Upgrading to 5.1.2 sound system

Years ago i had a Canton CD10 sound system but then kids came and so it went into the loft (and stayed there) after a house move.

But now the kids are older I figured lets wheel it out and try and get surround sound back on, then after a bit of research I figured lets just and get something Dolby Atmos related!

My speakers are Canton CD10 and I intended to get Denon-avrx550bt. I have an old Yamaha Amp but my TV is 4k HDR OLED so I believe a new Amp is the way to go.

Would the new Amp be compatible with my Canton CD10 speakers though? I'm presuming they would be because a speaker is a speaker right? Or does it have a particular classification to output to newer formats?

I'm hearing that there's a difference between normal speakers and Dolby Atmos speakers. What's the difference? The Ceiling speakers I saw were Cambridge Audio C155.

I saw this link on the Dolby Website - https://www.dolby.com/us/en/speaker-...des/index.html and it suggests that for a 5.1.2 sound system, you need special speakers that fire the sound up?

If anyone has any specialism in this field it would be very much appreciated.

Your speakers should be OK, it's still the exact same system to wire them up to amps to this day. Dolby Atmos speakers are basically just "height" speakers which come in two forms: One is ground level speakers that have woofers/tweeters on top as well as on the front so they can bounce sound off the ceiling to create that height component (like in your link), and the other form is just straightforward ceiling mounted speakers. Obviously the first type are a little different to typical speakers because you'll have to wire for the both the top part and the front part, and the ceiling types are just a completely different type of speaker to begin with, but typical wiring because they only have the one function: Provide height sound.

The amp you were looking at isn't Atmos capable. You need one with 7 channels instead of 5 so it will do 5.1.2.

The .2 of the 5.2 it's referring to will mean it can power two subwoofers.

As to speakers, if you're happy with the Cantons then no need to replace. Just buy another two speakers for Atmos duty.
However, with those being almost satellite type speakers I don't think you'll get anything decent that fits on top of them to use as "bounce" type speakers, they're too small, leaving your options to either in-ceiling or mounted on the ceiling if you're keeping the Cantons. Quite a lot of members on AVF use Cambridge Audio Minx 12's as Atmos speakers as they're compact, have a good mount available, sound decent, and are available in white to match most ceilings. If on a budget you could look for a used pair of 10's
The other option again is to buy new speakers of the type that Shingster mentioned above such as the Focal Sib Evo's.

I have an Atmos system and am very impressed with it, however, don't expect your ceiling to come alive with sound, it's more subtle than that, but when you switch it off you do notice the sound "bubble" effect has gone. Also, you'll get more use out it than you think as the AVR will upscale regular 5.1 audio using Dolby Surround or DTS:X and introduce new height effects, sometimes with surprisingly good results (It must be witchcraft I tell 'ee)

Cheers guys, it's been doing my head in trying to re-understand it all and making sure what I have is fine.

I currently have a Yamaha YAS107 Soundbar but get episodes where the sound is out of sync but one's always been persistent is low dialogue compared to the gigantic explosion effects, so I figured going back to 5.1 will give more immersion.

Thank you too for recommendation on the Cambridge Audio Speakers. Given they're suitable for Dolby Atmos does that mean they are 'bounce' speakers?

Interesting to read your comments about 5.1.2 and the .2 referring to the sub woofer. But this link does say otherwise https://www.dolby.com/us/en/guide/sp...tup-guide.html
Thought I'd mention it incase I'm missing something. Or was you referring to the fact that full immersive Dolby Atmos needs 7 speakers 7.1.2?

No, the CA Minx is suitable for attaching to the ceiling to pointing down towards you the same way an in-ceiling speaker would. You could try to wall mount it above your Cantons I suppose and try to get the angle right for bouncing it off the ceiling but the best position for 2 Atmos speakers is above you, slightly forward. Having speakers bounce off the ceiling is a compromise and depending upon a number of factors one that may not be open to you

As to Atmos and the 5.1.2 you're misunderstanding me. What I'm referring to regarding the AVR is the one you pointed to, the Denon AVRX550BT is a 5 channel amp. It's down as being 5.2, the.2 is two subwoofers, not Atmos speakers. To do Atmos an AVR must have 7 channels minimum and be capable of processing Atmos audio.

The minimum for Atmos is 5.1.2. Your regular 5 (surround).1 (sub) plus 2 Atmos. That AVR doesn't have that. It's being marketed as 5.2 only as it has dual sub outputs I presume but doesn't do Atmos and only has 5 channels.

Full immersive Atmos would be 5.1.4 or 7.1.4 or 9.1.6 or............
