Here are 2 alinks to articles on placement that I found helpful:

and

The best setup, of course, would be 2 of the 2Wq subs in a stereo redirected bass setup and 1 of the V2W for LFE only.

If you run the analog SW out of the player for LFE only (using the player's DACs), when you switch to digital (the pre's DACs), the LFE will be inserted into the 2Wq sub or subs as well as the LFE sub, equalling a 6ish dB boost for flicks.

I forget what pre you have (MC-8 if memory isn't totally fried)??

The info you linked is a bit confusing, in that it describes the 2Wq as 'second order, slot loaded' and having adjustable 'Q' from .5 to 1.2. Hmmmmmm...second order is a sealed design, whereas slot loaded is a 4th order ported design which would make 'Q' adjustment over that much of a range difficult.

Maybe you can help me with V's terminology.
