Yeah, but this horn has no appreciable T/S parameters to speak of (Lowthers with "off-the-chart" numbers) and they do not operate near any resonant cutoff frequency because the horn cuts it off before the driver does.

So a lot of high frequency horns are like this, which is also a lot like tweeters. Tweeters are not designed with Qts in mind when crossed over well clear and above where Qts takes effect. And that's why it's still okay to use series resistors in tweeters and midrange drivers for attenuation purposes and still have good transient behavior.

So I don't know exactly how series resistance is playing the only role in INCREASING the damping down of this horn that controls the cone better and allows more detail to pass through at middle and high frequencies. According to this argument the opposite if anything should have happened. It "should" have gotten more sloppy and less distinct, but then again Qts is not a factor really.
