Question:
Right, bagged a 36" widescreen and now thinking of upgrading my set-up a tad.
If I get a Yamaha 640SE which has 6.1 surround what do I use for the centre rear? Do I buy another centre speaker like the front or use a 'normal' rear surround speaker? mmmmmmmm?
The Yamaha looks tempting for £299 at QED!
Try and get it to match your existing rears.

Yeah, treat it as another rear not a center channel. I was unable to get a matching speaker for mine (I have british speakers and am in the US!) but I picked up a single Boston Acoustics speaker which does a superb job as my surround rear. Of course if you have the ability on the amp (I do but not the room/money at the moment to implement) then wire up for 7.1 with two rear surround speakers instead of the one.
It might be easier to buy another pair of your existing rears, and wire them to run as a single centre. This will allow you to overcome the reversal issues of sounds on the median plane.:dork:
Basically, humans can't really determine whether a sound coming from directly behind us (and between our ears) is infront or behind. Its mostly contextual, so if your brain expects a sound to originate at the front, that's where you'll hear it... Voices are a good test for this.
If you nudge the centre off centre, this fixes it. If you put in a mono pair, that fixes it too (if they're wider than your head)
Oh yeah, one last thing. The Yammy set up guides suggest that you should time the speakers so that they appear equidistant from you. That means the front centre should be positioned (or delayed) to put it just behind the fronts (trigonometry here!) and that each rear should be as far away as the fronts. If you don't have a huge amount of space behind your sofa (ideally, the sofa is in the middle of the room) the effects of the rear centre are pretty much compromised.

(I have the 630 btw... Lovely amp :))
Crikey! My rears currently fire overhead and are 3ft away from my viewing position. The new rear centre would be a foot behind me! So unless the amp has some jiggery pokery to fool my ears it aint gonna sound that good?
My current rears are old yamaha ones, I want to upgrade, so after what you have reccommended I may buy a new set of rears and use my current ones as the new rear centre wiring both in? Sounds interesting.
Currently have Mordaunt MS25i floor stander fronts, a Paradigm centre speaker (CC170). What rears? Maybe the bi-polars from RS at 50 squids?
The Yam 630 looks good and is £250, do you know why the 640 is £50 more and for what?
Cheers
Do many of the latest DVD releases have DD6.1 encoded?
Flanners,
Spec sheets, manuals, flyers, for the ax630se (http://www.yamaha-audio.co.uk/archive/homecinema/amplifier/dsp-ax630se/index.php) and ax640se (http://www.yamaha-audio.co.uk/homecinema/amplifier/dsp-ax640se/index.php).
-edit: about +10W to each channel, and maybe 'DTS NEO6' (both models use the same chip though...?)
cheers mate, most helpful, now where was my Visa card...........

Actually there isn't a DD61 it DD5.1EX as DD-EX is only matrixed rear surround channel. DTS-ES can be either matrixed in the same way as DD-EX or Discrete in that an extra channel is encoded onto thte DVD. Not all "6.1" amps car able to handle DTS-ES Discrete and some can only do matrix (I know some of the earlier Yamm's in the mid-range were like this).
Oh and to answer the question, quite a lot of DVD's are getting released ofr a DD-EX track or a DTS-ES track now :)

Just read this, it looks like only the 640SE can do DTS-ES Discrete according to the specs, the 630SE is DTS-ES 'Compatible' which could be DTS-ES Discrete but not approved or could be just DTS-ES Matrixed?
Personally I have the Pioneer 811s (http://www.homecinemaheaven.com/cgi-bin/Search.cgi?prod_info/amps/vsxd811.htm&Pioneer&811) which I find a superb amp and replaced my old Yamaha 596a which I had had for a long time before moving to the US.
Agreed. manual for the 630SE says of the processor indicator "MATRIX lights up when the Dolby Digital EX decoder or the DTS-ES compatible decoder is activated" (pg8).
The bumf on the 640SE says 'Compatible with the newest 6.1-channel movie sound formats including Dolby Digital EX, DTS-ES Matrix 6.1, DTS-ES Discrete 6.1'
Gone for the 640SE, what the hell it's only money I don't have! Cannae wait tho!
