i'm setting up my first system today and wondering how to wire the subwoofer out terminal for the .1 in home theater using the powered ten inch subwoofer in both of my floorstanding def techs? thanks for any help.
You can use a quality Y-adapter to split the .1 output to the LFE low-level-in on the Def Techs. Use a good quality sub cable on each. With this configuration you will be able to use the bass management on your receiver and bypass the Def Tech's sub crossover, OR use the crossover controls on your Def Techs OR a combo of both.
You can also run the speakers with regular speaker wire only, and the subs will take the low frequencies from that. However, running separate sub cables for the LFE channel is clearly the best setup.
