If you sum the signals from the sub and main you get +3 dB.(less after room interactions) If you cancel the signals with reverse polarity you get -40 dB. Much easier to hear! Method works best when the sub is close to the speakers. If sub farther away then differential distance from sub and main to different points in the room varies more, and result becomes more hit or miss. Then trial and error may be the best you can do. Maybe you are referring to Harley in Absolute Sound. http://www.theabsolutesound.com/articles/subwoofer-basics/?page=3
Subwoofers.... one 10" or two 8"?
I'm looking to fill out the bottom of my simple 2 channel system (Musical Fidelity X-Ray CDP through Peachtree Audio Grand Integrated amp to a pair of Mirage OMD-15 full range speakers). I occasionally will play the TV audio through the system for movies, but not interested in an HT setup. Music is the prime focus. The room is "medium" size. I know that will not give the deep bass feel of a 12", but the difference should not be too great, and a 12" may be overkill for that room. I've also considered getting two 8" subs to keep the sound balanced between the left and right channels. I think the 8" may be enough bottom for my room and tastes. I'm on a budget so getting a pair of anything bigger than 8" may not be in the cards.
Any opinions or suggestions as to whether I'd be better off with one 10" or two 8" subs?
