I have modified my DIY 2-way speaker to 3-way. The old 2-way system consists of a 6.5" woofer, SEAS H602, and a 1" tweeter, SEAS H400. Crossover network is an ordinary 2nd order. I added a passive subwoofer into each speaker to convert it to 3-way system. The sub is a 7" driver bandpass cabinet. They get along well with each other. But sometimes I think the sensitivity of sub is lower than the sat. So what if I added some potentiometers or attenuators to the sat in order to compensate for the sub? Any ideas?
