We also use the FM receiver much. It is supplied with a small wire antenna, these completely enough (we have because no satellite radio antenna connection in the apartment). I have the cable antenna just pushed under the baseboard.
Also streaming via Bluetooth works fine with an iPad 4 and in very good quality.
Not so great are the cable lengths, this will not be enough in many cases. On special player plug attached. Therefore, you have to extend the cable to the speaker end. The speakers have normal cable clamps, so just get and solder a few cables. There are very thin cables while (guess 0.5mm max conductor cross-section). The front cables are shorter than the rear. Everything is designed so that the player is under the TV.
The speakers all have rear recesses in it with which you can hang the speakers on the wall. Just a screw into the wall and the speaker push it. In the instructions which of feet (Tallboy HT-F5530 or HT-F5550) mentions the there is seemingly in a different version or as an accessory. We have all the speakers are on the ground at the moment and pushed the cable under the baseboard - sounds good anyway.
Our TV hanging on the wall and we had routed all the cables in the wall. Even the AmazonBasics HDMI cable we had relocated. Unfortunately not the simpler Samsung TV the Audio Return Channel, this was only after a call to the hotline Samsung clear. So you need an HDMI cable which the Audio Return Channel which can the Audio Return Channel support and also a television of that. In our Samsung TV UE50F5570 an additional optical TOSLINK cable was necessary to reflect also the TV sound over the sound system. We have used a simple 6EUR Mumbi cable, now it works.
The LAN (Internet) transmission over HDMI is not working (our TV has WiFi, but that may not provide the sound system via HDMI available). You need either a network cable to the sound system to the Internet router. There is also a USB port where you can connect a special WLAN stick (optional WIS 12ABGNX). According to the manual this only works WLAN Stick.
DivX playback you have to register apparently somewhere?!?
