I bought a pair of 10E subs for my stereo listening room. This is music only, so I wanted to emphasize the soundstage and bring in lows that my tower speakers couldn't do. The room is a rectangle, 2040 cubic feet with 8' ceilings. Musicality is my emphasis and I listen to many musical genres. I don't care about flashy and neither do I care about having a phone app. I think that the best subs are the ones you don't notice -- until you turn them off. The RSL 10E fits all of my criteria and does so without breaking the bank. However, I will say this: I have a pair of THX certified subs in my theater that cost a lot more, but I think the 10E's run them very close competition. Dealing with RSL is a joy. Efficient, quick, "they say what they do and do what they say." If there were 10 stars in the ratings, they would get them all.
