@@timg3580 thanks. I’ve got a bunch more videos coming out on a family room, open concept system and how I solve the acoustic and reflection issues. Then I have a simpler 5.2 system built from Sonos, and then finally a full walkthrough of my theater build, although I’m just starting the design on that one, so I’m pushing for around CEDIA or shortly after. If there are any questions, or content you’d like to see, just let me know.
Appreciate the support. I've got another video coming out in the next week or two on AES67 and Dante, as well as a lighting tutorial series on whole home lighting, but you know I'm gonna do something special for my theater as well...
Agreed. The house I recently bought has more than 100 switches and only two dimmers... Actually have a delivery of more than 100 lights from Proluxe coming today. They do some great bulbs and linear lighting for a reasonable amount. I'm also getting ready to put an order in for some Lutron Ketra lighting for the areas I really want to show off. I expect to build a 10-part series, with overall education, and then room-by-room demonstration. Always appreciate the support KR.
I know this video is a bit old however still really really informative and well done. Thanks for that. Question: did you use a DBA setup for the subwoofers or were they all same polarity and the back not additionaly delayed by the distance from the front Subwoofers to absorb the standing wawes coming from the front? Thanks a lot for an answer. 😊
Great question. Each sub is aligned for polarity and time delay in order to get the cleanest sound. By positioning them into the corners, you get the most gain out of the subs, but by having a sub in each corner, and adjusting for time and polarity, you are generally able to cancel out most standing or modal waves in the room. Since that covers the general bass in the room, we then layered in one Infrasonic sub. Only one was needed in this room for pressurization, and because lower notes are so long, they don't really have the same issues with modal waves. Hope that helps. Once I get my new theater done, I'll have it initially setup with a Storm Processor because there is a lot it can do that the Trinnov can't, but I will likely borrow one to compare Waveforming vs. Dirac ART vs. just polarity and time aligning the subs in four corners. I think there is a lot of fanboy love for one brand or another because it's probably the first time the room had a processor capable of doing the proper calculations, but I'm curious how they stack up objectively, or what I think will happen is that they effectively do the same thing in different ways, at which point the answer is which one is easier to execute in your room.
Still runs through my play list. Guitar is signed by Slash after I helped him with some rack stuff, and the Beatles album is from a private tour at Abbey Road when I was at B&W. Harmony remote was one I designed, as were the headphones. Porsche helmet for track days, which may not be in frame. A few of the things that mean a lot to me. Appreciate the watch and the comment.
Very interesting point at 57:00 into video. . almost exactly size of theater Grimani/MSR finished last year for home. Wish had bigger but makes sense about the price curve not being linear once you go past that volume mentioned. Theater done but fun to keep learning and advancing knowledge!
Yesh, bigger is always nice, but the curve rises dramatically. And for a lot of people, they add in a bunch of extra seats that don't always get used. Nice to know they are there, but better to invest in quality over quantity sometimes as well. I hope you are enjoying your theater. We may need to do a video of it at some point. I think you mentioned in a comment to Youthman before that you'd be open to it?
@@faqnatics Yeah we have some movie nights with friends and family where it'd be nice to have a few extra seats but then the space would be overly crammed and not optimized. Also, would be happy to have video shot. It's a pretty straightforward theater as we just did stretched fabric with Colorbeam vertical linear lights and low-back recliners to keep the focus on the screen and not any effects like shooting stars, etc. I mentioned to Trevor at an event a few weeks back I'd be glad to have him or anyone else come by and demo or video anything he wanted as he had some colleagues from Australia visit before CEDIA last year. Would be glad to do same with Michael as well since mentioned it to him at CEDIA also. I'll see him at MWAVE in June as well.
What if you use more than two rear channel speakers (3 or 4). Would the measurements regarding the sound place be similar or just separate the four into two zones...
@michael, just to clarify, are we discussing the comment from Anthony about having a narrower setup of the rear surrounds, or something else? Also are you saying that you have 3-4 speakers on your back wall, or are we discussing rear wall and side surrounds that are further back? Here's a good resource from Trinnov a while back on speakers placement. Every room is a bit different, then you have whether we are discussing Atmos or DTS preferences. This document has most of those things covered, and you can start around page 15. drive.google.com/file/d/1qFpM5c9_n_0PU6EcW-J5qFvf4QDWqjg3/view Clarify the setup if you want to discuss, otherwise that document should get you started as well.
