The space for 7.1 is too demanding. I have doubts about Sennheiser Ambeo, too.

According to Sennheiser, the effect is best if the
Sennheiser recommends installing the speaker
- walls and ceiling are no more than five meters (about 16 feet) from the soundbar;
- otherwise, the reflected sound might be noticeably delayed.
All listener speakers should be at the same height,
- in the center of a wall
- at least 39 inches (1 meter) from
- the side walls or
- ceiling.
- You have to give this thing room to work, so if you can't do that,
- this probably isn't the soundbar for you.
- typically 3.9 feet (1.2 meters),
- which is ear level for the average seated listener (as defined in ITU-R BS. 1116-1).
- If possible, the height of the rear speakers should be the same as the height of the front speakers.
HDMI 2.1 is the latest version. It allows streaming of advanced surround sound formats like Dolby Atmos and DTS:X and supports 8K video.
For speakers:
While two Dolby Atmos-enabled speakers, modules, or overhead speakers will deliver a compelling experience, we recommend using four if possible. This will deliver more precisely located and realistic overhead sounds. ... Dolby Atmos speaker layouts parallel the 5.1 and 7.1 setups for surround sound. A 5.1.
- Minimum Layout Length: 3.5 meters (= distance from Center baffle to your back-surround line)\
- Minimum Layout Width: 3.0 meters (= distance between you side-surround speakers). \
- Minimum LayoutHeight: 2.4 meters (= distance measured from the floor at mix position to the acoustic center of your overhead speakers)May 18, 2021
DTS is encoded at a higher bit-rate and therefore is considered by some experts to be better quality. Others argue that Dolby Digital's technology is more advanced and produces better sound quality at a lower bit-rate.4 days ago
With Dolby Digital, when an illusion of someone behind the audience needs to be created, the sound is simply thrown to the intended speaker. This is because Dolby Digital is a speaker-based system. Dolby Atmos, on the other hand, does not push the sound to a certain speaker. Instead, it pushes the sound to a 3D space.
Compromised Sound as an Evaluation Technique
Perfect sound reproduction does not exist. The extent to which sound is compromised is a more realistic appraisal. Reflective surfaces are key to Dolby Atmos performance.
I believe a high degree of compromise exists in my bedroom for fully immersive sound (7.1.4), based on software intuition,
- -2, on a scale from +3 to -3
- The ceiling fan will scatter reflected sound.
- The irregular, recessed nook in one half of one wall.
- The irregular notch near one door
- The six-foot (2m) knee wall that is open from three feet (1m) from the ceiling.
- LWH ratios necessary to fully exploit Sennheiser Ambeo technology.
- I cannot position myself in the center of the room, on my bed.
- The room dimensions are too small.
- My head is close a wall.
- -1, on a scale from -3 to +3
- The degree of compromise is determined by DSP capability.
- I really do not know what the actual DSP result will be.
- My guess is the improvement would be limited to +1, on a scale from -3 to +3.
- I really do not know what the actual DSP result will be.
- My guess, based on software intuition, is my bedroom does not provide the
- regularity of reflective surfaces
- LWH ratios necessary to fully exploit Sennheiser Ambeo technology.
- I am unwilling to bet on a $2500 soundbar.
- The six Sennheiser Ambeo 4 inch, long throw woofers are unfamiliar technology to me.
- Two subwoofers are probably necessary.
- One subwoofer sounds very unbalanced, because it can only be placed near a wall.
A 2.1 audio system is the highest degree of compromise that I can expect for my situation.
- Specifically, about a
- 2m to 3m listening triangle
- Closer to 2m than 3m, based on the choices in the following table.
- Online store return policy compromises to 1.5m to 2.0m.

- The upgraded 8351B now offers increased SPL,
- additional room compensation EQs,
- equalised delay and
- enhanced HF response.

- The following table is useful to begin trading off compromises.
- Immediately, the race track shape (13m x 5m x 3m, LWH) of my space compromises my choices.
- Trade off distance from speaker against room volume.
- Immediately, the race track shape (13m x 5m x 3m, LWH) of my space compromises my choices.
- The Important Notice This item is noncancelable and nonreturnable is the second compromise.
