Yamaha Audio Store Wx-021 40 Watt 5.1 Channel Wireless Bluetooth Speaker with Alexa (Black)

I bought the soundbar yas 408, a month back and was very impressed with the sound quality. However I was missing the wow factor. Now added the two music cast speakers and I am pleasantly surprised with the amazing surround sound experience. The only downside is that these are very expensive. I suggest all owners of the music cast sound bars to invest in the surround speakers to enjoy the high quality immersive experience

I am writing this review around a Yamaha musiccast WX051 pair + YAS408 - trying to setup the WX051 pair as surrounds for the YAS408. Even though this product is a WX021 the concepts I write about should help here. I benefitted by reading some of the customer experiences on this product.My first post here. I read this full thread because I started having trouble with adding a pair of WX051 as surrounds to a YAS408 Bar. They kept failing with errors 6000B0000, 600b30000, 600330000. Some history here. I had a single WX051 which used to pair as surround with the YAS408 easily. I never had any trouble unpairing and pairing it as surround. Then I got a second WX051 to make a real surround with the YAS408. I noticed the surround setup kept failing. Actually I had not use the first WX051 as a surround with the YAS408 for a few months. I tried the singleton WX051 as a surround with the YAS408. It failed. That was puzzling. I knew that worked well flawlessly. Then I came to this forum and read all the posts. Instead of static IPs I made sure my DHCP server will assign reserved IPs for my two WX051 and one YAS408. This is as good as static IPs. This also did not work. Then it struck me I had done one change in my home network.In my home I have two WiFi access points. Initially I used to have separate SSIDs on both Wifi access points. In fact I also had separate access points for 2.4G and 5G. Earlier I had configured my single WX051 and YAS508 on the SSID given to the 2.4G. I had trouble with my laptops and phones as I moved around the house and often they would not shift to the stronger SSID. After reading some stuff on Wifi, I decided to make both my access points use the same SSID (including 2.4G and 5G). This definitely helped my roaming inside the house. (NOTE both Wifi access points are just ethernet-wifi radios. The DHCP server was common from a router to which both access point connected).When I started testing with the second WX051 I did not realise my Wifi topology had changed. I realised that it is quite likely my YAS408 was probably connecting to access point 2 (it is in a location where both access points have nearly similar signal strength) but the WX051 was connecting to access point 1. (both using same SSID also same SSID for 2.4/5G and both access points in the same IP subnet). I read here and in one Amazon customer feedback that the Yamaha devices establish their own ad-hoc network. I argued that if the Yamaha devices are not connected to the same access point they refuse to form the adhoc network - because Yamaha in their design must have assumed that such Wifi arrangement will only happen when there are large distances - and in such cases there was no way surround can be created.So I switched off all Yamaha devices. Switched off my distant Wifi Access point and powered on my Yamaha devices (two WX051 and one YAS408). Went back to the musiccast app on the phone and trie setting up surround on both WX051. IT worked in first attempt without any issue. Once the surround was setup, I went back and turned on the second access point. No problem with surround working.Conclusion : I think for the Yamaha to form its adhoc network for surround, it expects all its devices are talking to the same Wifi Access point Radio.
