mdm1979 Posted December 29, 2012 Posted December 29, 2012 My room size is as follows The dimensions of the room are as if you are facing the screen height - 2.5m length - 5.8m width - 4.3 (screen wall) I have a 5.1 system at the moment but have upgraded to a better 5.1 speaker setup. I'm going to eventually sell my fronts & centre. I'm keeping my rears. They sit flush on my rear wall. I will turn these into Surround Back Left & Right Speakers (SBL & SBR) & add my new rears as Surround Left & Right Speakers (SL & SR). What's the minimum distance you would suggest between the (SBL & SBR) & (SL & SR) I know there's a lot of debate on the validity of 7.1 but I'm curious to try this setup with the handful of 6.1, 7.1 titles than sell my rears for next to nothing.
ArthurDent Posted December 29, 2012 Posted December 29, 2012 What's the minimum distance you would suggest between the (SBL & SBR) & (SL & SR) Most setup guides work in angles, so 90-110 degrees for the side surrounds and 135-150 degrees for the rears. You don't need 6.1 or 7.1 material to make use of a 7.1 speaker system because if your AVR is 7.1 it will no doubt have a setting that will generate signals for all speakers no matter what format the content is in.
betty boop Posted December 29, 2012 Posted December 29, 2012 (edited) the pic you have there is suggested thx setup of rears, given mosto f our program material is either dts-hdma or dolby truehd, I would go with the suggested 60deg included angle to main listening position. http://www.thx.com/consumer/home-entertainment/home-theater/surround-sound-speaker-set-up/ if planning to use thx post processing most processors will allow you to input the distance between your rears and adjust suitably. my rears are 1.6m apart, and work pretty well with my listening position 1.8m from the back wall definitely go 7.1 there is a host of material already with lovely 7.1 mixes, last three new releases I watched had 7.1 mixes which add beautifully to surround steering and soundfield created in the room. go for it Edited December 29, 2012 by :) al

Adds well for the enjoyment factor
kwtruk Posted December 29, 2012 Posted December 29, 2012 Love the opening scene to Transformers: Dark of the Moon where the Paramount stars swirl around you in 7.1. Are you using direct radiating or bi-pole/di-pole surrounds? I used 4 identical direct radiating for my surrounds, chosen over di-poles for music concert blurays and multi-channel (simulated) music, and also pc gaming, where the directionality of them is very useful and fun. In my experimentation i found having the side surrounds very slightly behind you and angled in front of the listening position, and the rears angled a bit to each side of the main listening position. Again, this is more applicable to my listening and also direct radiating type surrounds.
mdm1979 Posted December 29, 2012 Author Posted December 29, 2012 At the moment I'm looking at placing my surrounds at least 1m from the rear wall. I tend to listen to content as it is presented. 5.1 surround I'll listen in 5.1, cd = 2 channel & so on. Can anybody enlighten me on 11.2!? Why listen to contenr in 11.2 if it is presented in 5.1? I've read a bit about height speakers but if this isnt encoded on the dvd what use is 9.1 or 11.2 other than a bit of a ****?

This will be my new setup www.vaf.com.au DC-X35 front DC-XCC G4MKII centre DC-3 G4 MKII surrounds "correction" The Transformers 3 opening is great in 5.1. let alone 7.1. Shame about the rest of the movie though! haha Edited December 29, 2012 by mdm1979
betty boop Posted December 29, 2012 Posted December 29, 2012 (edited) floor mounted speakers in that case ? that probably lends itself little more to multichannel audio and an ITU-R layout. just have to be carefull the rears are not too over powering as more inline with firing at your ears. I've generally found surrounds about 2 foot above ear height to give that surround ambience with enough directivity to not distract by all means run 2ch as 2ch I do the same for music. but with tv broadcast where there is program that originally had a surround track and they are broadcasting as 2.0 there definitely is a benefit have found running as a 7.1 mix with post processing. but thats for you to decide. 11.2 is post processing with schemes such as audyssey dsx or PLIIz etc where additional channels eg heights above mains and wides either side of mains are created for more height and width to the sound field. personally have not found that much gain myself given the cost and also since this is a creation rather than in the source material but few have gone to the effort and like the benefit. see link below, shows additional speakers in itu-R layout http://www.practical...-placement.html taking a 7.1 or 11.1 system to 7.1/11.2 is matter of adding an additional sub though id suggest getting an avr or processor that can actually manage 2 subs rather than just one for best base management.

Newman Posted December 29, 2012 Posted December 29, 2012 Try putting them in 7ths of a circle. I put mine in 5ths of a circle and I summoned a warlock.

Big W has an awesome sale at the moment.
