Review: A pesar de ser solo 10 watts rms, con una buena caja acústica funcionan muy bien. Elaboré una caja a la medida y realmente estoy sorprendido por el desempeño. Es algo pequeño, pero definitivamente funciona muy bien, buen rango de frecuencia de bajos, así que si no obtienes el resultado deseado en el audio, como siempre, es probable que se deba a tu caja. No esperes una gran potencia, son solo 10 watts rms y créeme que me ha dejado muy contento. He tenido subwoofer desde 15”, 12”, 8” y 6.5”, pero estos de 2” pulgadas realmente me han dado mucha satisfacción para mi escritorio.
Review: WOW fonctionne très bien
