In the Thread: How to USE “Resonating Oops” in loudspeakers
Post Subject: I will do it when I have time.Posted by Romy the Cat on: 12/13/2017
I do not advocate injector on the ground. The way how I use my injector I high pass is aggressively, so the ground coupling is not a requirement. If somebody use injection at lower octaves then it might be a merit to do so but not in context of my injection. 
 
It is absolutely prohibitive in my view to have injection with arrival offset, the time aliment is absolutely mandatory. Now, there is very valid debatable question. If you for instance locate injection channel above the teeter then you have less tight vertical horns island. If you have the injection channel located on the side of the tweeter then you have more compact horns configuration but you introduce a horizontal offset and probably too much reflection from the tweeter.  What approach provides more damage to sound? I would have difficulty to answer this question. I did the vertical alignment and did not experiment with horizontal offset. The vertical alignment, since the injection has high output in top octaves, does damage imaging to a degree. Will this damage be more or less if I use horizontal offset? I do not have the answer. I bought 6 months back of so a coupe, of 10” tubes incisures and as I have time I was planning to put the 10” Tannoy in there and try it horizontally offset injectors. The problem is that I do not have now any good harness to hold it on my frame to assure a stable time positioning and time alignment. I will go for this when I have time.
