Hi all, I'm considering one of these two, but I'm not sure how they compare. From a placement point of view the 31" would be hidden behind an armchair in the corner, whereas the 39" will be poking it's head over the top of the chair, and I'm not sure what the wife will think of that. The SVS website seems to suggest the 31" goes louder, but not as low, but I'm not too concerned with playing stuff really loud, so would I be able to tune a 31" to go lower and not really suffer any drawbacks if I'm not listening at reference levels? As always, opinions/comments gratefully received! Cheers, Ed.
