Frequency response and impedance (consisty)

Test Monacor DT-101SK

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

The impedance path scatters, especially around the resonant frequency a little more. A slight disturbance shows up at 2,3kHz. However, this shows neither in the decay behavior nor in the sound and can be considered harmless.

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

The scatter of the measured copies is at 1kHz + -5dB, at 3kHz + -3,5db, it gets a bit better. The resonance frequency varies between 1,1 and 1,8kHz. None of the specimens is nearly as linear as the first 3 measured.

For at least 3 of the measured specimens it can be assumed that the voice coils are decentralized to the extent that they "pinch" one-sidedly.

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

Test Monacor DT-101SK

Very uniform omnidirectional behavior. For a 25mm dome very far reaching frequency response. No criticisms.

Monacor DT-101SK decay behavior

Smooth and fast decay, slightly delayed by 10 and 15kHz.

Monacor DT-101SK harmonic distortion

Test Monacor DT-101SK
Gray line equals 1%

The harmonic distortions are very low. K3 remains below 900% at all measured levels starting at 1Hz. From 1,2kHz even under 0,3%. K2 rises evenly with the level and always stays at a very low level. Clinker components of higher order are completely negligible.

Summary


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

He is very broadband applicable. A lower crossover frequency of 1,5kHz is quite feasible, depending on the concept and level requirements. The omnidirectional behavior is impeccable. Touching quality and workmanship are good, the harmonic distortion very good.

And the whole thing for cheap 33,90 € (RRP)

Addendum:

There are, at least for one of the measured batches, significant problems in terms of manufacturing consistency
