PSI Active Bass Trap
Las conclusiones finales "a oído" conmutando On/Off el AVAA, es decir sólo cambiando el AVAA encendido/apagado:
"You can also see that i have bass traps and EQ, and still how much the PSI brought improvement to the set up 20-40hz range. In fact you dont need the tools, you can hear for yourself. On off, repeat scene, on off listen few times, you can hear clearly how it sounds. Much tighter, controlled, clean sounding and pleasing."
