Hi Mark, BP1Fanatic and Oliver,

The F6 functionality was actually introduced way back in Version 25.00 :-).

Hornresp

Itís just that I initially forgot to extend it to the R input parameter when the radius horn option was added :-).

Kind regards,

David

I'm not that oblivious to your improvements! :-)

As you pointed out it's been useful for quite a while.
But you just expanded it's scope of application.

Still worthy of a thanks you.

Speaking of Hornresp versions, I maintain a publicly available repository just in case.
If anybody else has been collecting them and wants to contribute any missing or prior versions please contact me via PM.

I was playing with HR tonight (very educational pass-time) and looking at various drivers in TL and BLH both with the driver 1/3 if the way down the line/horn. I noticed that with some drivers the active range from cut off to the first reflection was almost impossible to get linear. Usually it was a flattened "U" or "L" shape. IIRC these were all drivers with relatively high fs and Qts.

On a lark I added a throat chamber and lo and behold if I made the constriction of the throat chamber leading into the side of the horn section smaller than Sd (usually about 0.5Sd) that region smoothed out and the ripples above the first reflection were often reduced.

Does this behavior exist in real horns? And here is the question I hate to ask for fear that I won't understand the answer. What is the reason for this behavior?

Presumably if one wanted to do this the driver would have to be mounted basket out. If used only below say 80 or 100Hz would this still sound OK with the driver reversed?

Default Hornresp Update 3110-130216

Hi Everyone,

An anomaly in the operation of the 'Compare Captured' feature associated with the System Efficiency, Throat Sound Pressure, Throat Particle Velocity and Electrical Impedance Phase stand-alone charts has now been fixed.

My thanks to Djim for making me aware of the problem (via e-mail).

Kind regards,

David
