Get the Best Bass for Your Home Theater P3: Wrapping it Up

[@jarodreddig63]

This deserves some kind of award for best series on KZbin!! I lucked out as my room happens to be 20ftx13ft so I was able to use your examples from all the past episodes for incredible results in my dedicated theater space! I have a 7.2 JTR system with dual JTR 18” subs in the front corners. For years a had a huge null, and turns out my seating was exactly 5 ft from the back wall. I corrected this by moving the row forward and installed and moved around my existing Acoustimac absorption and diffusion panels as Anthony had described and the end result was nothing short of spectacular! Bass is night and day better and so much more punchy. Sounds gigantic now and movie surround effects just swirl all around the room. Fast scary dynamics. I thought i would of had to hire out to get these results. Audyssey XT32 and app finally gave me great results too using your guide from a month or so back. Thanks a lot for all the help! I’m amazed. I’ve done this for years too but I learned so much from Anthony👍😎 Cheers.

[@everettspain2739]

This without a doubt is THE MOST HiFi education I've ever had in 30 years. I'm also STILL struggling to get good bass from all seating positions.

[@dilbyjones]

Yea..Gene has alot of it done from earlier vids

[@Hans-Larsson]

A REW training session - yes please 😊

[@christophergreen8069]

Yes please!

[@lawrence09151]

See home theater gurus episode 7

[@gillesvanleeuwen]

That would be very cool

[@jimmykaka89]

+1 for that just to see if anything is done different to HTG video episode 7 as mentioned below

[@TheRafcave]

That REW tutorial video would be outstanding Gene. 😉👍🏽

[@fahadalhbag1700]

It is already there, search and you shall find

[@Ibhenriksen]

Very nice presentation. But I want to add that in one of my rooms for the longest time, I just couldn't get rid of the boomy bass of my svs subwoofer. I tried everything! Calibrations, including REW, the crawl. Until I decided to move my front speakers around and it made a world of difference! So it's not always the subwoofer that is the culprit. It was my main fronts! Just wanted to add this in in case anyone is struggling like I was! Cheers ~

[@Ibhenriksen]

@@michaelkreisel3573 I didn't have a problem with the roll off but I tamed the reference level of my Denon to +5 and that really helped. Oh I have an svs 1000 pro. It's a smaller room.

[@Finite-Tuning]

Yeah, I'd really love to see a full tutorial on REW from you guys. The one already on this channel doesn't go deep enough. I don't care if it's 4 hours long, I'll watch it! I just re-tuned my system today after installing all this new sound treatment, I didn't know my room was causing so many issues until I compared the before and after treatment results. I tune different then most, I've learned to focus more on 0 degree measurements for tuning vs 90 degree. I'd like to talk a little about that when you guys hopefully make a full REW tutorial. I'm solid with the frequency sweeps, it's all the other bells and whistles that I'd like to learn more about in REW. Cheers guys 🍻.

[@TylerStout]

Wow just when I thought I had a pretty good understanding of everything I watch this and I still have a lot more to learn. I think my big takeaway was that I'm barely scratching the surface at what REW can do for me which is probably why I switched to MSO for optimization. There were so many parts where I felt Anthony could have dove in and talked for an hour but understandably he couldn't for time sake. Definitely putting another vote towards a more advanced REW training presentation as there's plenty that show the basics but they almost never focus on anything else besides the second tab in on the measurements. Definitely need to watch this one a couple times and really pause and dive in on parts.

[@stingber]

Great work guys!! Excellent content!! I use Smaart V8 with 8 Mic across my room. For tuning I use DBX 260 for subwoofers and Ashley Protea 4.8s for my LCR 3 way system. Sound is great!! I setup it using magnitude and phase for the crossover sections.

[@anthony2010707]

Thanks for a very informative video, good to see you are still going strong, keep up the good work.

[@kapooranuj]

Anthony..... Pls cover REW. REW. REW. The reason i say it thrice is because it needs beginer level, intermediate level and advanced leved (3) tutorials from you. I played with the umm6 + rew combo plugged into my avr but I'm not using even 5% of the potential of the setup.

