Wow! Thank you for answering my question! I really appreciate you taking the time to explain THX standards. That was very helpful!
No problem! Glad you enjoyed it.
Extremely helpful! Puts a lot into perspective for me from an expert in the field. Thanks!
Thank you.
Thanks for taking time to answer my question.
Awesome info. Thanks
Great video! I like this format more than the super chat-like questions you tried before.
That was very helpful!
Thanks for taking the time to answer
Glad it was helpful!
Haven't been able to watch but I like how large your name is on the thumbnail...star power! We need to get that calibration in asap btw sir!
Love the content!
Hi Matt if you have time can you clarify if the R5i-LR's did manage to get the Dominus rating? Just on Perlisten's website it says: "the R5i-LR is THX Dominus surround and Ultra LCR certified"
I'll be installing my R5i-LR's on LCR duty in the next few months & always thought they were only Ultra rated, not that it really makes any difference in my small sized room but it's just interesting to know these things about your equipment 😁
I checked, you are right, it is not Dominus rated as an LCR. It is Dominus rated as a surround. Looks like only the S5i was able to achieve the Dominus rating. Sorry for any confusion.
@@PoesAcoustics Thanks for the clarification 😁. As I say I only have a small room (aprox 50 m3) so Ultra should be more than enough!
Geoffrey from Ascendo said it best in regards to thx. How do you have a rating system based on measurement and standards but you won’t disclose the standards.
Thanks for the information. It always adds value.
They have accidentally disclosed them actually, but sadly if you blinked you missed it. They had a short lived website that reviewed and rated products they had tested. It laid out the criteria, which just so happened to be how THX products are tested. So if you saw that site, you could figure out what the criteria were.
We roughly know what the criteria are at this point and from that can tell that the standards are actually extremly stringent. What I would tell people is this: A THX rated speaker is a good speaker, we know it is because of how stringent that criteria is. However, that doesn't mean another speaker without the rating isn't also good. Instead, we simply don't know unless they provide third party verified data. In the case of Ascendo, they provide Klippel reports that they themselves did not take, but a third party company did. So...if you know how to read them, you can tell if those speakers would achieve the criteria. Many of the Ascendo speakers would fail the smoothness flatness requirements, but pass in every other way. The nice thing about Geoffrey's speakers is that simple eq fixes the smoothness issue and you have a product that is excellent for home theater use.
@@PoesAcoustics appreciate the response Matt. Very informative.
I have 2 questions that I think would be good topics
1. For inwall LCR, is there any benefit to toe in your left and right if sitting distance place you 22 to 30 degrees off axis. And you speakers have very good horizontal off axis response. Think Kef or perlisten. Of course the toe in would ideally be baffle mounted to avoid sbir
2. For the main left and right. What are your thoughts on going wider than 22.5 off center. 30 to 45 degrees. Of course 45 would be the extreme and may not
be possible based on room width
Something is up with the audio here. Breathing sounds only in the right channel, making them stick out. I wonder why that is 🤔
I think that is my fault. I had changed the Dji mic to do each mic on a different channel. I never reset it and I didn't tell my wife to make the sound mono. I don't know why it made a breathing sound on the other channel, but that must have been the noise it recorded?
When I play it back on my laptop, I don't hear it. I'll listen with headphones later to see what is going on. Sorry that happened. We actually shot a real "part 1" to this that I had to scrap, the focus was messed up, so I will reshoot and check the sound settings.
Hey very cool, new subscriber here 🎉
Thanks for the sub!
Is there a way using REW or other free /cheap methods to know if a room would benefit from some diffusion?
Kind of, but the Texture analyzer software is the better method. Email me if you want to learn more. For a modest fee for my time, I can take REW meausrements that you have taken and then analze them for this.
Needing diffusion from measurements would look like strong peaks in the ETC. It can be infurred from the shape of the EDT. Having sufficient diffusion would generally show up in the ETC has having no strong peaks necessarily with a right triangle shape to each one and...if you zoomed out, a wedghe shape after the initial peak. Small rooms don't always look just like that.
