The Denon sound bar is good, but not great, as advertised. The sound is good overall but does not fill the room. For a full room sound a subwoofer is a must. We purchased the soundbar for the DTS:X function, since we sometimes watch Blu-ray DVDs, but the lack of upward firing speakers,(as we had in our previous Yamaha soundbar) really impacts the feeling of fullness, and our room size is well within the soundbars advertised range. For music the soundbar does a good job.

I have enjoyed my Denon 550 Sound Bar for a few weeks. I specially like the base response with just the sound bar. I listened to Emmet Cohen trio with Ron Carter today and Carter’s bass came through strong. I will be adding 2 Denon Home 250 speakers for surround. I do not feel I will need to add a subwoofer.

I have Marantz/Heos system in my house and several Denon wireless speakers. The sound bar has less bass than the Denon Home 150 wireless speaker… but for its size works well and plays at a decent volume in a meduim sized bedroom……that said it is no power house and i will be adding the matching Denon Home series sub. Which should help alot. For general tv listening its perfect….music or movies the sub is a must have…period. Overall good balanced sound just needs bass. HEOS wireless works perfectly and streams high res music as long as you have a good strong wireless router signal.

Paired with a Dolby Vision capable Toshiba, sounds great on it's own. I plan to expand with some other Denon speakers in the future. Setup was fairly easy, a little toggling back and forth with the app to get it right. A bit disappointed that they haven't finalized Alexa integration yet (you can do some workarounds, but it is not a direct alexa device yet).

The Denon Sound Bar 550 is a game-changer! Its immersive sound quality brings movies and music to life, filling the room with rich audio. Sleek design, user-friendly controls, and seamless connectivity make it a must-have addition to any entertainment setup. An outstanding sound experience in a compact package!
