Jayson H Posted June 20, 2020 Share Posted June 20, 2020 I have recently upgraded to a Yamaha Atmos A/V receiver, and still running a 5.1 speaker system. At the front I have Wharfedale Diamond 8.4 fronts, Diamond 8 centre, 150W sub, and Tannoy Mercury M2's as rear surround. I have a pair of Aaron SS 30's left over from an older set-up, is there any advantage in hooking these into the system? Most of my content is DD 5.1, will mismatched speakers add or detract from the surround sound effect? Or will they be dormant until using ATMOs content? These are the specifications from the manufacturer 4" SURROUND SOUND Frequency response: 95Hz - 16kHz (+/-3db) Power Rating: 50 watts Sensitivity: 89db Impedance: 8 ohms Base alignment: Infinite Baffle Size: 255H 155W 190D 3 kg ea Cheers Link to comment Share on other sites More sharing options...

As long as they are positioned well wrt to the dolby guidelines. 53 minutes ago, Jayson H said: will they be dormant until using ATMOs content? That depends on how you configure your receiver. ie. to up mix 5.1 content, or not. 53 minutes ago, Jayson H said: mismatched Run your receiver speaker calibration (YPAO or whatver Yamaha call it) and you will be fine.

betty boop Posted June 20, 2020 Share Posted June 20, 2020 I have used different centre to mains, same side surround as a centre and then different rear surrounds. it can work. in end i did end up upgrading and it is a much more seamless experience ....matching does help. but doesnt mean you can't use mis matched as not like completely way off in sound ! all your speakers will most definitely be utilised in a atmos setup as dolby surround upmixes to utilise. even if native material is 5.1 its actually pretty amazing what it can achieve Link to comment Share on other sites More sharing options...
Snoopy8 Posted June 20, 2020 Share Posted June 20, 2020 Having matched speakers make a difference for multi channel music. I had superb SGR active fronts and Monitor Audio Apex A10 rears. I now run all Monitor Audio Apex speakers and discovered that it actually improved multi channel music, a little bit more coherent. I now understand why someone used 4 B&W 802s for their setup, plus B&W centre! Yes, 802s for the rears! No difference with movies... Link to comment Share on other sites More sharing options...
SGS Posted June 20, 2020 Share Posted June 20, 2020 Don't sweat it. Whilst mismatched isn't ideal in a perfect world, its not that big a deal. For ages I ran Energy mains and ALR Jordan centre and rears. I now run Energy fronts and centre and ALR Jordan rears. I never once thought these speakers were mismatched causing horrible output. Changing the centre improved a bit but I never minded how it was, decision to change was more about power handling. If it sounds good, it is good.

Jayson H Posted June 20, 2020 Author Share Posted June 20, 2020 Cheers guys! If I set them up like the attached, would I be best off putting the smaller speakers as back or sides? or no difference? Link to comment Share on other sites More sharing options...
WasM Posted June 21, 2020 Share Posted June 21, 2020 Try both and see which you prefer - you'll need some demo material. You'll have to run the auto calibration after switching the speakers around. If the Yammy AVR can output 'multi-channel stereo' - play some music to test. Link to comment Share on other sites More sharing options...
