T2030                                                                                         -Studio-
HIGH
FREQUENCY
This metal dome tweeter is designed for high frequency reproduction in two or three way studio or domestic systems. It features an aluminium
diaphragm, an especially designed cast aluminium front plate and phase plug, to achieve flat frequency response, high efficiency, and wide and
controlled dispersion pattern.
Tweeter con cupula metalica que permite una reproduccion del extremo agudo con una gran precision y fineza. Tanto su sensibilidad como su
respuesta transitoria son inmejorables, y permiten una gran polivalencia con sistemas miniatura hasta modelos semi-profesionales.

NOTES
*The power capacity corresponds to the RMS maximum value that
can dissipate the loudspeaker when a sinus signal is applied for a
period of at lest two hours.
Program power is defined as the transducer’s ability to handle normal
music program material.
**Sensitivity was measured at 1m distance, on axis, with 1w input,
averaged in the range 2-15 kHz.
*** T-S parameters are measured after an exercise period using a
preconditioning power test, using a velocity-current laser transducer,
and will reflect the long term parameters, once the loudspeaker has
been working for a short period of time.
****The polar plots are reproduction of measurements done with single
sinusoidal signal tones, at the indicated frequencies. Rotation was  FREQUENCY RESPONSE, PHASE. On axis, 1w @ 1m.  FREE AIR IMPEDANCE CURVE

NOTAS
* La potencia admisible corresponde a la maxima potencia RMS que
puede disipar el altavoz durante al menos dos horas, cuando se le
aplica una senal determinada. Por potencia programa se entiende la
capacidad de altavoz en el manejo de senales transitorias como seria
el proporcionado por el contenido de un pasaje musical normal.
**Medicion realizada con el microfono a 1 m de distancia, en el eje,
aplicando 1w al altavoz, promediando en el rango 2-15 kHz.
***Los parametros T-S han sido medidos despues de un periodo de
fatiga y estabilizacion de las suspensiones, mediante transductor laser
de velocidad-corriente, y son el reflejo de los parametros a largo plazo
del altavoz, una vez este haya sido instalado y haya trabajado en un
corto espacio de tiempo.
****Los graficos polares fueron medidos con el tweeter situado sobre
una mesa giratoria, sin pantalla, con el foco emisor sobre el eje de
giro y situando el microfono de medida a 2m. de distancia de dicho
eje. Las senales usadas son tonos puros de las frecuencias representadas.