[@kez2252]

Definitely appreciate all of the work here, and highly respect all of the knowledge you both have. That said, I do hope you put out a REW / minidsp tutorial as a supplement to this part 3, as this was very hard to follow and quite confusing. I've been heavily learning about bass management over the last few months and without some of that newfound knowledge, I would have been 100% lost and confused were I trying to apply any of the learnings from this episode (vs the 50% lost I was during the video). Delay adjustments where.... minidsp, sub, avr? Individual subs or as summed sub? Adjust in input or output of minidsp? Levels where...avr, sub gain, minidsp? A lot of intricacies that weren't covered. Phase versus delay adjustments, and where exactly to make them? Again, greatly appreciate the time and effort put in, and I now to the insane knowledge you each have. I also indersand it's a lot to cover in a relatively short video. However, if the goal is to educate the audience, then definitely need to reinforce with demonstrating the steps in REW and minidsp. Just wanted to provide candid feedback from a non expert fan of the channel who is trying to learn.

[@welderfixer]

I'm in the same boat as you. Adjusting all of this stuff is like piloting a 747, maybe worse. I have watched so many videos on using REW and very few go step-by-step. The big issue is every room is different and all rooms have different equipment and various levels of quality of equipment. So, there is no one size fits all. Trial and error is how this whole deal works. Experience like Anthony's is invaluable. If he takes 6 hours, we will take 24 hours. Here's a good video on REW-MiniDSP 2x4 HD I found that I can follow: kzbin.info/www/bejne/lavZeGOpaLiHjtE There is so many others I could list, but I can't step on Gene's toes here. He has done so much to help us over the years. Best of luck.

[@kez2252]

@@welderfixer thanks. That is actually one of the videos that helped me a lot as well. I hooked up the minidsp for the first time last weekend, and have only have about 3 weeks experience in REW so far. Enjoying the journey so far, and do sincerely appreciate all of the info Gene, and several others, have put out for us. I hope I didn't come off as an ungrateful viewer.

[@welderfixer]

@@kez2252 Ungrateful viewer? Absolutely not. Spot on post. All questions/requests/comments are great and help others. And, sometimes others help. Gene and his guests are a wealth of knowledge and I hope he can keep going just as I hope the same for so many others I watch, listen to and read. Unfortunately, It's so hard to put all of the info in an organized place for later use, but that is part of the fun of study. Have fun with your growing system.

[@kevinc7910]

Great info. Can’t wait to redo my REW calibration I did last year. Running 2 SVS 16 ULTRAS with a mini DSP. I think I know just enough to make me dangerous LOL.

[@maikvogel6632]

Thank You for all the Info's! Anthony should write a Book to preserve and share his Knowledge! Greetings from Germany, a new Patreon. ;-)

[@marcgras9064]

Perlisten apps can do all the trick. Delay, EQ and level and you can do it to all SW conected to the app up to 8 or individualy. It is a really great app.

[@1psxpat]

Good topic as always. I am wondering if you ever cover a topic for couple or decouple for subwoofer? it should be an interesting topic.

[@budgetaudiophile6048]

OMG! THANK YOU! Audyssey has RUINED my REW/MiniDSP responses in the past and I'm so glad to hear that I'm not "wrong" by telling it to piss off and leave me alone! HAHAHA!

[@jimmykaka89]

Another vote for REW tutorial too

[@PratyushNobeen]

Super super super informative. WOW! Thank YOU!

[@blswagger0764]

I had a huge dip at my 80hz crossover (up to 28db down from 65hz to 110hz) after spending hours in REW time aligning and EQ'ing my dual Rythmik F18 subs. I had the distance set to 9' based on actual distance. I played around with the distance setting in my AVR (Anthem MRX 1120) and the null was completely gone by changing the distance to 3'. My bass is now flat (with a 9db curve) down to 16hz. Next time I re-run room correction, I'm going to try the Time Alignment feature in REW to see what it says. I am still tempted to buy two more F18s to have a little more headroom and to help gain back the losses from turning on the limiter, rumble filter, and 14hz tune. I have a 7500+ cubic foot open floor space that opens to a hallway and staircase. I haven't done compression sweeps, but I am curious how loud my subs can go without compression or distortion.

