Wavecor TW030WA09

Wavecor TW030WA09 frequency response & impedance (consisty)

TW030WA09_Amplitude_Impedanz

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 °)

TW030WA09_Winkel

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

The effects of the waveguide on the omnidirectional behavior are rather marginal.

Wavecor TW030WA09 Lingering behavior

TW030WA09_Ausschwingverhalten

Even and fast decay over all frequencies.

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

TW030WA09_Pegellinearität
Frequency response level corrected, based on the 85dB measurement

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

(Please note the scaling => 20dB-Range)

Wavecor TW030WA09 harmonic distortion

TW030WA09_Klirr

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.

Summary


The Wavecor TW030WA09 ...

With its XNUMXmm voice coil, a resonance frequency around XNUMXHz and the very low harmonic distortion already at XNUMXkHz it invites to be combined with a beautiful XNUMX midrange driver. In terms of measurements it has no weaknesses, is very deep (and loud) usable, looks classy, ​​and is, with an EIA of only XNUMX € (As of Dec. XNUMX) as very cheap. A high-end tweeter.
