Hi everyone, I've got a pair of a/d/s/ AVT-148 speakers. They're 3-way tower with a 8" woofer, 2x 4" cone midranges and a 1" tweeter per cabinet. The midranges and tweeter are aligned in MTM configuration. I was surprised when I opened up the crossover network. I found that the two midranges, in the same cabinet, are wired out of phase to each other and with series wiring. Each driver is 4 ohms. So, they are 8 ohms for midrange section. I remove the crossover to use with an 8-ohm driver. They sounds normal. Nothing abnormal as unexpected. Please tell me what is the purpose of wiring the midranges out of phase? Thank you in advance.
How do you know they have opposite polarity?
I think that they have the same polarity just with a series connection.
The negative terminals of each driver are connected together. And the positive terminals of each driver are connected to positive and negative terminals of crossover network.
