transmission line or horn loaded boxes (or quarter wave something)...

This is the situation;
I have designed a simple bass reflex box for 1611SA (a 17lt and tuned @54.9Hz) . As WinISD says it will give ~52Hz @3dB with this box.

However after I saw your project and your comments on it, I am not sure to make my project anymore.. In fact I dont know the benefits of a horn loaded box but I guess its better than a simple vented box by the meaning of phase response..

Anyway,
I have examined your project, everything is ok but the felt and the baf wadding..

May you explain a bit please? Or do you have any picture of them? Because I think I will make your box.

Thanks a lot in advance..

Ozgur, what is it exactly that is not clear about the felt and the baf?

imho the best part of these horns is, that you can use them without any filters, and yet have an (almost) neutral sound

What shape will be this felt and baf?
I am asking that because (as mentioned) I dont know anything about the horn designs...
In the drawing they looks in two dimension so I couldnt imagine how they should be in 3d look.
Means the felt will be filled whole back chamber of the driver?
Or what? I really dont understand

the felt is placed along the wall behind the driver, do in a sort of sqare U shape. the BAF in the top I glued to the wood as well. the other BAF can be placed how you see best as long as it does not obstruct the driver and it will stay in place

(unfourtunately I forgot to make photos)
