wally flick Posted June 17, 2005 Share Posted June 17, 2005 So we just pulled the wire for the speakers in our soon to be finished basement. Anyway, my wife was standing there looking at the extra cable we pulled on the chance we might upgrade to 7.1 in the future and she said, Why dont we just buy two more speakers? Helluva woman huh? Ive got a 7.1 receiver just waiting to jump out of the box when the construction is done. Looks like many of your posts to the Lets see YOUR Home Theater thread have 7.1 set ups. Are there enough DVDs available for me to drop the extra $? Will I hear a difference 7.1 vs 5.1? Quote Link to comment Share on other sites More sharing options...
jacksonbart Posted June 17, 2005 Share Posted June 17, 2005 Yes I would recommend it. There are not many films with discrete 7.1 out there but they are increasing and most receivers can matrix the surround sound to extend the 5.1 to 7.1 anyway. The quality with which each receiver does this I am sure varies, but in my case it works great. Quote Link to comment Share on other sites More sharing options...
DrWho Posted June 17, 2005 Share Posted June 17, 2005 There isn't any discrete 7.1 material out there...the most right now is 6.1, which the Dolby EX and DTS EX formats support. As far as matrixing goes, every reciever uses the same algorythm (as long as they use DPL II or DTS Neo). I wouldn't be surprised to see the new blue laser format support 7.1 in discrete channels...heck, maybe even 11.1 (which movie theatres use). Some yamaha recievers include options for front effects speakers which are basically two extra mains that you mount up high near the cieling, which project a much larger sound field. Anyways, the future of medium formats are such that more and more channels will probably be added. Anyways, I personally would prefer 5.1 with higher quality well positioned speakers than 7.1 with lesser quality. Quote Link to comment Share on other sites More sharing options...
wally flick Posted June 17, 2005 Author Share Posted June 17, 2005 I noticed the Denon 5805 is a 10 channel receiver or is that just two full 5.1 zones? I already have the 5.1 system purchased so converting the extra $ to a better 5.1 rig is not an option. I was just wondering if it was worth it since Ive got all my walls open now. I also have a hunch that 6.1 and 7.1 might pop with BluRay or other Hi-Def DVD formats. I guess you should try and future proof whenever possible.

Pako Posted June 17, 2005 Share Posted June 17, 2005 It's not about quality, it's about quantity. Just kidding, but seriously, I couldn't justify NOT going 7.1. Even with 5.1 programmed material, the 7.1 benefits can be heard in my experience. I will say, however, that DD EX and DTS ES material sounds pretty darn nifty compared to non EX/ES material. ~Cheers~ Quote Link to comment Share on other sites More sharing options...
BobbyT Posted June 17, 2005 Share Posted June 17, 2005 You can layer DPL2x over DD an DTS for great 7.1 sound also. Quote Link to comment Share on other sites More sharing options...

As far as matrixing goes, every reciever uses the same algorythm (as long as they use DPL II or DTS Neo)." DD EX isn't 6.1 discrete either. They just matrix encode the third channel into the surround L/R channels same as DTS ES. DTS ES Discrete 6.1 does have a discrete sixth main channel of info but for backwards compatibility that channels info is also matrixed into the surround left/right for playback on regular DTS or DTS ES decoders without looking the info in that channel. For expansion from 5.1 to 7.1 the options available are PLIIX on top of 5.1 DD or DTS or Logic 7 (Lexicon or H/Ks) on top of DD/DTS.

Frzninvt Posted June 17, 2005 Share Posted June 17, 2005 My NAD T163 can take any 5.1 signal and matrix it up to 7.1 so for me it is worth the extra speakers. It also has dual subwoofer outputs so I run a 7.2 configuration. The Star Wars films are DD EX and the use of the vertical Cornwalls in the rear along with the Klipschorn's makes a substantial difference I can assure you. I have the ability to jump it back and forth from 5.1 to 7.1 and depending on the DVD soundtrack it makes a noticeable difference jumping to 7.1. Just my take on it.

boomer9911 Posted June 18, 2005 Share Posted June 18, 2005 WHY....WHAT FORMAT IS "OFFICIALLY" RELEASED IN 7.1....CURIOUS.... Quote Link to comment Share on other sites More sharing options...
marksdad Posted June 19, 2005 Share Posted June 19, 2005 7.1? it does not exist yet. when you run 7 speaks the rear 2 are matrixed, keep the speaks but you will find that the same sound is coming out of both speakers for now, it will be a while before there is true 7.1 Quote Link to comment Share on other sites More sharing options...
sfogg Posted June 19, 2005 Share Posted June 19, 2005 " keep the speaks but you will find that the same sound is coming out of both speakers for now" That isn't always true. With Logic 7 you can have sounds that pan from side right to rear right to rear left to side left. Shawn Quote Link to comment Share on other sites More sharing options...

We hit the limits of SPDIF with 6.1. Also, if your 7.1 is making the rear two channels identical, its time to get a Lexicon. I can testify to what Shawn points out, as my rears pan for sure.

sfogg Posted June 19, 2005 Share Posted June 19, 2005 "I believe the main issue is data transfer. We hit the limits of SPDIF with 6.1." Not really. 5.1 DD uses less then half the bandwidth of regular stereo 44.1kHz PCM audio. There are SPDIF transmitters that can do 192kHz stereo over SPDIF now. IOW, there is plenty of additional bandwidth on SPDIF for more channels if it is compressed. Shawn Quote Link to comment Share on other sites More sharing options...
