I have no idea what he is and what he is looking for. He declares himself as “just an average guy in an average basement shop building hi-fi audio horn speakers from wood”. I do not even know in what country his leaves, not that it is important. He has a site and a blog:
Anyhow, he looks like recently made a new installation.
Let see what it is. The playback has 38 Hz tapped horn, 100 Hz Multi-Sided Conical Exponential Horns with unknown drivers, the 320 Hz Round Tractrix Horns with JBL 2446 and some kind of tweeters. It looks an attempt was make to time-alight then in frame – a good sign. The author is concentrated on the wood crafting and provides no information about sound of the thing, crossovering and anything else. The horns are not positioned properly; most likely they are not even connected and juts too fresh.From what I see the MF horn might be too high. It is hard to judge as it is not known what the eyes level on the picture is. The Midbass looks like as good idea, but I would go for not even amount of sides. The back chamber look like too big but it might be made this way intentionally in order to be a base for the rest of the frame. It would be very interesting to hear how the tapped horn sound – never heard them….
