Hello!
not new to the forum but it is (weirdly enough) my first post here.
Ive been interested in horns and horn design for a long time now and ive been making progress on my hornresp skills.
The other day I picked up 4 pd.806 drivers (6,5") and i want to design a mid horn section for it for a 3way horn loaded top speaker (12" 6,5" 1")
Im running into some issues with the parameters though..
the driver is supposed to have a fairly flat (around 90dB/1w@1m) response from 150Hz to 5kHz
But im not seeing those frequencies at all when calculating designs and i suspect the driver parameters that are the problem.
on the datasheet it specifies MLSSA paramaters. and im having a hard time figuring out what to do with: L1, L2, R2, RMSE-load, RMSE-free
and therefore I doubt the current values I'm using for Le and Rms are the correct ones
I also added a screenshot of the driver parameters.
Perhaps they wont even be suitable for horn loading but I cant get it to simulate anything even close to the HF range..
anybody have any ideas about the deisgn for these drivers?
I'm thinking to put them in pairs loaded with a relatively short horn and possibly some kind of horizontal phase plug..
Again.. I have been reading and trying to design for years but never really got in touch with the community to solve my problems.. or confirm my methods for that matter
A lot can definitely be found but sometimes a (more specific to my issue) answer feels like the only solution
Looking forward to recieve some response and finally interacting with the community..
regards,

Are true horns beneficial for addressing shortcomings of making mid-range sound? Do horns introduce new shortcomings like poorer dispersion?
I really like the physics of horns (transformers of air resistance) as a concept with great value for subs, albeit at great cost and effort.
