Hey,

I'm looking into getting a JBL D130 8 ohm speaker with thoughts of using the power and preamp section of my pro with a 1x15 cab with the D130. The pro ('73) is rated at 4 ohms. But since it is running two speakers it's 8 ohms right? So will using just one 8ohm speaker through an extension cab work with this? I know it's been covered before, but not sure if I'm going in the right direction with my 4 ohm with two speakers is 8 ohms math.

Thanks!
