Les comento que tengo este receiver sony STR-DE675 y un sistema de parlantes satelitales sony (2 parlantes frontales, 2 parlantes envolventes, 1 central y un subwofer).
mi idea es cambiar los 2 parlantes frontales por parlantes de mejor calidad para escuchar la musica de mi ps3 de mejor forma, siempre respetando el tamaño osea pequeños.
ej:bose, jbl, etc.

pregunta

1-Se puede comprar solamente el par frontales?
2-Que marcas me recomiendan?
3-Que precios de referencia manejan?
4-Dara buen resultado cambiar solamente los frontales o tecnicamente sonaran igual a los sony?
