Measurements in DIN baffle in 70cm distance at 2,83V. Level scaled to 1m
Vifa XT-300 (XT25TG-30 / 04)An extraordinary tweeter, equipped with a 5mm thick front panel, a 5-hole attachment and a "bead only design" as a membrane.

Vifa XT-300 (XT25TG3004) Frequency response and impedance response

Outstanding linear frequency response. Full level from 1,3kHz. Extremely good-natured "roll-off". The efficiency is on average 91,5dB / 2,83V. One copy has a resonance frequency that is 20% higher, but this has no effect in the intended working range. Otherwise congruent course from 1,5 kHz. Very well. At the frequency response you have to look very closely to see whether there are 2 or 3 drivers. Practically congruent course from 600Hz.

Vlt. a little note at this point:

I do not buy any preselected drivers ... With such a result, one might suspect that.

Vifa Peerless XT-300 (XT25TG3004) Angle Measurements

Very uniform omnidirectional behavior. Somewhat stronger directivity than with 25mm calottes. No criticisms. Recommendation: Tuning linearly to 15 °.

Gray line: 1%

Outstandingly low 3rd order distortion. From 1,5kHz <0,1% at all measured levels. The "good-natured" K2 rises relatively sharply below 3kHz. A little bit of "whitening" is built in. In the case of separations> = 2kHz, K2 should still remain below the perceptibility threshold, even at very high levels.

The ring emitter Vifa / Peerless XT-300 K4 (XT25TG-30 / 04) is outstanding in the sum of its properties!

The frequency response is linearly smooth, the omnidirectional response is extremely even and the decay behavior could not be better.

The ring emitter can be used in very level-stable combinations from 2kHz. With "normal" level requirements also lower.

Series spread seems a foreign word for the driver. Furthermore, its intended working range is far outside the region around the resonance frequency that is prone to series fluctuations due to the design of tweeters. It is generally not recommended to separate tweeters> = 2x FR for nothing.

and the whole thing for extremely inexpensive 47 € (RRP) ...

I have installed the XT-300 K / 4 with the SPH-175HQ in the kit Samuel HQ, and I am very pleased with its features.
