12B100/R
LOW
FREQUENCY
The 12 B100/R is a high compliance, bass loudspeaker, featuring wide, single polyurethane foam roll, a 4” voice coil diameter, and a massive, powerful
magnet system. These ensure excellent efficiency and extended low frequency response. This model has been designed for use in bass-reflex or
closed enclosures, in high quality multi-way systems.
Este altavoz de 12” de alta elasticidad, disenado para aplicaciones de subwoofer o de graves, esta dotado de una suspension de espuma de media
cana que le permite una elongacion importante, y bobina de 4” de hilo plano movida por un circuito magnetico de gran tamano que le asegura
una amplia respuesta en frecuencia con unos bajos profundos y contundentes. Disenado para una utilizacion en recintos bass-reflex de sistemas
de gran calidad.

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 least two hours.
Program power is defined as the transducer’s ability to handle normal
music program material.
** 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.
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 senoidal determinada.
Por potencia programa se entiende la capacidad del altavoz en el
manejo de senales transitorias, como seria el proporcionado por el
contenido de un pasaje musical normal.
* *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.
