Frequency response and impedance (consisty)

Test Monacor DT-101SK
Good linearity. Almost full level already from 1,1kHz. The efficiency is, with an average of 92dB / 2,83V, above average. All 3 drivers are almost congruent in their amplitude response. Very good.

The impedance response scatters a little more, especially around the resonance frequency. There is a slight interference around 2,3 kHz. This is also evident in the amplitude frequency response with a slight dip.

Unfortunately, when measuring 7 new specimens have a very unpleasant picture.

The spread of the measured specimens is considerable and amounts to + -1dB at 5kHz, + -3db at 3,5kHz, above this it gets a little better. The resonance frequency varies between 1,1 and 1,8 kHz. None of the specimens is nearly as linear as the first 3 measured.

With at least 3 of the measured specimens, it can be assumed that the voice coils are decantral to such an extent that they “clamp” on one side.

The black curve is one of the three first measured DT-101SK and thus serves as a reference.

Quite even omnidirectional behavior. For a 25mm dome, the frequency response goes up very far. No points of criticism.

Monacor DT-101SK decay behavior

Even and fast swinging out.

Monacor DT-101SK harmonic distortion

Gray line equals 1%

The harmonic distortion is low. K3 remains below 900% at all measured levels from 1Hz. From 1,2 kHz even below 0,3%. K2 rises evenly with the level and always remains at a very low level. Higher order distortion components are completely negligible.

The Monacor DT-101SK measures itself well in all respects.

It is very broadband applicable. A lower crossover frequency of 1,5 kHz is definitely feasible, depending on the concept and level requirements. The omnidirectional behavior is equivalent to a 25mm dome without sound guide. The touch quality and workmanship are okay, the harmonic distortion is low.

There are, at least with one of the measured batches, considerable problems in terms of manufacturing consistency.
