Denon AVR-1909 removed 2 surround back speakers, must do setup again?

I removed the 2 surround back speakers, I decided to go from 7.1 to 5.1.

Because of practical living space situation.

My question, do I have to do audyssey setup again, because I removed the 2 surround back speakers?

Sorry for spelling mistakes, not often type English.

It's probably a good idea, even though there is only a very small number of Blu-rays and DVDs that actually have 7.1 sound.

I would definitely run the set up again, the sound stage will have changed and the missing gaps will need to be filled in.

Yes i'd definately run it again as like Michael has just said there,s gaps to fill in & the amp will need to know they've gone for a more accurate set up.

Thanks for the advice.

I will do the setup again.
