Could be a number of reasons. Internet ads are controlled based on algorithms. I also think that younger buyers don't have large houses (or houses for that matter) so smaller speakers work better in apts, condos, or small houses. And, smaller speakers with a woofer are really sounding good. I listened to a pair of B&W bookshelves with a Rel sub and was impressed at the sound in relation to the system cost and space required.
