    I'm designing some surrounds for my Dolby 5.1 setup, I was wondering which frequencies are sent to those speakers and the center channel. Or are they all full range?
     
  2. With post dolby prologic (ie DTS and DD), ALL speakers get sent the full bandpass (20hz-20hz) if you set you speakers to "large". If you set your speakers to "small" then the reciever will cross over the responces for you. Typically, small means that the speaker will get a 2nd order XO at 80hz. anything below the 80hz gets sent to the subwoofer. Hope this helps

    Anthony meant to say 20hz-20Khz. So they are full range.

    Yes 20hz-20khz.
    However, the higher the notes the more directional the sound. Since surround speakers are supposed to completely envelope you in a soundfield they can't have to much direction. Dan Richie of Gr Research suggests that his 5.25" woofers in a dipolar config withOUT a tweeter would form a great surround speaker. These woofers have an F3 of about 13000hz.
