Peerless_XT19_XT200_Amp_Imp_a_b

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

Full level from 1,2kHz. Extremely good-natured "roll-off". The efficiency is rather below average on average 89,5dB / 2,83V. For most applications but 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.

Outstanding low distortion 3.order. From 2kHz at all measured levels <0,1%. The "good-natured" K2 increases relatively strong under 3kHz. A bit of "beautification" is thus built in. Clutter components of higher order are practically not apparent. For very level-fixed combinations, I recommend separations from 3kHz. Smaller 2-Weger (eg with a 4 "TMT) may already be separated by 2kHz.

Summary


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 in appearance but also in all measurements. (The resourceful reader will have noticed that a few passages are identical in both tests ...)

The frequency response is linear smooth. Can be used in very level feast combinations from 3kHz otherwise like deeper. Series dispersion seems to be a foreign word for the driver. Furthermore, his intended work area is far outside the design of tweeters, prone to series fluctuations region around the resonant frequency. It is usually not recommended in vain tweeter> = 2x FR to separate. Extremely laudable.

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 average with 91,5dB / 2,83V on average. A copy has a higher resonance frequency by 20%, but this does not affect the intended workspace. Otherwise from 1,5kHz congruent course. Very good. With frequency response, you have to look very closely to see if they are 2 or 3 drivers. Practically congruent course from 600Hz.

Vlt. a little note at this point:

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

Summary


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 low-level combinations from 2kHz. At "normal" level requirements also lower.

Series dispersion seems to be a foreign word for the driver. Furthermore, his intended work area is far outside the design of tweeters, prone to series fluctuations region around the resonant frequency. It is usually not recommended in vain tweeter> = 2x FR to separate.

Vifa XT-25 / Neo4 (XT25SC90-04) Frequency Response (Scatter)

Good linearity. Full level already from 0,9kHz!

With 91,5dB / 2,83V, the efficiency is average for an 4Ohm driver and sufficient for 95% of all applications.

With 4khz there is an impurity, which also shows in the impedance response, but not in the decay behavior. With clever wiring of the Peerless XT-25 / Neo4 you can "magic out" of the elevation an 2dB sink to 3,5kHz, which is usually perceived as very pleasant. D

The amplitude responses of the two drivers are practically congruent. Very good

The 830Hz resonant tip of the ring radiator shows that no ferrofluid was used. A minimal disturbance can be seen in 4kHz, which also shows in the amplitude response. The impedance paths of the measured drivers are congruent. Exemplary.

Due to its large diaphragm (30mm diameter) the ring radiator straightens more than 25mm calottes, but very evenly. Many Tüfftler appreciate this property when coupling the Peerless XT-25 / Neo4 to a waveguide.

K3 is extremely low until 2kHz, including steeply rising. K2 is already increasing even under 3kHz. A separation at 2kHz but in my opinion nothing stands in the way. In combination with two 5 "drivers, I have already disconnected at 1,7kHz and the dome does that without any problems. K2 barely scratched the 1% brand. Overall, really good values.

Summary


Level fixed small tweeter which is very universally applicable.

Due to the large membrane, it can be very loud and can be used from 2kHz.

Due to its "special" directivity, the ring emitter is very well suited to be combined with a waveguide (eg WG-300 from Monacor). Then the distortion sinks below 2kHz and a separation around 1,5khz is nothing in the way.

Predestined is the Peerless XT-25 / Neo4 for d'appolito, - and all other arrangements in confined spaces.

To emphasize is the very small dispersion. The two measured specimens of the ring radiator are practically congruent both in amplitude and impedance.
