Re: SVS Prime Elevation
Funny you should ask this now, as there was just a small flame war over on AVS on this topic.
Purists argue that since Dolby designed the system for timbre-matched speakers, it is critical to timbre-match.
Others argue that as long as the heights are reasonably similar in FR, it's not that big a deal.
So YMMV.
