Soffit mountable speaker only costs 549 dollar. cheap right?

As far as i know in wall (soffit mountable) speakers are very expensive.. but Bluesky announced a pair of soffit mountable speakers, I/ON,which is very cheap. Making a DIY filter and building a sealled box are not necessary for this sort of speakers. therefore mounting the speaker and building a control room could be easier.. even more, Bluesky Media desk 2.1 is more famous for alternative Yamaha NS-10m studio than yamaha Hs series Is there anyone who bought cheap and good soffit mountable speaker? http://abluesky.com/asp/catalogue/produ ... code=00072
