Amigos.
Tengo en mi poder 2 Parlantes Beyma 18" G50, mi intencion es hacer unos Sub Bajos, pero no se cuales, he leido de todo y no tengo claro que es lo mejor, si 2 separados o 1 con 2 parlantes. Como dato menciono que tengo 2 Cajas Peavey SP2 500 RMS, levantando con un amplificador XTI2000, para los sub tengo disponible un amplificador Crest cc2800 que lo usare en Stereo 8 Ohm o en Brigde 4 Ohm depende donde tenga que amplificar. (Amplifico musica en Vivo, Iglesia tanto dentro de ella como evento fuera de ella)
Baje el programa que me ayuda en las especificaciones de las cajas Winisd, pero va mas alla de mis capacidades de analisis :(