But to really get into understanding and analyzing it, the Texture analyzer would be the most correct way to objectively look at this. Which...keep in mind, is a new concept that has not gone through rigerous subjective testing. The biggest next test is to correlate texture scores with perceived sound quality of a room and that hasn't been able to happen yet.
At the same time, any room could benefit from diffusion.
Can we see measurements on GuD panels?
I thought I did that once before, but if not, sure. I can bring up the measurements on my computer for a video and show you.
@@PoesAcoustics you showed them during your home theater build and then said you’d have a subsequent follow up video. I’m sure you were busy. But it would be great to see the impact on REW with those diffusers. They are supposed to work at a short distance
@@joek6207 oh I see. Showing the impact of diffusers within REW is extremely difficult. At best it would just make strong peaks in the ETC less strong and spread the energy out over time a little more.
I can certainly show some room analysis that is suggestive of the impact of diffusers. My ETC is very clean for the sized room I have.
@@PoesAcousticsthat makes sense and would provide value unto itself!
Dolby has always been a dragdown for the audio industry imo.
Yeah I can understand that perspective, but what else do we have. They were the savior. At one time cinema sound was awful and varied greatly. THX, Dolby, and a bunch of caring industry insiders helped change forever what we think of as cinema. Dolby is now among the oldest remaining in that part of the industry and they want to own the industry. So I get the concerns, but...DTS is on the rise, Auro never really had much of a shot, and I'm generally Ok with where things stand right now.
What is a good panel?
GUD panel is probably what you mean. It's a new type of optimized QRD diffuser from Real Acoustix that achieves extremly high diffusion.
@@PoesAcoustics Got it thx.
Didn’t answer my question but okay… 👌🏻😅
I am not a fan of sweets actually :)
I think you brain washed Gene. I love the Directional vs Mono Bass Management - What the Science Says with Todd Whelti. Denon / Marantz and Audyssey work together with Directional Bass zone feature. Hope Dirac updates there code to support the same.
Pop the cover off a Marantz AV10 and a Trinov and let Gene test bench the components and SINAD. The AV10 looks like one of Matts 2022 high end Mercedes. A Trinov looks like a Microcenter ATX motherboard with some Sound Blaster audio cards.
That is not correct at all. The Analog board on the Trinnov is not a soundcard (and I am guessing you have never seen the isnide of one from that comment.
We did test the Marantz and have tested the Trinnov in the past. The trinnov is slightly better than the Marantz. It's main advantage is that its a far far more flexible processor.
I am completely confused what you are saying in the first part. Dirac won't be updating their code to work with directional bass because its not an approach they support. Todd Welti doesn't either. As for Audyssey supporting it, that is only because its not summing the bass to mono, it corrects them individually. A sure fire way to get bad results.
@@PoesAcoustics I hang on every word of the Audioholics chief contributors. Gene loved the discontinued Denon AVP-A1HDCI & POA-A1HDCI Separates. The insides and bench measurements blew his mind. Roger Dressler from Dolby Labs will not upgrade his Classe Delta SSP-800 AV Surround Sound Preamp/Processor. He just won't re would rather matrix redigtize ceiling speakers from True HD Blue-rays.
My point is the insides of the Japanese made AV10 is better than an Anthem AVM90. Just the configuration and audiophile grade of equipment.
Honestly if Sony 360 Spatial Sound Mapping DSP and steering is Trinov quality. Why they don't license to Denon and Marantz baffles me. Or why they make a successor to the Yamaha CX-A processor made in Japan. I miss the sparkle DSP of the Sony's and Yamahas DSP and steering. Marantz can't do that.
@@chebrubin my limited understanding is Sony 360ssm is competing against denon/marantz as they use Auro3D upmixer Auromatic. I have a denon 3800 and really dig the auro for poor atmos movies. But I bought a Sony 7000 just for the 360SSM which is similar and I really like as well. To attempt a guess at your question my answer would be Sony is competing with denon and that is why they don't liscense 360ssm to denon/marantz.
On another note Sony does have the similar sounding tech as you prob know that they are selling to denon/marantz. Sony 360 Reality Audio, which is nothing related to 360SSM, is a spatial audio format that I read denon will be receiving an update for since it has mpegH. Btw I like 360RA as well its similar to Atmos music.
