My use of the Bose Companion speakers is for quiet dinner parties, where the music is all instrumental. Their sound augments the onboard speakers of the S950 and provides a fuller sound overall. However, another option I use (with vocals, too) is a pair of 150 watt Behringer B205D monitor speakers. They will get loud, but, for sure, weak in the bass response. But, they are very light weight and easy to carry. Mackie makes a monitor that looks just like it. Size and weight are big deals for me. That's the first thing I consider before buying any new gear.
