Ich habe eine! But why's that? Because the WL5 is with 1,4" throat?

Becasue if you look carefully at the bottom right of your post you'll see an Edit button. Sorry for being so rude.

@ Poon: I have re-read the thread and you do have a point. If the driver could reactance-anul (in a 140Hz mid-horn like your Porn Horn) with a large rear chamber (like what Bill Fitzmaurice suposedly does with his bass-cabs), then one could look at a hybrid like you suggested. However one would need a really weird (OEM) driver to have both the ability to funciton in a large rear chamber (ignoring resonances for one) and the strong motor/light cone to be any good at loading over a high bandwidth.

One could then look at loading the "port" closer to the throat of the horn and try and reduce its Q. Not something I' try on a mid-horn anytime soon, but one never knows.

Hmmm, edit button. Great. When did that happen?

I didn't see it because in all other boards I visit it is near the quote button....

BTW I think you have spoken too much english. Glasses is singular in German: Brille.... :)

Venting the rear chamber of a midhorn often results in loss of max spl capability in the low mids.... I don't know numbers, but it's basically a fact...

Except if the diver paramers are such, that you can still reactance-anull. however I have my doubts whether such a driver exists.

@ JD01, fair enough. I am fairly fluent in three languages, so it is inevitable that something will get mixed up somewhere. Languages aren't exactly my forte.
