I am thinking of getting a Logitech Z515 * wireless speaker, but my question concerns any remote speaker. Before buying I would like to know, will selecting the remote speaker disable the built in Mac speakers? If so, is there a way to have both receiving audio? *Yes, I know. The reviews on the Z515 are not too good for audio quality, but after spending a boatload of money on my IMac, there's not much left for extra goodies. I can get the Z515 for $80.
