it is so obvious with simple listening where is right polarity that is you try it you would not have doubts where is “right” and where is “wrong”. It is very clearly where the Red works with Macondo and where they work against each other.
I have to admit that the entire configuration is very messy and pretty much defines any common sense of speaker engineering, still it “works” for what I would like to accomplish and I do imply it. No one who heard my playback since I stated to use Injection complained that Injection has damages imaging, nevertheless I can acknowledge hear the imaging damage. However, I do found that the benefits do overcome the negative side of Injection.
I spent quit a lot of time thinking how to integrate the second order Reds with first order Macondo. Moving the injection channel, measuring and listening I eventually found out that if I was able to sum the maximum amplitude of Macondo and Injection Channel feeding the playback with 9K then injection sound well-integrated timing-wise with Macondo. Ironically it does sum maximum at 150Hz as well. So, currently I have all Macondo running at plus and the Injection Channel along with the “Water Drop tweeter” ruing at minus.
