First off before buying a wireless speaker kit you need to check if your reciever has the option for preamp outputs. Usually only high end recievers do but if yours has preamp outputs dont get this kind of speaker kit get an rca wireless audio kit (pro audio makes one and it's on amazon). You can get one with the left and right channel inputs/outputs or a single one then use y splits if you need to. Preamp outputs are those red and white rca cables if you dont know what I'm talking about. Using preamps to do your wireless speakers not only is better audio quality wise but will also give you the option to get your own 2 channel amp with your desired wattage per speaker. My reciever unfortunately doesn't have preamp speaker outputs so I this is the kit I had to go with.This kit will be the third and most expensive wireless rear speaker kit I've bought. I've tried 2 other brands one of which was the rocketfish kit from bestbuy. It was worked okay but at only 25 watts per speaker it just didnt get loud enough and had some serious clipping/crackling problems when playing at high volume. If you have cheap speakers 25 watts might be enough but my speakers are rated 20-150 watts so 25 just is not enough. The dynasty kit being the most expensive is worth just for the fact that you get 50 watts per speaker and the option to hook up a subwoofer. So far I haven't had any issues with connectivity and my 2.4g/5g router sits a couple feet away from the transmitter. Most routers nowadays will automatically switch to the least crowded 5g band so if you have issues with connectivity you really should check your router settings and either change channel bands manually or check that auto channel is enabled which most are enabled by default. Another thing I noticed with this kit which other people mentioned is random popping noises. I had issues with popping or crackling noises on every single wireless speaker kit I bought inclusing this one and it mostly happens when playing at high volume or during intense scenes. I think the problem is with the input end. If you're reciever is sending too much power to the transmitter I think that's what causes the popping or crackling noises. What I did on all of my wireless kits to get rid of the popping noises is raise the volume all the way up on the output/amp end of your kit then use your receivers auto calibration to adjust and lower the volume to the rear speakers. This will hopefully lower the output from your reciever to the transmitter. Now this will vary depending on your reciever and how many watts it puts out per channel which is probably why only some people have issues with popping noises. If you try that and it doesnt get rid of the popping noises you will need to manually adjust your rear speaker volume from your reciever until the noises disappear. My reciever puts out 80 watts per channel and my calibration put my rear speakers at around -3db and I got no more popping noises. As far as sound quality goes this kit is excellent. Very clear and less static than my rocketfish kit. One thing I highly recommend for any home theater is getting noise filter clips that you snap onto your wires to reduce noise/static. I got a variety pack of them on amazon for 15 bucks and trust me it helps A LOT especially with these wireless kits. Almost completely removes static noises from your speakers. All you do is snap them onto your power cord lines on your reciever, subwoofer, speaker kits etc. If you have issues with humming from your speakers or you hear static in your speakers then is is an absolute must. Last thing i noticed with this kit is the delay which was double that of my rocketfish kit. This should not be a problem in most cases however in some cases for example when I stream a movie through my tv only the audio gets sent back through hdmi to my reciever which will take that audio and adjust for the year speaker delay which causes some very serious lip sync issues. This can be adjusted for manually in my tv and or reciever but it is annoying. If your video sources pass through your reciever then to your tv then you shouldn't have any problems with this.I spent a lot of time and money trying to find the kit and I tried to include as much helpful information here as I could. Hopefully this helps someone because i know there's a lot of people out there that are frustrated with the lack of options for wireless speaker kits like I was.Pros:1) Best option on the market currently for recievers without preamp outputs2) 50 watts per speaker3) Clear sound4) Easy setup5) Optional speaker/and or sub configurationCons:1) Expensive2) White color box doesnt blend well with most home theaters. There should be a choice for black.3) Issues with popping at high volumes. Adjustments needed to mitigate this problem.
