001 Loudspeaker placement (long version) 

This is the best and most informative video about speaker placement I have ever seen. Thank you

"there are more costly solution but they lead to costly divorce..." hahaha You say it so seriously i had to repeat it to make sure thats what you said.

This is the best explanation about audio I have ever heard

Also I want to say how nice it is to watch a YT video that the sound levels aren't totally messed up.

Finally a practical approach instead of the usual esoteric twaddle and impracticable advice that is found on youTube too often; Thanks Hans!

I’m still working on the walls of the outer room of my room within a room. It’s going to be a challenge to tame and I might have to accept that I won’t ever have a fantastic room, but it’s videos like yours that keep my spirits high! Thank you.

Great video, I have always noticed speaker positioning makes a huge difference

THE best video on speaker placement! Bedankt Hans ;)

One, Hans knows what he's talking about. Two, more importantly, he can explain in a manner that can be understood. I would have loved more examples but This was perfect.

Nice to know the maths involved in speaker placement...Thanks Hans

Great video. One more point regarding fully dampened rooms not being ideal to listen to what the music production team had in mind: let's not forget that mixes are done in studio rooms that also have some reverb and early reflections. Yes, studios are well treated acoustically to be as neutral as possible but it doesn't mean they are not live. Therefore you are right in saying that too much dampening is not advisable.

Thank you very much. I am not english and I have understand all easily cause you speak very well. You are a very good teacher, I have learn a lot as an amateur and you have keep me super interested all the time. One of the best video I have see from long time. It's clear that your purpose is to teach others about what you master and love. Thank you, it's a real pleasure to see a video of this quality ;)

I've watched dozens of videos on speaker placement and this one is, without question, the most informative and practical one I have seen. I especially liked the visual aids. They make it easy to understand the concepts.

Fantastic video witch explains beautifully and succeed in cutting in pieces this very complex science and succeed in destroying the myths that plague the conversations. Focuses on broad questions, and give general answers that always show the diversity of rooms, and remain valid in different cases.

As a complete beginner just having bought his first pair of monitors, this video both gives me exactly the information I was looking for and introduces new concepts to pique my interest in the hobby. All the while maintaining an unpretentious and entertaining delivery. Subscribed!

thanks for the info involving halls, you're the first to mention it.

"There are also costly professional solutions, but they often result in even more costly divorces."

Mijn geluid vóór Hans Beekhuyzen: ¡ No bueno! Mijn geluid na deze video: Perfect! Dank je wel Hans. Zeer rustig en helder uitgelegd, en dit werkt 100%, echt heel blij mee.

Thanks for this excellent presentation

Most informative audio thing I've ever heard, seen or even read. Highly appreciated. Even a dummy like me was able to really grasp this for the first time, even though I've read and watched a million things prior. Much appreciated my friend. Subbed.

Excellent. By far the most important thing most people (with more than extremely poor/cheap reproduction) can do to improve their sound. Great to see an audiophile/hifi-er stressing this.

this video is one of the best i've seen,period.

Thank you! I've been using this method in setting up a listening room prior to pick the best suited series for quite sometimes. This video have describe the theory of room acoustics the simplest and most comprehensive way.👍

Thanks Hans, just bought a new stereo and this video was not only a good review of acoustics but you covered all of my questions about speaker placement! Very excellent! Thanks 👍🏻

With so much misinformation out there, it is great to hear someone explain room acoustics accurately and in an easy to understand way. His explanation, including visuals, of room modes is better than I have ever been able to explain to clients. One suggestion, for those creating a room for audio reproduction, not only should the room proportions not be multiples of each other, but the construction of each wall/floor/ceiling system should be such that they do not resonate at the same frequency.

Congratulations for your work ! Actually in these days I'm looking for a new pair of speakers and I haven't already realized what ti buy. Moreover I' ve got a very particular shaped room; and your tips which are both interesting and practical will help me a lot ! So I will adapt the room first.... the speakers come after.

Weer iets wijzer wat speaker plaatsing betreft, bedankt voor de tips en uitleg simpel en doeltreffend !

Beste Hans, wat een geweldig kanaal! Tussen alle zogenaamde reviews en unboxing videos iemand met een degelijk verhaal en verstand van zaken. Top!

The best explanations I have ever heard.

Amazing..... The video not only explains the techniques of correct speaker placement but also beautifully explains the reason behind each technique in a simple and easy to understand manner... Not seen a better tutorial yet in you tube.... Thanks a ton....

Helpful - thank you. Might be even more helpful to subscribers to also cover the potential advantages of 45 degree toe-in: 1. Greatly widens the sweet spot for outstanding sound staging - you don't have to worry so much about sitting exactly in the middle - very useful for multiple listeners or when you are moving about the room while listening too; [As you move to the left you are closer to the left speaker but more off-axis, and further from the right speaker but more on-axis] 2. Can help reduce or virtually eliminate early reflection problems from side walls, (depending on the room of course); 3. Can reduce treble without having to resort to tone controls, which can be a very good thing when using resolving sound systems (such as high-end studio monitor / dac combinations). If you haven't done so, try it!

