it in mágicos own spinsSure, whatever...
My, my, sins of ommision. Pathetic.With FR sins of omission (dips, roll-offs) are much less objectionable to me. I think the signature is deliberate to make it inoffensive across a broad range of rooms, especially bad placement in a bad room (e.g. lots of glass, not unheard of with the clientele). And honestly, for 5-6k more than a Revel 328, I'll take this for fuzzy feelings of entering the big boy ultra-high-end club, the machined enclosure and US production.
Pretty sure the tweeter dropping above 7000Hz is an intentional thing that Magico...
This is how a true pistonic dome behaves. It's physics. If you see a 1" dome extend at full efficiency above10K, it mainly contained rubbish.
Then Magico should update their website, because that's where I got the image detail that shows a clear step to control and increase the top high frequency range, along with the entire waveguide.I can assure you, there is no such step on the tweeter faceplate, just like there is no "drop like a rock" response @7K
In the sectional view of the tweeter, it looks like its step (with a slightly rounded edge). The step is usually 2-4mm and controls the radiation in the uppermost tweeter range and raises the frequency response on axis - as shown in the simulation.It is not a step, it is (clearly) a radius.

A tweeter that works completely without any "directivity/sound control" (no step, waveguide,...) would be for example the Bliesma T34B-4 34mm:

The tweeter of the Magico series has a flat waveguide after the first step - which I do not show here.
If you have a picture that shows otherwise, bring it on - no one (especially me) wants to make false statements here in the thread.
At least the step on the tweeter's front panel was still there when Stereophile wrote their review. The flat waveguide is difficult to see.In the picture on their site, it's quite clear that it has such a step. Maybe that's an old photo that on their site?
Wow. $25k and they couldn't even make the speaker go up to 20khz. As usual, everyone is amazed at the "smooth directivity," seeming to forget that that frequency response is far more important.
But the top octave (10 to 20kHz) is probably the least important octave for frequency response errors.
SINCE WHEN?
It actually goes up to 50K. Read the part about pistonic domes

Which octave would you consider less important? 10-20Hz? 20-30Hz?
I would think that 10-20kHz probably is one of the least important octaves. I believe that Geddes talks about how in his research people actually preferred some level of downward tilt above 8-10kHz or so.
