By "fast" we're talking transient response to a signal. Planars are "fast" because they are accelerating a thin ribbon of mylar and the magnet for this ribbon is evenly dispersed along the length of the ribbon. The ribbon is only moving very slightly. So, it can respond very quickly to a signal.
Cone speakers are so much larger in comparison and respond from the center to the outside of cone. We're only talking about small fractions of milliseconds here. But since the Quads are such a different technology than a cone speaker it is better to pair them with a sub that won't smear the sound by being ever so slightly "behind" the rest of the frequencies being radiated. -- creativepart ------------------------------------- Great Guitar Websites: www.telecaster.com | www.strat-talk.com | www.gibson-talk.com ------------------------------------------------------------------------ creativepart's Profile: http://forums.slimdevices.com/member.php?userid=10822 View this thread: http://forums.slimdevices.com/showthread.php?t=33981 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
