What do people think? Are these designs worth pursuing? As in, can it be improved much more?
Compression (area of horn at throat entry vs Sd) looks a little high. I tend to aim for values lower than 4 with these drivers.
Caution: I don't think HornResp includes losses in its modelling. What looks flat in the same might not end up being flat when you measure it. Rolloff might end up being higher and faster than predicted, for example. On the plus side, the response is likely to be smoother than predicted.
You mean the ratio hornresp shows when I put the mouse over S2? I have done a bit research there and apparently jbell has tried using a compression ratio up to 8:1 and its fine for these particular drivers. But I maybe wrong.
Have you ever tried the 8:1 without a compression chamber? And what size do you use?
