Seas Noferro 900 (H 1025-06) Sound Pressure & Impedance (Scattering)

Seas Noferro 900 (H 1025-06) Sound Pressure Impedance Scattering

Excellent linearity. Full level already from 1000 Hertz. The efficiency is above average with 92 / 2,83V for an 25mm dome with a nominal impedance of 6Ω.

The amplitude, impedance and impedance paths of the two drivers are almost congruent.

Seas Noferro 900 (H 1025-06) Angle Measurements

Very clean and uniform bundling behavior.

Also in super high for a tweeter with 26mm voice coil very wide beam.

Seas Noferro 900 (H 1025-06) Lingering

Seas Noferro 900 (H 1025-06) Swinging out

Overall, very smooth and rapid decaying over all frequencies. Minimally delayed by 16kHz.

Seas Noferro 900 (H 1025-06) harmonic distortion

Seas Noferro 900 (H 1025-06) harmonic distortion

Very low distortion 3. Order. Even with 95dB / 1m always under 0,3% lasting, and that already starting from 1khz. K2 is heavily dependent on the excitation signal, rising below 3kHz. Recommended separation:> = 2kHz (18dB / octave) Overall very low distortion.

Summary


As a classic shows what he can.
In all disciplines, the Seas Noferro 900 shows very good readings.
Noteworthy are the ruler-smooth frequency response on the axis and the very clean omnidirectional behavior.
A really fine tweeter.
As already said the sound & sound (04 / 2000):

There's nothing wrong with this tweeter ...