[@harpsitardo]

God damn.. Anthony is a saint. To not go insane from the constant non-sequitor interruptions and questions from Gene and the Super Chats - all of which cut off Anthony right when he's getting to THE most important information: what a saint. But what a lost opportunity. Let the man speak!

[@jimmykaka89]

Mic drop when AG said not to set LFE at 120hz 😮😮

[@tomnwmi]

First I have heard about setting it at 80-90hz, I have it set at 100.

[@reznone6900]

At what time did he make the comment?

[@xXxkennedysxXx]

Thanks for this awesome videos. But to bad you didn't talk about double bass arrays (dba). Wouldn't it be the best and maybe even the easiest way to set up a dedicated rectangular home theater? I mean a working dba actually gets rid of every room mode. So a working dba has perfect amplitude and impulse response at every seat without any compromise.

[@markhouseholder]

What brand of eq or dsp are most of you guys using? Here for the 2 channel knowledge…. Thanks and love the series…

[@roccobruno8027]

Insightful as always.

[@wally6193]

Great series guys, but I'm a little disappointed that Tony never got to doing something for a 2 channel music setup(like he said he might at the beginning of this series) , you know for listening to real stereo music and not just movies sound tracks, haha. Gene, did you guys do another video with Tony for music setups?

[@vitalismunchen5740]

what about both woofers in the back? 1/4 wall each?

[@roco9504]

Wish I seen this live to ask with a super chat.. thoughts on higher end bass actuators such as Crowson’s?

[@buildmodrepeat2875]

Phi is another way of writing the golden ratio

[@CitadelRunner]

Question: If putting two subwoofers 1/4 of the way into the room is correct, why dont you also want to raise them off the floor by 25% of the ceiling height?

[@toddshagena4360]

Gene, That is a good question. If it makes a difference side to side and font to back, wouldn’t up and down also have an effect too?

[@CitadelRunner]

@@toddshagena4360 I would think it has to have an effect. But I wonder if that 25% factor is calculated using "subwoofers on the floor only". ??

[@jesusjoelgarcia8115]

Yoyo Anthony how about you fix your room for stater.

[@vitalismunchen5740]

with 1/4 off the wall ,you mean the driver middle point or just the side of the woofer? with my klipsch it makes 15cm difference if i choose the middle of the cone or the side ;)

[@audfrknaveen2256]

Getting Good SPL and Low freq extension alone may not guarantee great tactile feel. Near field sub gives tactile bass even at low spl. Anthony and Gene....if this observation is valid...what is the necessity of far field subs at all ??? Your expert advise is greatly appreciated !!!!! Thanks a ton for your videos. 😊😊

[@tankafer3127]

for users, REW, Rephase and Eqapo and for DIY speakers, Hornresp, Edge, VituixCAD not a word about double bass array ? (reverse polarity and delay rear sub for wave cancelation)

[@texxhexxmm]

When i have two woofers on one Side (Back) should i Put each 1/4 from Wall symmetrical or one in Corner or 1/3 and the other stays 1/4?

[@everettspain2739]

How much would it cost to get either of you (Anthony or Gene) to come out to my home and get my theater right? SERIOUSLY!!! I would literally pay for one of these guys or someone you'd recommend locally (Dallas, TX) to come to my home. I have a great system I paid a lot of money for and its not performing nearly as good as I know it can.

[@CrochetNewsNetwork]

Same here in Atlanta. I have the gear just need an expert to set up

[@LeadNarrator]

OK, this might sound like a dumb question. When making those frequency response graphs, or the data for them at least, does the data come from measuring pink noise or performing a frequency sweep? I'm confused on which of the two it is.

[@TheBarbapapa1234]

For setting up subwoofers you should use a frequency sweep from 0-200hz. You can set the time it takes for the sweep. I always set it at 10 seconds. So it takes 10 seconds to go from 0 to 200hz. That will result in accurate enough results most of the time. Good luck

[@dilbyjones]

Wow... The holy grail

[@vpont4184]

I made the mistake of buying a single monolith thx 10". My plan was to buy another thx 10", but now I'm thinking if I should buy monolith 12" or 13" instead to pair with the existing 10". The hunger just grew. The room is about 3500 cubic feet. I got the impression it's the easiest and best way to just have matching subs, but surely the 12" or 13" would give some advantage here also? What would be the correct choice here?