@@faqnatics Yes sir! I'm referring to the back wall setup...I know it depends on the room dimensions... However, the plans for the new build w/dedicated Theater (21x30x12).
@@stefanbrathwaite2130 you mean the frame we used to cover the speakers? Assuming so, that was made custom by Evan Zerby of Seymour Screen excellence. He’s got some amazing building skills. Effectively the frame has a fabric tuck attached to it. You could do the same with wooden frame, or build it with an aluminum frame
I’ll ask Trevor on Grimani’s sales team, and I’m sure I can get an answer for you. It’s a Sunday so just give me a day or two. Any idea on how many you’d need?
So the treatments used in this build are MSR, which is Anthony's acoustics company. Great product, and I've included a link to the pages here: www.msr-inc.com/home_theater/hometheater.html It could use some updates, but I can connect you to their sales team if you wanted more information. Effectively though, the walls and ceilings were 24"x48"x4" in order to actually absorb down to about 250Hz. Anything shallower than that, and you are really only absorbing the high frequencies. and not taming the bass at all. The front set of sidewall diffusers were horizontal, and the remaining side, rear, and ceiling diffusers were randomizing diffusers. They are plastic in this case. and we added a bit of absorption material behind them. However, these are meant to sound great, but also need to minimize packing space and weight since it's a temporary solution. These work great, but more solid diffusion solutions are available that do as good or better of a job, but at a more premium price. I will likely be doing a video on acoustics soon, so if you didn't yet. please like and subscribe so I know it's a topic people want to see.
That's not too bad of a room. Unfortunately. you are probably going to be capped at 2-3 seats in the room, so I'd recommend going with a couch to add more seating without as much width. Any chance the room is in an attic space, where the side walls are open behind, rather. than with a wall on the other side? If so you can use fabric walls like me, and place the speakers inside the wall cavities, so they don't take up space in the room. I'll be documenting my room build in November and December once I get over my COVID from CEDIA, and finish my family room project. I you don't have open space behind the walls, go with a good in-wall speakers with an included back-box, so that again, you can. get those seats as far away from the speakers as possible.
@@faqnatics Hope you recover soon! I had COVID about 2-3 months ago, and it felt like getting hit by a truck. It took at least 1-2 months to fully recover. My room has concrete walls since I live in a high-rise building in Taiwan. You're right-I might only fit 2 seats in the room, probably positioned around 3 meters away from the screen. I'm planning to use a Barco Bragi projector with DT's AT screen, about 130". For speakers, I'm considering Wisdom Audio P38m point source speakers for LCR, along with Sage Series 2 V2 point source speakers for the surrounds and Atmos channels (based on their website, they can be used in/on-wall and ceiling). Your room build will show in this channel?
Let me see what I can get from him in regards to this, and I'll try to rewatch to see if I can find the point you are referencing. I know at one point we were talking about the rear surrounds being wider, because having them directly behind you often confused the brain into thinking it was in front of you because of the directionality of where it hits the ears. I'll ask him and in the meantime give it a watch to see if I can better clarify the points made.
@faqnatics yes, for rear surrounds he recommends 165degs, much closer than the Dolby spec. My point was about the Atmos center pair, it's wider in the plan than the front and rear Atmos speakers.
Hmmm, I will check it out. To be fair, not much has been added yet, and I know I check the box to alert subscribers. I’ll check the settings again though, appreciate the heads up.
@@matta9316 okay. I’ll double check and make sure especially on the next video. Can’t leave my fans waiting… but just make sure you check back on the page each week anyways… 😉🤣🥃
As a VIP heads up, I have a new video dropping today on networked audio. It's actually an interesting watch on what will likely be the future of audio. This way you can see when the notification comes, and either way I wanted to make sure I told you! ; )
Fantastic video and interview. Grimani is such a good teacher & communicator in the way he explains things.
