Coaxial drivers have their own merits.
In fact, two way systems even with proper room treatment still have a big issue: they force you to be with tweeter at ear level to enjoy that pretty nice frequency response we see in measurements..pros and cons
That doesn't really replicate a coaxial as you can see from the vertical off axis response.I do notice that the drivers appear to placed as close together as possible to the degree of having to cut out part of the woofer' trim piece.
Maybe please also add at which SPL or voltage?Thanks. Corrected and added distortion graph.
It is 10 volt input.Maybe please also add at which SPL or voltage?
The S400 finally arrived so I can do that.A comparison with the Buchardt S400 would be really interesting. Wide versus narrow dispersion.
And also temporally..in fact, as a consequence, they won’t be aligned in time..a square wave, just to say, will be ok at ear level but will be smeared just slightly off axis..I asked once Sean Olive, but he says there are not evidences of people being able to detect group delays...That doesn't really replicate a coaxial as you can see from the vertical off axis response.

So a real bookshelf speaker showed up. Nice review. The eq guys won't like it.
It seems to be the normal behavior of paper coated/aramid woofers of about 6 inches of diameter. Just look for example on the Seas website..the driver supplierAnd as Andrew Jones has said before, he sometimes optimizes for slightly off axis. This is evident from the graphs: the speaker is significantly better at 20 degrees off axis, which I often find is the case with KEF speakers as well.

Weird that so many speakers seem to have a bump from 600-1000Hz ish
Thanks another great acoustic review.....Speaker Listening Tests.....Ah, what joy!...
