Wavecor TW030WA09

Wavecor TW030WA09 frequency response & impedance (consisty)


Very good linearity with evenly decreasing amplitude response. Extremely broadband. The efficiency is on average around 93dB / 2,83V. In the super highs, however, only to 88-90dB.

Both drivers are practically congruent in their frequency response up to 10kHz. Above very small deviations. Very good. The TW030WA09 is expressly advertised as "... best consistency" in the manufacturer data sheet.

There are no disturbances in the impedance. Practically congruent graph of both drivers. Exemplary.

The resonance frequency is at 700Hz. Very low for a driver without coupling volume. The accented resonance peak indicates that there should no ferrofluid be found in the air gap.

 Wavecor TW030WA09 sound pressure at angles (15 °, 30 °, 45 °, 60 °)


Very even and balanced omnidirectional behavior. For a tweeter equipped with a 30mm voice coil even in the super high tones still widely radiating.

Wavecor TW030WA09 decay behavior


Very even and fast decay over all frequencies.

Wavecor TW030WA09 level linearity 85, 90, 95 and 100dB

Frequency response level corrected, based on the 85dB measurement

From 100dB minimum dynamic compression <= 0,5dB in the super high tone.

(Please note the scaling => 20dB range)

Wavecor TW030WA09 harmonic distortion


Very low harmonic distortion even with 100dB. K2 increases evenly with the level, hardly exceeding the 100% mark even with the 1dB measurement.

K3 and higher-order distortions play virtually no role. One might be tempted to separate the tweeter with a steep edge at 1200Hz. Who wants to be safe takes 1,5kHz.

The Wavecor TW030WA09 ...

with its 30mm voice coil, a resonant frequency around 700Hz and the very low harmonic distortion already from 1kHz invites you to be married to a beautiful 20 midrange driver. Messtechnisch he makes no weaknesses, is very deep, looks classy, ​​and is, with an EIA of only 55€ (As of Dec. 2013) to be described as extremely cheap.
