For aesthetics in the house you want two things. No ugly wires that snake everywhere, and something that won't just be ugly, stocky and black.
I can't advise you on quality, I know absolutely nothing about quality audio speakers, but looks wise think of something with some color (preferable if it can be adjusted) and neutral shape that you can fit into your current interior design without it looking like a set of gargoyles perching on your furniture.
I also second in-wall speakers as you can go for a big ass model without it poking you in the eye, and cover it with a non-see through mesh in color with your wall or accessories.
