Hola soy amante de la musica y deseo armar unas cabinas mas amplificador y quisiera su opinion al respecto

la idea es armar un par de cabinas con 4 parlantes

PEAVEY PRO 15 RAW SPEAKER

15" 8 OHM LOW FREQUENCY DRIVER

15" woofer with 2.5" voice coil
800 watt peak
400 watt program
200 watt continous
8 ohm impedance
96.4 db / 1w 1m
40hz - 3khz
Kevlar impregnated cone

Y CADA UNA CON UN DRIVER Selenium D220Ti 8 ohm Horn Driver Pair New With Horns!

con lo poco que he leido y me he empapado del tema me es suficiente para comenzar con mi idea tener un buen sonido que me sirva para fiestas familiares y por el estilo

me falta definir si ponerles crossover pasivo o activo (aunque este tema no lo tengo bien claro) pero he leido que es mejor utilizar uno activo que permite el control de las diferentes frecuencias para cada rango.

tengo visto este Eq marca Beheringer

ademas la gran duda es que amplificador o mss bien de que vatiaje necesito teniendo en cuenta que quiero que me sobre potencia y no quedar ajustado,


para el amplificador tengo un prespuesto de aprox 350 dolares
gracias

Necesitarias un amplificador de al menos 450 watts rms a 8 ohms por canal para alimentar los 2 wofers ya que estos son de 200w rms cada uno.
