I got in touch with SVS and they suggested not mixing high level and line level. That we all can agree on:))
I will get a measurement mic in next couple of months or so and measure these things for my own learning and also for fun. I want to place the subs in their optimal location in the room - not necessarily symmetrically inside or outside of the main speakers. Nothing wrong with the symmetrical positioning though. Aesthetically they look really nice. Right now they are outside of the main speakers.
I am also planning to do a DSP based crossover to distribute low frequency, say 50 - 60 Hz, to the dual subs. I used to have external 80 Hz high pass filter with my large bookshelf speakers and the dual sub crossover set appropriately. I really liked the sound. The imaging and soundstage were great. I had a pair of Maggies with the same set up. Now I have a pair of Thiel CS2.4 (and I am already looking for CS3.7 or 7.2 model ...... my never ending itch for upgrades - sigh) that go down to mid 30s, I guess. Adequate for most music I listen to. I still want the occasional 20 Hz bass if it is present in the music, as I like to feel that bass more than I hear it :))) Heck at some point I will go for distributed bass array with 4 subwoofers! My room is a dedicated listening room, 17 X 24 ft in size. So I got space for that.
