Thanks for the info. The reason I asked the question is because some “owners” and “magazine reviewers” have recommended the Y connectionmethod as far as the powered subs go. While others have not. The dealer recommends the simple speaker connection method, however, I was in the same dealership a few years ago and they were recommending the Y connection. (?) The LFE input on the speakers is “full range”. It takes whatever bass it wants and doesn’t pass along the other signals. Initially I am going to run just speaker cable and see what I think. As for the 950, I just wanted to make sure I wasn’t “limited” to the speaker cable only option. I believe I could run Y splitters from the 950’s L and R outputs, connect one end to the LFE and the other to the 750 or 770. Then from the amp with speaker cable to the mid connection (or even bi-wire to the high connection) of the speakers. Am I right, in this assumption?
