What is the frequency response specifications for 7.1 surround sound channels Are all 7 about 20 to 20K Hz other than center which is usually voice dialog only?

Unlike the old Dolby Pro Logic Surround, Dolby Digital 5.1 and 7.1 have full frequency response abilities for all surround channels. In reality, most sound engineers limit the frequencies sent to the rear and surround speakers since the typical home setup has smaller speakers in these positions. Of course, the LFE channel is limited to 100 to 150Hz for true sub bass operation, but can be pressed into service to provide low frequencies to compensate for small left and right front speakers.

Do you need more than two speakers for surround sound?
For true surround, you need at least 4 speakers. There are systems that create a 'virtual surround sound' using acoustic tricks from a single array of speakers, but the effect is limited in frequency response and true surround realism.

Does surround sound use six channels?
it has 5 but the .1 channel doesnt count as a speaker because it is a subwoofer
Can you use only 5 speakers and 1 sub with 7.2 surround sound?
Yes. 7.2 is actually a misnomer, as there isn't 2 sub channels, just two outputs for dual subs. It should actually be called 7.1. There are very few 7.1 mixes around. Just about everything is 5.1 in home theater. You can configure any 7.2 surround receiver to combine the left and right surround channels with the left and right rear channels to allow you to use a 5.1 speaker system.

I have a stereo receiver with four channel speakers and a subwoofer is there a way I can have the two front channels as regular sound speakers and the two rear channels as surround affect speakers?
If the receiver is just stereo, not surround sound, you will not be able to create a surround sound (front, centre, sub, surround) setup.
What do people mean when they say surround sound 2.1 or surround 4.1 5.1?
Speaker systems are described using a 2-part notation in the form of X.Y, with the X referring to the number of full-range channels (regular speakers) and the Y referring to limited-range speakers like a subwoofer. For example, a 5.1 surround system has 5 full-range speakers (front, left, right, left surround, right surround) and a subwoofer. Likewise, 2.1 means that the system has 2 regular speakers (presumably a left and right channel) and 1 subwoofer, and 4.1 means 4 regular speakers (left, right, left surround, right surround) and 1 subwoofer. Another means of notation uses the format X/Y.Z, where X is the number of full-range channels in front of the listener, Y is the number of full-range channels beside or behind the listener, and Z is the number of limited-range channels. For example, a typical 5.1 surround system could be described as 3/2.1, because there are 3 channels in front of the listener (left, center, right), 2 behind (left surround, right surround), and 1 limited-range subwoofer. To expand it even farther, there is another notation, expanded to include matrix decoders, with the format X/Y:Z.A, where X is the number of front channels, Y is the number of rear channels, Z is the number of channels in the rear in total (including channels reproduced by the rear using sound effects), and Z is the number of limited-range speakers. So, the notation 3/2:3.1 (referring to Dolby Digital EX) means that there are 3 channels in front (left, front center, right), 2 speakers in back (left surround, right surround) which produce 3 channels (left surround, rear center, right surround), and 1 limited-range subwoofer. For more information on this type of notation, you can visit Wikipedia at http://en.wikipedia.org/wiki/Surround_sound#Notation

What is better Audio CD or DVD Audio?
I've been an audio engineer for the last 10 yrs. CD audio is 16 bit resolution at 44.1kHz sample rate. It is a stereo recording. This means it has a serarate left and right channel. DVD audio is 24 bit resolution at 96kHz samplerate (more than double that of CD). It is a 5.1 recording. This means that it has seprarate left and right channels, a center, left rear, and right rear channel (that's the 5 in 5.1). It also has a dedicated Low Frequency channel or "sub woofer channel" (that's the 1 in 5.1) So DVD has higher resolution and a higher sample rate with more channels that allow for surround sound where CD is not capable of doing true surround sound. Yes I know that you can play a CD in your can which has both front and rear left and right speakers, but that's not surround sound. It merely duplicates the front channels and plays them in the back. They are not dedicated surround channels like on a DVD or a 5.1 surround system.
