Wonderful horn, Chris. 160Hz is very-very interesting size for using S2 at it bottom knee for a lover mid-range channel. I when to 250Hz (I did not go lower because some my own reasons) but I think the 180Hz should the perfect frequency. With damping the exterior it is complicated. It is absolutely necessary sonically but any damping that I have seen so far make the horn to look ugly. That is why I usually advocate the thicker walls – although it makes the horns more expensive to make and less “airy” looking but it make then to sound better.

Chris, please keel posting your observations when you get the horn and will teach to sound in your room. It is very educational….

Regarding “cut in half”… Well, how frequently do you order the horn of the given side? I bet that you will have one 180Hz over the period of your life. (!) Does this fact suggest that it makes sense to pay once a little more and do not sacrifice the result? Well, the paradox is that in order do not sacrifice the results it does make sense to cut the horns (:-)… but not for the sake of cutting the shipping cost.

You see if you are wiling to try “some different drivers” then they all have different throat seizes. The transmission between the throats and driver output is very critical part it is should be perfect and without any steps. So, how to do it? The most effective and elegant way is to target the horn to 2.5” for instance and then introduce an interchangeable extension of the length enough to finish the given profile at the necessary diameter. Unfortunately it will do little to help with shipping expenses, as it should be cut practically at the very end. Also, it is practically not implementable with the thin-wall-horn as you would need “mass” and sire to implement some attachment mechanism. Juts for sake of illustration here is how John Hasquin has done in my 400Hz horns. Frankly speaking it is the most versatile implementation of the concept that I have ever seen.
