Heissmann Acoustics | Test Peerless XT19TD00-04 (Vifa XT-200 K4)

Measurements in DIN baffle in 70cm distance at 2,83V. Level scaled to 1m

19mm ring radiator from Peerless, distributed by Quint-Audio. Equipped with a 4mm front plate, a 4-hole attachment, a "bead only design" as a membrane, a coupling volume and excellent measured values ...

Vifa / Peerless XT19TD00-04 (XT-200 K4) sound pressure & impedance (dispersion)

Outstanding linear frequency response. From 2,5-14kHz + -0,5dB!

Full level from 1,2kHz. Extremely good-natured "roll-off". With an average of 89,5dB / 2,83V, the efficiency is rather below average. For most applications, however, completely sufficient.

Outstanding pair equality in the two measured copies both in impedance, - and amplitude response. The maximum deviation of both drivers> 500 Hertz is + -0,15dB! This testifies to an excellent production consistency.

Thanks coupling volume very low resonance frequency around 750Hz. The impedance peaks indicate a dose of low-viscosity ferrofluid. Their slightly different characteristics are completely meaningless, being far out of the usable range.

Vifa / Peerless XT19TD00-04 (XT-200 K4) Sound pressure at angles (15 °, 30 °, 45 °, 60 °)

Extremely consistent and a 19mm voice coil corresponding Rundstrahlverhalten.Idealer game partner for broad-beam concepts. Also interesting would be the ring emitter a very small baffle (similar Samira) to provide a uniform directivity to the TMT / MT.

Vifa / Peerless XT19TD00-04 (XT-200 K4) Decay behavior

Very smooth and fast decay over all frequencies.

Vifa / Peerless XT19TD00-04 (XT-200 K4) harmonic distortion

Vifa Peerless_XT19_XT200_Circle — gray line: 1% distortion
Graph switches every 3 seconds

Outstanding low distortion 3.order. From 2kHz at all measured levels <0,1%. The "good-natured" K2 increases relatively sharply below 3kHz. A little bit of "enhancement" is built in. Higher order distortion components are practically not apparent. For very level-stable combinations, I recommend separations from 3kHz. Smaller 2-way (e.g. with a 4 ″ TMT) can be separated by 2kHz.

Conclusion

The 19mm ring emitter Vifa / Peerless XT19TD00-04 (XT-200 K4) measured in the sum of its properties absolutely outstanding!

The relationship to his big brother, the XT25TG30-04 shows not only on the outside but also in all measurements. (The resourceful reader will have noticed that a few passages in the text are identical in both tests ...)

The frequency response is linearly smooth. Can be used in very level-stable combinations from 3kHz, otherwise 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. Extremely commendable.

and the whole thing for extremely inexpensive 45 € (RRP) ...
