 I set two multicells with LF-enabled S3 drivers. I set them on the outer side of Macondo MF.  Playing with crossover, volume and towing of the multicells I was able to a degree to get the effect that would like to get. The pointing the multicells not to the listing position but slightly toward the side wall turned out to be the most effective. I was not able to get any good honk however.

The result that I got made me to think if I truly need an additional semi-side firing Fundamental Channel. Yes, if I were able to painfully substitute my current 250Hz tractrix to 183Hz multicells then I would do it but it looks like it would be too long for Macondo current frame.  To use the multicells as a separate channel to moderate presentational width and possible moderate useful honk is a good conceptual experiment but do I really need it for listening?

 Am a bit not comfortable that I becoming hostage of the fact that I can do it and my possibility to render interesting things in audio drives my project instead of my need to have the projects done.  For all intended purposes the Macondo width is fine as is. In fact last neigh I figured out that the width problem that I noted before came from the improperly bass producing  by PP2000 regenerator, switching PP2000 back to battery give me my width back. So, this week PurePower will hopeful address the problem, do I need my side-shooting multicells?

Well, the side-shooting multicells do some interesting thing regardless what but is it necessary for listening or is it necessary for pure audio objectives? I personally feel that it will be pure audio tricks as Macondo sounds fine “as is” and I experience no deficiency or need for sideways moderation. I might change my mind as I get my PP2000 and will recover my sound in full  but for now I will put the further experiment on hold until I get a feeling that I need any hold from my 183Hz multicells.
