Expert Audio Series - Speaker and Room Layouts Part 1 

Grimani is the best. Truly incredible presentations. 30 years of expertise perfectly condensed into a few hours.

had to stop everything to watch this quality content - thanks!

Ever since seeing Anthony on the Audioholics series of videos I’ve been searching for other material with him featured in it and came across your channel. Excellent upload!

I have a 5.1.2 and originally had my .2 as heights on the front wall. Wasn’t super impressed but noticed the sound was bigger (not necessarily better though). So later I reinstalled as center ceilings; still not convinced. BUT I had them in line with front left and right per Dolby’s diagram…. Until tonight. I moved each in just 6 inches, and i shit you not, my freakin jaw is still on the floor with how much more immersive it is. After 2 years of dickin around I finally got the atmos bubble I’ve been looking for. Thank you guys so much!!!

Hopefully at last this is the ONE! I'm forever changing my speakers and seat positions and never seem to be completely satisfied. How ever recently I did go with a set up suggested by an article on line which is working well but with all the detailed information in this video all of the questions that I have ever had regarding set up seem to be answered so I will reposition everything based on this video. Great work guys!

This is such a top tier video. I'm going projector so I'm redoing my speaker layout and this is just more great info from Mr. Grimani that will help make my system sound BEAST!!!! Thanks!

Great video

Hi thanks for this amazing video. I have a 9.4.6 HT trinnov system. I am having a dip in the 125hz with my L and R speaker. The C is fine. Speaker are toe in and about 5cm from the front wall at 44° Room is heavy threated, 4 bass trap in corner. 5cm absortion in all 1st reflection

Wow, soo much info and it came just in time. I'm planning on building a Theather in the living room, i know it's not ideal but there are no other rooms to do it. Learned about the distance between a woven screen and speakers, a bit of crossover and MTM pros and cons. (yes i will DIY my speakers too). I'm planing on watching part 2 tomorrow and on saturday. I don't know if there will be an answer to my question there so i'm gonna ask it here anyway. Ok an MTM has it's problems, but i can't do a TM only because the 8 inch woofer that i plan to use won't be able to reach reference (105db at listening position), and doing a MTM with 10 inch woofers is out of the question, the horn and the 8 inch will take soo much space and in the living room not happening. So what if i use a 10 inch coaxial driver ? I know there are problems with that because the cone acts as a wave guide that moves up and down and messes with sound badly, that's why i avoid planing a coaxial driver design, but i wanted to hear your opinion on that also.

Great video. Designing my second theater and hopefully am fixing some errors I made the first go around. Near the beginning of the video, it was suggested to use a 50 degree viewing angle. Is this comment true for both 16:9 and 2.39:1? I have been planning on using a 130" AT screen at an 11-11.5 foot seating distance to the MLP which as I recall will give me a view angle of about 45 degrees. Going up to a 140" screen puts me at the 50 degrees. This is for a 16:9 screen. Thanks for the clarification.

How to get rid of the dip? Closer to the wall? Another question many people says for stereo pulling the speaker further away from the front wall gives best soundstage and imaging. This practise is different than home cinema. How to get both? Thank you

Anyone know which processor he is talking about that does not send a signal to the upper middle speakers when you are using the wides? It is mentioned between 37 and 39 minutes. I am researching a 9.X.6 system to purchase and this seems important.

46:30 well height channels are used in object based audio, but you can have more bed channels than the 7 channels. So the wides are wides but what would we call the speaker between the wide and the side, or between the side and the back. You can have up to 22 bed channels, same naming problem.

38:25 Anthony prefers 9.x.2 over 9.x.4 for smaller rooms. On forums I see most people having a different opinion, favoring 5.x.4 over Rear or Wide speakers. I wonder what other people think on upgrade paths and what Anthony's prefers too 48:10.

"Add 1/2" foam to the entire front baffle" I don't get it, what is that for and how? thanks, great video!

