In our Sadurni Acoustics horns we use different drivers, selected for their sound at that frequency, we use the driver that sounded best, cost no object! If it didn´t exist, we had it made for us!
The midrange "turbine" horn uses a compression driver.
The Upper Bass Horn uses a dynamic/cone woofer implemented in such a way, as described earlier, that the response is 110 dB.
All XOvers are first order.
The turbine horn is shaped that way so that the sound coming form the tweeter wouldnt hit the back side of a traditional horn and cause imaging difussion. With the "turbine" profile, high frequencies, slide through the sides and allow us to get pin point imaging.
The size of the turbine horn is the porper size for the frequency it is handling, it is a Tactrix profile that allows for very close range listening (which I personally love). For the frequencies it is designed for, it loads the lower portion of the range perfectly, a Little bigger and the response would go lower, thus invading the range of the upper bass horn causing doubling of the sound and posible distortion. It is small enough so that the higher frequencies, at the range we want it to play at, can make it out of the horn. Making a longer horn causes rapid decay of higher frequencies.
We wanted the midrange to be played by one driver for the longest range posible, this gives us a better coherence in sound and imaging. The supertweeters come in at around 10 kHz.
If we used a different profile, for example: LeCLeach, it would be a much bigger horn, we tried it and liked the sound of Tactrix better.
