We have a large room, wide but not deep (15'). We are buying the Pioneer Elite SC-25 but speakers can't be too intrusive. It seems like we're down to the JBL CS6100 or the Klipsch Quintet SL (I have a good sub). We'll be using a custom-built computer to drive movies and audio. Can anyone give me input on these speaker choices or others in the unobtrusive but good sounding, under $1k arena? All input is appreciated.
