Axiom Home Page Forums General Discussion Home Theater Should I move from 5.1 to 6.1 or 7.1?

Hello Everybody!

I currently have 2 qs8s, 2 m60s, 1 vp150 and 1 ep shake the hell out of my house 500.

I have about a 2 foot area behind my couch from the back wall. Would I hear a substantial difference if I went to a 6.1 or 7.1? My room size is 15 x 18 x 9.

If so, what speaker(s) would you recommend for the rear?

Thanks for your opinions that drive me to spend more money.

Mike

Hiya Mike,

I suspect that opinions are going to vary.

Spiffnme (Craig) has on several occasions submitted that he did not find substantial value in making that change. I trust his judgement.

My own experience (in room somewhat larger than yours) validates Craig's. Before doing the permanent wiring (which would have been a huge pain) and buying additional Axiom(s), I ran a temporary, inelegant cable to a mis-matched sixth speaker for a while. I simply did not think that the extra, rear channel added much, if anything, to my enjoyment of movies.

Since I have ~10 feet behind my couch, I expected a much greater difference in my case than I would in yours. In the room you describe, I would be very surprised if you got a lot of bang for your buck by adding more speakers.

I do not believe there are ANY discrete 6.1 or 7.1 sources at this time. DTS and DD are 5.1 and the 6th channel is synthesized by your processor. It is also typical (if not absolute) for processors to send the same signal to both the 6th and 7th channels; using more than one speaker back there gives you broader coverage and higher SPL possibilities, but not necessarily different content.

Now, please understand, I like my music in good old Stereo, and respect the opinions of others that have had different experiences.

As to which type of speaker to use, some people have reported tremendous success by using their fancy processors to send DVDA/SACD signals to direct-radiating rear speakers (like a M2 or M22). I like my QS8's so much that I think the only reason to use a monopole speaker in either the surround or rear positions is if you are committed to multi-channel audio. So, some of the answer to your question depends upon your processor, amps and listening habits.

Based on what you've described, If you decided to implement this upgrade, I'd suggest a single QS8 and 6.1.

Personally, I'm saving those WAF points for a HDTV.

I'd love to hear your system some time!

First of all, correct me if I'm wrong but the new Star Wars DVD (Ep456) set is in 6.1 (DD EX). And I believe the DVD for The Alamo was in 7.1.

Now I have hung an extra pair of speakers on my rear wall which is ~12 feet behind the sitting area and a total of ~25 feet away from fronts.

I don't find it to be something I'd call amazing, but sometimes it does add a touch of ambience since I have that wide open space behind the sitting aread.

Judging by my experiences in the past where I had no room behind the sitting area I'd have to agree that it prolly doesn't add much, esp since there isn't a lot of material specifically programed for it. For me its worth it, but like I said, its just a couple extra speakers I had that I figured I'd put to good use. I do like having them there but I could live without it as well.

I have a 7.1 setup and like it. I figure my receiver has the channels, dolby IIx and I had the speakers so why not. I also like the sound, rented the special edition of top gun with DTS 6.1, not a great movie but the surround effects and the visuals of the jets are still amazing.

Personally I would go with 7.1 and have been with 7.1 for over 2 years now. I am a loyal HK receiver owner and thus love their logic 7 technology for music etc...where as DD EX makes some difference...not a lot but once in a while it will surprise you. For example....rivers...you can hear the water out of the 2 extra speakers for a while...where as with a 5.1 you will probably not get that extra "ambience".

MY 2 Cents.

Just curious: has anybody with a 7.1 system experienced both bi-polar speakers (like QS8) and direct radiating like M22s all four in surround and rear surround? I am wondering in an imaginary setup one could use the M22s in a 5.1 music setup and all 7.1 in a movie. I know this may sound weird but, when I think of my future HT, I like to imagine all these...

Some good comments here, all valid viewpoints as this is a very subjective question. I agree that you should try running some temporary wire and test the extra channel(s) if you can before making the permanent investment. Best way to know for yourself.

It's true that Dobly EX is a matrixed 6th channel but DTS ES can provide a discrete 6th channel. Available in a few titles (Lord of the Rings 1/2 Extended Editions, Chicken Run, etc). Hopefully more and more to come.

I apologize for my error regarding the existence of discrete 6.1 material, and appreciate the kind way our colleagues corrected it. I learn something new every day!

I have 7.1 and prewired my basement to accomodate for 7.1

When they start doing 7.1 discrete channels are we going to have to upgrade our pre amp/AV receivers or will they be able to handle this as long as it is DTS or DD????

HMMM interesting