[@welderfixer]

Thank you gentlemen. I sure wish I could put all of this info to good use.

[@rl9579]

In an Atmos setup including two subs and full range LRC speakers, what would be the best speaker/ sub placement to start with. Can LRC be placed to cancel out rooom modes in combination with two dedicated subs?

[@valdeze]

Since they recommend it not to use Odyssey for distance, what distance should I set my combined subwoofers?

[@pabsgabs]

I'm using miniDSP 2x4HD. Should I set the processor to 0 feet for both subs, and set both subs to 0 phase, and then do everything from dsp? I usually tell the processor at what distance they are and set the sub in the rear to 180 degrees. Thank you!

[@akyhne]

I don't quite get the delay of subs. If you delay all the subs the same amount, I can't see how this would affect anything. I know that Anthony a few times mentioned adding a delay to the back subs alone, but it wasn't clear to me, if this was always the case. That would make sense.

[@TylerStout]

So generally speaking you want all your subs to hit the MLP at the same time so unless you're sitting exact same distance from them you'll need to delay certain ones so they do. Main reason he mentioned delaying the back subs alone was because generally you are sitting closer to them then the front ones. Home theater gurus does it by picking the farthest subwoofer and adding subwoofers one at a time and delaying till you get a good response or you could align front pair together then back pair together then combine both together and see how works together with different delays.

[@Stevo19801]

Gene, I noticed in Anthony reference room response curve that the bass tailed off after about 30hz, commercial theatres also do this from about 40hz and I have seen other high end designers do this. Is this his preference, as I Imagine the gear in his reference room is not limited?

[@Audioholics]

I believe that was for his main speakers, not the subwoofer channel but we can ask him next livestream.

[@joekool5676]

Do you recommend certain brands of subwoofers?

[@CrochetNewsNetwork]

I do. REL. However I’m sure I can even get more efficient with this info

[@deanberdon2572]

Does anyone offer remotely helping to set up subwoofers? I understand there would be a charge for this

[@NES088]

[@toxicdragon346]

I have a SVS PB13 ultra and will it work well with a SVS PB16 ultra? I want a second sub but they don’t sell the 13 anymore

[@joedirt6222]

The pb 4000 will pair with the pb13. Svs also has an upgrade kit (basically a new amp) that will bump the power up on the pb13 to more closely match the 4000 series. This upgrade also allows the pb13 to be controlled by the Svs app. Best to message svs customer service and they can provide more complete info.

[@Astro-ck6mh]

I'm a very simple man. 5.1 system only... can I just run the audyssey xt32 calibration off of the denon avr and call it a day? Does it do a decent job?

I see that Sound United now bought B&W too, so they now own Marantz, Denon, Classe, Polk, Onkyo, Integra, Pioneer, and B&W. And, they seem to be doing nothing with Onkyo, Integra, and Pioneer, they're just letting them die.

[@Audioholics]

SU never completed the deal to buy Pioneer or Onkyo.

[@TylerStout]

Like Gene said that deal didn't pass and Onkyo/Pioneer announced new 2021 AVRs with Dirac so not sure why you think they are dying. If anything they will be more competitive than they have been in a long while!

[@thr0nic]

There are people on r/WeAreTheMusicMakers with flairs "Mastering engineer" that will fight you on their opinion that multiple subwoofers will only make modes worse. They believe adding subwoofers anywhere will have no effect on nulls and only make peaks worse. How does Grimani argue with these types of people? Or does he just agree and continue his day. I don't think italian people does that 😅😅

JBL cinema professional in my small yet x158 JBL with legit cinema THX at 38.000kw. REW is connected to the THX 3417 and any outboard in-room multi microphones to use all at same time or mute any mic and see the results with on-screen to make decisions or move the mic a little bit as it maybe in error of placement or I can use the THX amp return with spectrum lab and listen and feel for those bass notes, but I now rarely care for my THX JBL home cinema, life has changed since 2020 for the worse yet most act like nothing has happened and only care about a plastic home theatre. When you have lost an uncle, then your Dad and then your cat, cos boris is locking down everything where vets can't treat my cat and offer a sleeping option which isn't even an option.