I just found this video and am now kicking myself, this easily one of the most informative speaker placement videos I've ever seen 👏 👌 🙌 😀 thank you.

20:19 Amazing.

Wonderful presentation. As a audio tech of some sort I was impressed with your ability to express a technical observation in terms that all of us can understand and use. Most of what you said I knew but was amazed that I did not know it all until you said and showed what it all meant. Thankyou so much for a direct to the problem at hand and thoughtful presentation. John M.

Another excellent and articulate video. Clear and to the point with out being over technical. I wish I had access to this type of concise and accurate advice when I started getting into audio in the early 80s. I don’t have the luxury of a dedicated listening room. My hifi rig has to fight for it’s right to be in our family lounge. The lounge is far from ideal. 21 feet long, 18 feet wide and 7.5 high. It has plasterboard walls, a concrete ceiling separating it from the apartment above. A wood clad concrete floor, built on block and beam work as it is ground floor. One of the long walls is all windows from above 3 feet from the ground. It is ‘open plan’ so my 8 feet wide, 14 feet long kitchen, makes the room L-shaped! Ive absolutely no acoustic room treatment, other than a large, plush rug placed in front of and between my large floor standers. With much hard earned cash, time, experimentation, trial and error and powers of heated persuasion to get the long suffering wife on side, I have now built a premium quality rig, which despite room acoustic issues, does for the most part reproduce music the way I prefer to hear it. Over the years, I’ve upgraded components, cables, speakers Etc. Piece by piece and appreciated the sonic differences they’ve made, be it good or bad. However, I’ve recently made one change which has totally killed the ambiance of the room. I replaced our old leather 3 and 2 seater sofas for a slightly smaller, lighter 3 and 2 seater fabric sofas. Listening to music is now, well, far more intimate. My normal listening level is around 78db. I used to be able to achieve this by turning the volume control to 11 o’clock, I now have to turn it to 1 o’clock for the same results. I’m not sure that I’m happy with this new sonic intimacy. I guess I will learn to be happy with it as these sofas are here for the long hall. I have 2 subs, placed along the same horizontal line as my floor standers. I’ve now introduced a 3rd, down firing sub which I’ve placed centrally between my floor standers and in front of the opposite wall. I’ve had to experiment and reduce the intensity level on all 3 subs, but I have now achieved a more open and ambient reproduction. I have contemplated, costly professional room treatment, but I know that would push the wife to contemplate divorce, or murder. So it’s a case of minimising the compromises/concessions and maximising/appreciating the benefits/alternatives. Keep up the excellent videos Hans.

There's some real gems in here.. good stuff, thanks

All his videos are easily understandable. Very informative. So helpful.

Excellent tutorial ! Mes compliments cher Monsieur !

Thank u so much for this video! Your suggestions have made a huge difference in my monitoring station. It’s a small room but your work around has helped considerably! Thanks again!

Well structured and very very informative video. The most didactical and insightful that I've came across about stereo speaker placement.

Amazing tutorial. Thank you for sharing it!

Thank you Sir Beekhuyzen for the knowledge shared

Hans, I have been listening to 2 chl sound for a long time. Cardas has provided a placement table where data is entered (HxWxL) and a starting measurement is spit out. If room is rectangular move speakers 1/2" at a time (you can use one channel) until bass increases and then transitions to out of phase. I liked your floor crawl to find starting point. Since midrange and highs are in the signal correct phasing can be detected. With very small movements shift speakers to brightest sound while maintaining phase. I sit in listening chair moving toward and away from speaker listening for image to shift. If it does not that is almost your spot. Nudge speaker so sound "image moves behind the speaker. Measure distance to rear wall. Cut piece of pvc pipe and trim so it is a slip fit between rear wall & closest portion of speaker back. Using same distance from side wall position second speaker same distance to back wall. Give a listen seated as you would listen. Walk the center line to the back wall. Any movement of sound R to L indicates sound lobes along center line. Go through the procedure again. changing speaker to back wall distance. When properly set there is no lobing along the center line, The sound stage will be behind the speakers on a 3D stage and looking at each instrument will not shift its position. Takes a while but when you dial it in you will have an acoustic holograph and the speakers magically disappear. Hans technique with the mirrors on side wall indicate prime reflection. I make diffuser panels with odd lengths of wood glued to panels hung over those location. These panels can be painted, stained, whatever you like to make them blend in or stand out. You could make a wire frame with speaker grill cloth attached to the panels to visually hide them. I use 2x2 & 2x4 doug fir from 1.5" to 3.5" sliced to random lengths. Panel can get heavy so support well. Hans is the king so take his advice. I have had great success with my approach as well.

Het RU-vid algorithms heeft me een paar hitjes geserveerd. Dit filmpje alleen al is top 3 beste filmpjes ooit kwa hif. Tof ongelofelijk tof tof tof

I'm going to post the exact same response that was stated below, because it needs to be said again: This is the best and most informative video about speaker placement I have ever seen. Thank you!!!

I really like your explanations and descriptions. I also like the little comedic digs.

Thank you for the very informative video. Very well explained!!

