Sounds good so far
I wanted to scale down my bulky tower speaker entertainment system for a small living room. This works well. Mostly I try to keep the volume to a minimum, and that's not a problem, especially with the night setting on. I have been using Dialog Enhancer, but I wish there was more documentation about it. Apparently that setting and Night cannot both work at the same time. One major question I have is: when, if ever, is Dialog Enhancer reset to the default? And more importantly, WHAT IS the default setting? I assume it is Low, but I would appreciate an official answer to that. Since there is no display, I don't know where to find this information.

Capable monster ????????
So how do I start this ,? Hmnmnm I was trying to replace my Bose companionIII speakers long time ago , my purchase price in my country was 270euros so ,one star ? must go down . I kinda take it shortly, the sound is over average nice ,manageable by connected device in depth, it's just a pint pointing but any device connected hdmi optical jack BT ,you start rising the volume on soundbar it's quiet until 2.5 dots then it's loud enough, sorry me but 3D sound or dolby Atmos impression is kinda at placebo levels ,,, so it's only kodeks no sound effects????? Did anyone try this at laboratory???? it don't have any AVL (DRC) ,imagine LGsp2 (cost 79€)have an Android app for all the settings ,what I missing is dialog enhancer works in movie mode only ,it can be used in music mode too ,especially some 90'rap music ,mid gives more midrange with some highs to overall ,high give narrow mids with more highs and less punchy bass under 60-80hz so yes dialogue comes very clean and action sound stays nicely bassy ,.I like to volume up in heavy metal ,I wasn't able to distort speakers with loudness Denon have mind of headroom,. I wish Denon can manage an easy app and some adjustments in volume display in next USB update :) please ?!!! In 2023 who don't have AAC kodek in bluetooth audio ??? Cheap 6€ BT transmitter , . So I give 4 stars for sound quality ,5 for ease of use because just plug it in and go,set up too, and appearance and design I give 3 I meant visual it looks like any other Philips ,Sony , blablabla you name it ,it's visual side needs to sell that built-in subwoofer because in some site they don't write it in specs lot of peoples don't know it can sound good even better than mainstream JBL , I wasn't measuring this yet but I think volume output is somewhere around 40-50watts related to 3way regal speakers ,so it's full filling room audio on 25metres square, I really appreciate that I don't see any passive radiators or how they call it ... Comes with bunch of cables ,hdmi ,optic, 3.5mm jack ,and the led light is soft in night it's not intrusive ok enough:)))

Denon does it again. Quality at a fair price.
Fantastic device. Sleek styling, ease of setup and operation. Not many speakers of it's kind have a subwoofer out. The remote is also well designed.

I was very surprised when I tested the product out. I was choosing between this and the Bose speaker that was around the same price on Black Friday. I am sooo glad I went with this. My friend got the Bose and ended up returning it to get this. Love it.

Solid Entry Level Sound bar
Solidly built entry level sound bar for bedrooms and similar sized spaces. Includes subwoofer out connection not typical for sound bars in this price range. Built-in down firing base speakers, so placement on a table or shelf is preferred for max space.

Good sound quality but spatially not as exciting as a multi speaker 5.1 system, again not a surprise for entry level sound bars, so adjust your expectations. The reason for the 3-star is two fold - one a HDMI connection without eARC, requires the sound bar to be powered on. Additionally, there is no graphical display on the TV for sound changes.

Bought (2X of these DHT-S217 - (1) arrived defective and had to be sent back. I will BUY another NEW one to replace the defective one BUT the (1) that did/does work sounds AWESOME for my "little" space. BUT - - You should really buy a shelf for this thing. I felt like a was going to fall off the wall, even though I'm pretty good about that, NOPE! Only found a 36" X 4" picture frame shelf at MENARDS. I had to cut 3" holes in the bottom for BASS ACCESS. Most likely paint it soon. This is rough-cut pix - >> But now, it's not going anywhere and hung directly under TV. As you can see there is a 1/2 " lip on the front-side of the shelf. The bottom feet rubber pads, holds the unit in place and keeps it from falling off the front. I also placed (2) X square GORILLA PADS furniture pad protectors, about 2" square on the backside of the unit to buffer any vibrations - WORKED GREAT!! OVERALL RATING FOR THIS PRICE IS 5 STARS!!!

Everything I wanted.
Great soundbar for the price. I wanted one without a separate subwoofer because base freaks out my dog. I love the night mode and voice enhancement too. Perfect for any situation.