Can Front Wides be matrixed from ANY soundtrack, from a regular 5.1 to an Atmos or DTS-X track that doesn't already feature Wides in the bed layer?

Should surrounds be used for a room that is 25 ft long bit only 12 ft wide? If so should they be dipole? Also how atmos that this space, 2 or 4? Ceiling height is 8.5 ft

Also why he talked about the flawed MTM centers but not of the MUCH MUCH better 3-way centers???

What height the side,wide and backs from finished floor level

i'm at point for the talk of the wide speakers. Wides can only be used in a Atmos based movie, (DTS-X is limited to 7.1.4 so no wides). And most Atmos movies don't have that many objects (for BDs) anyway so the wides are almost never used. Standard 7.1 mixes also can't put sound into the wides. Is there a trick or something to make them work ? EDIT: ok i'm at the 49:52 minute mark. Well yes objects can be placed at the wides, but the problem is that Atmos for home can only store 16 objects ? so the wides won't be used that much. Also many people on forums that have wides say that they almost never hear sound coming from them even thou their AVR or AV pre-pro says it support wides. And and, most Atmos movies don't take the full potential of the object based audio, they just add enough to add the marking label on the disk. =/ Maybe we should ditch the normal way of mixing audio and do everything with object, this way we can force the studio to produce proper audio. But this will cause soo many problems on the consumer level. Maybe i will find the answers later in the stream, gotta go to bed so will try to finish the last hour tomorrow :). Really love these.I will probably watch all your videos.

Hopefully Anthony Grimani sees this, but the in-wall speakers with pivoting drivers (mid and tweeter) is Monitor Audio

I have small room with no 4th. wall

Can you guys tell me, if my room is 21x19, my RX-a2080 can do 9 channel, which would I benefit more from, 5.2.4 or 7.2.2? Is it right to think that there is less to benefit from rear speakers then 4 ceilings?

Isn't the most ideal set-up of Front LCR a equilateral one? Meaning the front left and front right are the same distance from each other as the Centre speaker is from the MLP? and the angle is 60 deg between MLP and front right & front left?

Br = Back right speaker but also Back right subwoofer

Dolby spec for height is more to the sides and 45 degree not 30. Getting it closer will lose depth. Also would disagree on other speakers spread. LR set at 30 and you’ll notice big difference. Rest on each side spread every 40 degrees so 70 FW 110 Surround 150 surround back and each speaker is given even 40 degrees for sound dispersion. Also for stereo music 30 degrees (from center) with my speakers gives bigger soundstage than suggested 22.5 (45). Next center speaker position: yes you can angle center speaker at you and there is probably max angle that you should not exceed if you want sound to by attached to screen. Not distance between LR and center but angle of center. 2 feet will mean little if you sit 18 feet away. 1 feet will mean a lot if you sit 6 feet away. It’s about angles to your MLP not distances between.

The recommended viewing angle is 30 degrees according to calculators online, not 50 degrees? 🤔

Bye

This is absurd. Why would you want 65º of separation from Side Left to Back Left yet only 30º between Back Left and Back Right?!!! You can do much better creating a better gap between the rears to allow some panning while also solidifying the imaging between sides and rears. Also he saying the top fronts can be 20-30 degrees forward from you is missing one KEY element...ceiling height. If you are limited like 8 feet or less, 20 degrees will place them so close to you, that you may as well just use 2 atmos instead of 4. How much forward they will be placed is affected by your ceiling height so he cannot just throw some numbers like that.

I love how he exposed how absurd the theory of evolution is, at 40:20. If evolution is true, then the offspring of Atmos listeners should be born with tiny little ears at the top of their heads, and these ears should gradually grow larger with each new generation of offspring!

A lot of bullshit is spread here. Professional installers from the home theater sector have made a lot of tests here and gained a lot of experience in practice. It is absolute nonsense to install the front speakers at 22 instead of 30 degrees.
