Samsung HW-Q990C vs Samsung HW-Q990D

Hi SeriesXPro, We did not have the same experience with our unit. I suggest you try a factory reset or contact the manufacturer. As far as which sound preset to use it comes down to user preference. I would use what sounds best to you on various content. I hope this helps.

There’s no way, in your frequency response graph there are 2 obvious and insanely large craters at around 40, 100 and around 300 which is super obvious to the human ear, yall didn’t review this properly cuz if yall did, the evidence is already under your nose

Did yall connect the soundbar to the smart things app? If so, what settings/mode did yall use or turn on/off? My Q990D, no matter what settings I turn on or off, is severely lacking high bass compared to even my jbl boombox 3, the high bass sounds super strained and small and is mostly coming out of the bar itself while the subwoofer barely makes a sound(trust me it’s not my room acoustics, I practically put my face on the subwoofer) , and plays unpleasantly loud for the lowest frequencies(I’m aware it could be cuz of room acoustics but I brought it outside my house and it had the same characteristics as inside my doorstep. My subwoofer placement should be good as well due to the ports being well away from walls and making sure it’s not a dead spot using the subwoofer crawl, crawling around, only volume of bass deviates but high bass just never appears) . My LG SP9YA, though it didn’t have as good of a low bass extension, it’s high bass was super punchy and tight and sounds super good for music, whereas the Q990D is great for the music as well but is severely disappointing in the high bass department. The sad part about this is that the eq bands don’t go as low as the subwoofer frequencies so I can’t do anything about it, I noticed your frequency response measurements also show the around 60-70hz drop as well as the 300-400hz crater too and yall didn’t seem to comment on that. These ruins the soundbar performance for music imo, especially the 60-70hz crater, whereas the 300-400hz crater is less observable. If yall have any advice to rectify this it would be great. Also looking for more info about adaptive vs standard as I feel like adaptive mode ruins the clarity of voices in songs, but that’s less noticeable in movies while also being compensated by the much more immersive surround sound and height channel realism. Thanks a lot!
