Hi I hope you can help me I've purchased a yamaha rxv6a recever. I currently have warfdale dx1 speakers which are 4 ohm however the amp is a 6 ohm system. Firstly will this cause any damage to either the amp or speakers. Secondly I was considering upgrading to onkyo sks ht588. But have been advised to keep my warfdales and just purchase two dx2 separates to achieve full dolby atmos iam at a bit of a loss as what to do

Risky with speakers having less impedance (resistance to current) than the amp. They could draw more current than the amp can provide. Clipping, distorting and perhaps damaging the amp. Usually it's the otherway round that is OK. So say an 8 ohm speaker with a 4 ohm amp. However with that said, the Yamaha manual does state:
Use following speakers.
6 Ω MIN
Use following speakers.
- the front speakers: with an impedance of at least 4-ohm
- other speakers: with an impedance of at least 6-ohm
6 Ω MIN
- For 6-ohm or higher speakers. You can also connect 4-ohm speakers for the front speakers.

So reading that I'd say if you are running just front speakers (the DX-1's?) then you are fine. Maybes just ensure there is adequate ventilation around the amp and change the impedance setting (as by default the amp will run at 8 ohm). However if you want to add more speakers (the DX-2's?) then the manual is saying "no" to those. They have to be at least 6 ohm. I'd personally say yes, you need different speakers but see if others chip in with more knowledge than me.

A quality amp will drive 4ohm speakers no problem.
However for budget avrs may have a issue. Having a subwoofer will help as typically speakers are lower impedance at lower frequencies so crossoving them high helps the avr out
Amolfiiers don't have a impedence that's the speakers.
A quality amp will double power every halving of the speakers impedence.
