I have tested my Visaton B200 speakers on the Sachsenwerk open baffle.
I had to mount the B200 from the rear, that I can keep the hole from the Sachsenwerk, but it fits okay.
The B200 is a fullrange speaker, but NOT need a tweeter, as so much other fullrange speaker.
The B 200 have a QTS of 0,75, so you can use on open baffle.
The bass area of the B200 is lacking, as midrange is quite louder, so you can use asimple frequency correction to correct that.
For me the bass is okay, because the speaker is close to the wall.
The sound stage is wide and open, nice listen to.
For people who need more bass, you can add Eminence Alpha 15A woofer.
