Ok I own a 5.1 and I know there is 6.1 with a speaker in the back but I saw something on another site talking about 7.1. It never said where the other speaker went I`m thinking above you (that would be cool) anyway any help would be nice.

Two rear surrounds (in addition to the center, two mains, two surrounds, and sub). I believe this is the ES feature. Supposed to give greater realism when the helicopter flies right over you.

0.1 more than 7.0

I own the TXDS989 by Onkyo and what it does, is take the addtional channel in a 6.1 set up and split it into two rears instead of one speaker....Sounds pretty impressive.. The best demos i have used were in Art of War, Perfect Storm,and Gladiator.... it works in DTS-ES as well.... The Onkyo will also take a normal 5.1 soundtrack and utilize the back speakers by splitting the left and right rears into the back rear speakers... It sounds good on some movies, but not others.... I would recommend that receiver to anybody looking for the latest in technology in a reciever...if you have any other questions..feel free to email me at:

7.1, 8.1, 9.1....
7.2, 8.2, 9.2....

When will it ever end?
Just how many speakers can you fit in the average sized living room?

I'd be more than happy if they just left it at 5.1, anything more is just sheer overkill !

Actually, the 6.1 (and presumably 7.1) is a step backwards.

In 5.1, all the channels are discrete digital channels - no matrixing.

In 6.1, they dust off the Pro Logic circuitry and use matrixing to get an additional channel.

Thus, we are back to old Pro Logic technology - all so that we can get one more channel behind us. And, the ear is not particularly sensitive behind you anyway - if your two discrete left and right surrounds are at least a little behind you, that should be sufficient for a living room.

Take a look at the EX/ES explanation at http://www.geocities.com/Heartland/P...urroundex.html. I don't think this represents a step back at all.

Personally, I'm waiting for the next "standard" before I upgrade again, I can't affored to upgrade for eveyr small advancement.

It's fiction

Well if it's a warp factor, 7.1 would be about 360 times the speed of light. What's your hurry?

From the link above:

Limitations common to the Dolby Pro-Logic decoding scheme still exist in Surround EX. In particular, since DPL is based on detect of signal dominance in the soundtrack, subtle elements that may be intended for the surround back channel may be steered towards a much more dominant right or left surround. So you have a ‘center wandering’ effect. In soundtracks that are not EX encoded (you don’t have the Surround EX specified 45 degree phase shift in the l/r channels) rear effects can tend to collapse and ‘blob’ up in the surround back channel. The above limitations can be dependent upon the quality of the decoder being used.
This is all the stuff that we left behind by going to 5.1 in the first place.

In contrast, at least the DTS-ES has 6 discrete digital tracks (plus the LFE track). I don't mind them adding more rear tracks, as long as the disks continue to support the 5.1 system. I noted that DTS-ES disks do indeed decode an extra track if you have a new decoder, or else they give 5.1 . The question is whether the surround channels are missing the rear information if you use 5.1 or if they include the rear information both ways (which spreads the rear information across all 3 channels).
