I can't really make it out on the photo, but it looks a bit like a Tannoy Supertweeter.
Yes, it is but my interest is not what kind of brand he used but why he would need an additional tweeter in the first place? The multi-sell MF channel would probably go up to the 5-8kHz. (I would not run it high then 3-5kHz) If so then the JBL slot tweeter (let call it JBL at least) is kicking in let say 8kHz – it is an OK location for HF driver, even I would prefer higher.

Now is the question – why the owner used an additional tweeter if he positioned it as he did. If it were a regulars let say Tannoy Supertweeter at 13kHz then he would put it in phase with JBL tweeter. The location where the Supertweeter located shale time alignment curve and it will be fine if a person would sit 3 feet from the speaker. I highly doubt that anybody would sit closer then 15-120 feet from them – so it would not be a case. It is not to mention that if the owner have a complete discard to time alignment then he would put the Supertweeter in the very end of the horn and do not expose the Supertweeter to the ugly horizontal surface of bass horn. So, if this is a Supertweeter then I do not know then why it is positioned where it is. I would not be surprised if it turns out to be that it is disconnected. It might be the “former” tweeter or the tweeter that owner mounted and used and then when he went with JBL he does not want to remove “Tannoy Supertweeter” as it is already nicely mounted. I would understand THAT.
