A German company Avatar Acoustics makes loudspeakers with adjustable positioning of their ribbon-tweeter. This is very much with the context of this thread although I’m questioning a lot of things in those loudspeakers (pretty much everything beside the DESIRE to have adjustable tweeters). The Avatar Acoustics suggest that they did it for “time Alignment for the listener's position”. Since they clamed that they implemented the phase-linear crossover their desire to fine-tune the tweeter’s distance looks like a noble task, at least at surface. However, if to look deeper then for the given design it is PERFECTLY POSSIBLE to set the correct location of the tweeter and do not move it. The “perfect” poisoning of the tweeter might very slightly fluctuates depends of the elevation of the listener’s position but in real world the delta of the position would be within a fraction of an inch but not within a whole 12 inches as the Avatar Acoustics suggests (even considering the low crossover point). Unless the Avatar people propose to move the tweeter console in the real time when a person is walking around the room?!

Anyhow, I do not feel that the time adjustability was is really necessary in the GIVEN design (12 inches!!!). It is like a tonearm with adjustable azimuth of the tonearm wand: completely unnecessary and crates more problems then helps (unless you are wiling to play defective cartridges).
