Are you saying you ported the 2405? Please explain what all that sheet metal is about.

Hi Mr. Widget,
The sheet metal has two functions. First of all it carries the 2405 and brings it into the correct phase position.
Secondly the openings at the side serve for the sinking in the 1kHz range of the 2206 (enlargement of the port openings).
The Tops are appropriate for maximum sound pressure in the range 120Hz to 21kHz. The housing for the 2206 goes only up to the lower edge of 2344 (23 liters).
So far the boxes were somewhat importunate within the range of 1kHz. I corrected this so far with a Equalizer. With very high levels flow noises at the openings were audible.
Since two 2404 was inserted before, I would have had to mill the openings larger, in order to reach a sinking and reduce the flow noises. By the exchange of the 2404 against 2405 and employment of the owner sheet metals with additional openings this was now no longer necessary.
Now I do not need the Equalizer. Without tone control it sounds bent.
