I play in a three peace band with a singer I am using two Yamaha club 15s on poles and a powered mixer when we play live in small clubs i have a hard time hearing the bass player on the other side of the drums when we have a good mix.what do i need to look for in monitors that are affordable that i can run the bass through to give us a thicker mix on stage and i can hear him over the drums clear. having only a guitar and bass he is so important to me so i can stay where i need to be.