Particularly good video. I have seen a similar set up called the "Master Set" here in Colorado, USA, which works very well. Also, I built a new house and constructed my listening room with dimensions in ratios of phi ᵩ (~1.618:1) to maximize spacing between standing waves. My room is approximately 3 meters high 5 meters wide and 8 meters long. I also have absorbers in the side first reflection points and a throw rug (with double carpet pad) on the floor to absorb the floor bounce. The sound is amazing, especially considering my relatively inexpensive equipment.

Best explanation of room acoustics I've seen

What a fantastic video. I am feeling happy that I could learn so much from this video. Thanks! And after watching your very honest biography and realising that you are a person with backbone, what used to be called integrity but is practically extinct nowadays, I gladly subscribe now to your channel. Thank you 🙏

Thank you sir! An excellent and informative video!

Great videos! Again Thank you.

fantastic explanation sir thanx for share ☺

Very informative ! Thank you so much . . .

The best explanation. Mr Hans thank you.

Heel duidelijk en helder Hans ++++

Thank you for this instructive video. Still valid, of course, after 10 years ! Amazing information there.

Dank je, Hans - very informative; subscribed!

Excellent Video. Thanks.

Excellent presentation. Really helpful. Thank you very much!

Great video, thanks Mr. Beekhuyzen

just finished watching. thanks new best friend.

this is the most intelligent video I've ever seen! thank you

good job man

Thank you

20:22 : "There are costly professional solutions, but they often lead to even more costly divorces." The quotes resonates with me, although in my case they lead to homelessness.

Good presentation Hans

Very practical concepts. Thank you for posting.

Thank you, Sir.

Tnx John

Brilliant explantation, I learnt loads thanks.

Absolutely the best video I’ve ever seen on the subject. Well done. Already subscribed…. 🙂

great info, bedankt.

Thank you for this educational video man!

Brilliant explanation

Your voice is so calming :-) Like the video!

Suprr useful info. Thanks Hans

Stellar job, Sir!

Very interesting theory's on acoustic solutions and I did like the video i have seen and listened to so many people's ideas and solutions to this the room set p it's hard to know what's right what's wrong, and yours to offered some good ideas but still it seems are vague, so I shall continue on my quest for creating the perfect listening area and environment , but thanks for sharing your eloquent thoughts and solutions , best wishes Steve Henderson, Grooveline recorders UK,

Fantastic video and channel. Thank you!

Well explained! keep it coming

fantastic explanation!

great explanation. you should do a video only for sub woofers placement.

I recently began work to create a home studio and have been trawling the web to better educate myself on acoustics etc. Your videos are exceptional, I'm surprised to find myself digesting such 'abstract' technical/mathematical information on the first play-through. I'd only request that you do more 'general' educational videos on the science of sound, such as this one... Your pace and clarity in writing and presenting makes light work of these very demanding subjects, a rare thing. If a specific suggestion is more useful... A video going into more detail on sound absorption and reflection techniques perhaps? ...You touch on the subject here, I'd like to hear more on those improvised methods from the 80's. :-) Subbed and shared ...and thanks.

very nice audio. some talk about audio BUT their video has horrible audio well done

Hello Hans. I’m impressed by the audio knowledge you possess! Also, your English is very good! Friendly regards, Emiel (I’m also Dutch).

Fantastisch gedaan Hans! Groeten, Johan Fransen. :) subscribed!

You drop some good zingers in there for those listening closely :) BTW the video was very helpful. Thanks.

Wow, I'm speechless.

One of the simple and easy understanding video. Most of the cases,all talking about BOX room,which means it has symmetrical side walls but here in our city,most of us having a living room like 14 feet wide and deep 12 feet,one side window,one side to dinning room most of audiophiles here can only place the speakers on the 14 feet side. Do you have any suggestion in acoustic treatment in this type of room ? Thank you in advance as I'm going to move into a new home with 23 ft wide and 15 ft deep and have no choice but to put speakers on the 23 ft side (the rear wall of speakers only has 13 ft).

Excellent RU-vid Hans! Last year I moved my music audio system down from our 13' x 24' living room to a 24' x26' (plus alcove) "man cave", while upgrading most of the equipment, including a new set of speakers. I got the speakers really "dialed in" to the room, sounded just great....until I added a pair of sub woofers. The resonances of this "man cave" were such that bass sounds lacked all "definition". With the help of the Room EQ Wizard software and a calibration microphone, I was able to combine the addition of bass traps with repositioning of the speakers and sub woofers, to dramatically improve not only the low bass sounds, but the mids and highs, and the stereo "sound stage". Maybe in a future RU-vid you could provide guidance on the tuning of sub woofers and rooms!

thanks for your great advice .... best channel ever !!!!

Excellent presentation, Hans. As a physicist with acoustics specialisation and a lifelong Hi-Fi nut, I know you offer very "sound" advice! :-) All the best, Rob from Switzerland

thank you!

Very good!

You can find reflection points by yourself from your listening position by facing backwards and using the mirror! Saves getting your better half involved!

Hallo Hans, uw uitleg is (zoals bij elke video) uitgebreid. En ikzelf kan erg genieten van de grapjes die u er in borduurt. Ga zo door!

So informative

Thank you Santa :)

so good
