Question to those happy with bass output - what volume level do you listen at? I use 15-18 and the bass is underwhelming.
I used a frequency sweep and an SPL meter, and credit to the 950, the output was relatively consistent db level down to 30Hz. It just isn't punchy with normal content.
I have the exact same experience and impressions. I run everything on +6 including the bass, besides the central speaker which is -3. I suppose in order to get added bass we could change into something like -6 on the central and +3 on the others and still have +6 on the subwoofer just to get it increased further compared to the rest.
But this isn't untypical behaviour. The intended dynamic range has been optimised around a specific volume level which tends to be really high. Of course it would, it's supposed to give you realism and entertainment. If a grande exploded right next to you in real life it would be loud, wouldn't it.
This is the whole purpose of DRC. You want to decrease the dynamic range so it better fits your intended volume. The idea is that you are trying to get the same feeling of peaks in the audio even at the lower volume. Of course the sub won't go as deep and give you the same punch at 10-15 volume as it would on 20-30. Same goes for the highs, they won't extended as much etc.. But by compressing the dynamic range you are saying that you don't want there to be the same gap and contrast applied, so it should let the bass go deep and the highs going high even at volume levels where they would not do so if the dynamic range was at it's default levels.
The range between the frequencies gets squashed/compressed so you won't need the same volume level to achieve the lowest and highest in the range.
Some might confuse DRC with things like "Night Mode", but features like various night modes don't only compress the dynamic range but they do also aggressively cuts out, especially the lower frequencies in order for the audio to be better suited for night watching if you don't intended to disturb others. Other firms like Sonos is calling DRC for "Loudness", but Loudness can mean different things. Sonos seems to only compress the dynamic range, but others like Apple seems to apply a EQ trying to not only decrease the DRC but also boost various frequencies to "spice" it further. I tend to prefer to have the frequencies unaltered and just the dynamic range compressed.
Yamaha has a really nice adaptive drc on their receivers where they will apply various degrees of drc depending on the volume level. Trying to achieve the audio to sound correct/best at all volume levels.
You get the opposite effect if you apply DRC + going loud on the volume. Then you get overly boosted low's and high's.
But this is just me rambling. It's just sad to see that Samsung dropped their rather extensive DRC implementation on the previous models on the HW-Nxxx series. I tend to listen on 8-15 and this would have benefited a lot by some DRC.
