Origin

From Thorsten Felbingers pen (⇒Felbi.at) originated the concept, which, so to speak, "A perfect match"To my investigations in matters Baffle geometry, sloping chamfers & my measurements different Tweeter at Waveguide fits. It lacked only the means and opportunities to develop the passive crossover ... That's how easy win-win situations arise :).

Hi Alexander,

can you show a graph where the driver's phases (before, at the crossover point, and after) are displayed, as well as the drivers delay (as shown here https://heissmann-acoustics.de/en/dxt-mon-vs-neumann -kh-120a / # comment-485)?

Thanks in advance.

Cheers,

"The Disco-M, with its razor-flat frequency response and razor-sharp image, showed where the Barthel gets the must. Spatially excellent illustration also on the side of the sofa "

Impressions from the "Taxi Race" at the 10.03.2018 in Vienna

... not only my P / L winner, but also a LS, which I would immediately put into the living room, if I was not already very satisfactorily stocked.
not so full in the face at the first moment, but very relaxed, laid back, without lacking in dynamics or details anything.
sovereign easy.
...
The egg-laying woolly milchau pretty close to the discoM - even under angle barely losing any of its balance. loud and quiet simply a round thing for any music material.

(„nical“ im DIY HIFI forum)

little yellow cab vs. disco-M:

LYC: slightly center-stressed, unfortunately also quaerkiger. slight bloodless. on the one hand plays more superficially, but at the same time the playback is a bit more distant.
disco-M: a bodily, slightly longer-term vote. in the middle of the present, nevertheless more pleasant than at the LYC.

all in all, these two LSs are very close together when the volume is low, * the distance is significantly lower than expected * - the comparison of the previous compilation had to be expected otherwise.
except when it gets louder ...

("Lord of the Rings" in the Hifi-Forum)

Optically, the madness sets the Disco-M above all a vocal range before the unparalleled seeks. It sounds real, realistic and the voices are very fresh and fruity. Of course, music only sounds radiant and crisp if the recording pretends so, so the highlights are more likely to be in the middle than the highs. The bass is crisp but not particularly deep and neutral loud.

The speaker I'll build soon, I'm absolutely convinced of the thing! However, the Baumappe Felbi without his construction report is hardly to use, because a beautiful appearance as the Cinetor is missing and you hardly recognize anything on the inner model, especially the Erkentniss is missing where which bracing comes from and how the thick front wall is built! Also the material thicknesses are missing. It would be nice if there will be a further improvement. Otherwise, I'm very impressed, even from the switch!

mfg, Nils
