I have been an audio video enthusiast for many years and have owned and still own kit of very high value. However, for convenience I bought a Qr90 for one of my TVs and I have to say that I have been very impressed with the sound and value for money and have no complaints about the rear speakers at all. Yes, their volume varies, but that's what they are supposed to do. Those people expecting the rear speaker to function like the front or as a multi functional stereo pair have bought the wrong system. The volume of the rear speakers will vary massively depending on the how the source audio was encoded. Basic stereo only uses 2 speakers, 5.1 uses 5, 7.1 uses 7 and so on. The speakers that fire upwards are designed for atmos decoding, so they may not be active at all except when atoms source is played. Getting the best from your system can be complex as you need to ensure all your other components are capable of delivering the audio correctly. That means your TV, Blu-ray and even your HDMI cables all need to be capable of being transmitting the correct signals. Without the right signal some speakers will behave differently and the rears will be most affected by bad setups. My sound bar sits along side a pair of Devialet Phantom golds which are £5k for 2, and while as a stereo pair they blow the sound bar away, I think for the money the qr90 is a smashing piece of kit. So in summary, to those that are not happy, check your settings and ensure your other components can deliver bitstream audio and you will experience the best quality. If you want stereo, then go and buy a stereo system. Hifi is like cars, you can't buy a sports car and then expect it to be great off road. You just need to decide what you want and then get the right system for the purpose.
