Seas Prestige Noferro 900 (H 1025-06)27mm dome tweeter 6 ohm |
|||||||||||||
Seas Noferro 900 (H 1025-06) Sound pressure & impedance (dispersion) |
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) sound pressure at angles (15 °, 30 °, 45 °, 60 °) |
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) decay behavior |
Overall, very smooth and rapid decaying over all frequencies. Minimally delayed by 16kHz. | ||||||||||||
Seas Noferro 900 (H 1025-06) harmonic distortion |
Very low 3rd order distortion. Even at 95dB / 1m it always stays below 0,3%, and that from 1khz. K2 is strongly dependent on the excitation signal, rising below 3kHz. Recommended separation:> = 2kHz (18dB / octave) Overall very low distortion. | ||||||||||||

Has this tweeter been discontinued?
Do you think the Seas 27TFF would you like to have a similar response?
Unfortunately I cannot answer your question ... have a try. Its not a very expensive tweeter!
Best regards
