It's also that a lot of speakers on the market (i'm not talkin about the big budget speakers, more the mainstream stuff) are very ugly plastic or glossy painted mdf boxes. While the trend in interior design is more natural materials (natural stone, light coloured wood, (loam) plaster, ...) and a lighter and softer color schemes with "earthy colours". Not many speakers in the mainstream market follow that trend. They are mostly in glossy white or black, with a very plastic feel. And people don't like that anymore. Looks is everything now, and sound quality is secondary for most people. Real wood (not mdf or plywood) is getting back popular for speakers pure for asthetic reasons, but it need to be light coloured wood, not dark brown coloured.
