All who have replied, I thank you for sharing your thoughts. imhififan, I like the idea of shielded power cords to the sub amps if they are onboard the speakers. Didn't realize that this was a possibility until you mentioned this. Looking on Amazon and other vendors, it looks like these can be inexpensively obtained. Have also noted that there are shielded subwoofer line level output cables as well that are inexpensive.
almarg, to answer your question. I think that the following are the likely scenarios that are framing up in my mind based on the received responses: (As background the speakers being built for me Are Ohm Acoustics F-5015s and the stereo receivers that fit my furniture under consideration are the NAD M32 and the Parasound Halo INT6. I will likely use Blue Jean Cables for the speaker cable runs and line level output cable runs.)
Scenario 1 - a subwoofer amp onboard each main speaker: Use a shielded power cord to the subwoofer amp. Use a speaker cable from the stereo receiver with speaker level outputs to attach to the main driver in each speaker. Use a line level output shielded subwoofer cable from the receiver to each subwoofer amp in the speakers. The power cord, speaker cable and line level cable would run parallel to each other to the speakers.
Scenario 2 - a subwoofer amp outside my speakers positioned near the stereo receiver. Small length line level connections to the subwoofer amp. Separate speaker cable with speaker level output from the subwoofer amp to the subwoofer in each speaker. Separate speaker cable with speaker level output from the receiver to the main drivers in each speaker. Both speaker cables would run parallel to each other to the speakers.
almarq, thanks for the thought on the potential vibration issue for the onboard subwoofer amplifier option. I will need to ask this question of Ohm Acoustics.
roberjerman, thanks for the thought on the ease of adjusting the receiver and sub amp if they are in a similar location. This is a definitely something to consider.
If any of you have any more feedback on this series of questions and Scenario 1 and Scenario 2, please provide your thoughts.
