Waveguides and horns

[Tytte71]

Thanks! ... wonder if the non linear tendencies in the impedance measurement have major impact in time domain.

OS-12 with DE500 power averaged response in ARTA and same data analysed in dr. Geddes application - power response is red, white is DI. Pictures of SEOS-10 Frontpanel exhibited at Hi-End Munich 2012.

Slightly better picture of Universe 2012 prototype (Radian 950 + Truextent, active Eminence Delta 15A).

Hi Lukazs

where did you find those measurements?
(I am using 4001 and your/JMLC iwatas)

Hello,

Despite Earl's unfair words and even if I am not the one who performed the measurements I am really certain that many people will appreciate at least the smoothness of the (unequalized !) frequency response of the TD4001 + Iwata 300 couple and the most excellent performance in distortion (H2 curve = replica of the FR curve: no peak of distortion near the frequency cut-off....) that no OS waveguide will ever offer (and lead someone to try desesperately to prove that distortion doesn't matter, when audiophiles ears every day prove the inverse...).

You'll find here attached an measurement (unequalized) I used to perform at 1 meter from the mouth of a Radian 760Neo on an Iwata 300 belonging to a friend. For sure the quality of the Radian 760Neo is not the same as the TAD TD4001.
