Q. Can I use different models for my home cinema surround loudspeakers?
Answer:
In a home cinema system, the bottom
octave of the surround loudspeakers is not used as these frequencies are directed
to the subwoofer so, although in an ideal world all 5 or 7 loudspeakers should
identical or very similar, there is a bit of latitude when practical space
constraints need to be taken into account.
