Tomorrow I will receive a Kenwood 7070A receiver from Crutchfield for a H/T setup. Audes Souls will be used as front R/L, 8 ohm speakers. Audes makes a center speaker (The Sentral) but it is rated at 4 ohms. The Kenwood is rated for 8-16 ohm speakers, but I was wondering if it was possible to use the 4 ohm center with 8 ohm surrounds? Will this cause a volume mismatch between the 4 ohm and 8 ohm loads?
