One can't help but factor in the looks as we see with our eyes first. As Hannibal said, we covet what we see every day. How much weight that carries depends for me as something that lacks aesthetics, having awkward proportions, or is downright ugly gets a pass, for me.
Components didn't used to have to match but the last two incarnations of my system does and I've grown accustomed to it. With speakers, I give a lot more latitude as long as they sound great. Great sound overcomes looks in that regard.
All the best,
