Even though I knew it worked, I've always wondered "why" diffusion worked. I've always heard explanations like, "it breaks up the sound" or "it traps the wave" or other things that didn't really tell me anything. Your explanation that it changes the sound enough, that it isn't correlated by your brain as the same as the "direct" sound from the driver, makes perfect sense. Thanks Paul!
And 80 miles north(ish) of Tunisia. Very nice people with lot's of history and a great love for music! Actually, most of their old houses have really thick limestone walls... I wonder how sound waves would interact with that material?
Had a port visit in Malta and Palma in the Navy, loved it. Malta reminded me of a background in an Indiana Jones movie, everything was a light yellowish sandstone....beautiful.
Yeah, and the home of Knights hospitaller after Crusade wars and many adjoined Templars after their end. Thus maltesian cross which also was a signum of Teutonic knights - the founder of Brandenburg and Prussia - to this day to German army.
Malta and acoustics. Check out the hypogeum. Its an underground "city" carved from the bedrock, very ancient and very mysterious. Specifically it has some bizarre acoustic properties. There is one chamber, somewhere in the middle of this vast subterranean network, where one sitting inside, speaking at normal volume can be heard perfectly, as if by broadcast, anywhere in the complex. I reckon being an acoustics guy with an interest in Malta, this little nugget is right up your alley.
I'm half Maltese on my mother's side of the family, spent time on the island when I was posted to Cyprus while serving in the RAF back in the mid 90s, lovely islands and very friendly people on both islands,
Really good explanation, Paul. I read almost 500 pages of Floyd Toole’s book ‘Sound Reproduction’ and you summarized and demonstrated the biggest room issue, first reflections, very well -your ‘talking and walking’ was brilliant. And you didn’t ask us to interpret even the first graph! (An inside joke for those who are familiar with Toole’s work.)
But Paul doesn't have enough diffusion in the front wall. So, the sound field is going to be a combination of diffused sound and reflection and it's not going to be a REAL diffused sound field. He should have at LEAST 50% surface coverage first. But there are other things you need to do first before you add diffusion.
When I placed a GIK diffuser/absorber panel within my listening room, I really didn't like it for the first couple of weeks (obviously wasn't used to it) but I'm so glad I persevered because now I couldn't live without it!
The simple answer to this is, that when No diffussers is in ude, the listener will have a hard time processing the sound coming towards you. So absorb materiale for corners and sides, can handle low freq. But for the out of time critical mids and highs, you need some difussers to scather the Sound! It can change your HI-FI to new highs, i promise you ✌️♥️🇩🇰
excellent information, i didnt know you should deaden the rear wall, thanks paul, ive also heard u should use asborbers or high freq, and diffusers for low range
These are not traditional box speakers, only bass section. They are like closed box magnetic ribbons from 300 hz up (?) therefor more similar to Apogee´s without rear radiation... Magnepan, Martin Logan, Apogee, etc are much less sensitive to a normal acoustical treated room (read 99% of all rooms out there) because of their narrow dispersion pattern, which is a good thing IMO. I am a planar guy and can´t go back...
Once i read that you will get a great stereo image from 2 speakers placed in anechoic chamber Because we hear a wall when it reflects the sound For instance a bat would keep crashing against the walls in anechoic chamber And conversely the worst room for Soundstage would be a reverberating one
If your room is plagued with reflections, you will want a degree of absorption. Not so much to make it dead. But enough so that it is no longer an echo chamber. I put absorption panels in an alcove to the side of my living room. Any sound that managed to travel there and make it back to me cannot be good. I want nothing back from that alcove. For the rest of my listening room, I have a combination of absorption and diffusion. Did I get it right? Maybe not. It is really hard to know which panels to buy for each wall and the ceiling. But my results are really good. My music sounds much better. But a different arrangement of my panels would probably yield even better results. I'll never know. There are companies that specialize in this, and cost a fortune. If you have the $$, then go for it. But you will never really know if that company got it entirely right, because you will hear only their final set-up, and it will sound much better. But how could you ever know if they could have done an even better job? My room treatment are by Vicoustic. Their panels work. But they sell expired glue, their panels come down, and their warranty is 99% useless. It took them 2 years to resolve my issues (that's 2 years with 1/3 of my panels eventually coming down). Imagine living with that sight in your livingroom. And it was one of their installers that did the job. The problem was with the expired glue. And guess what, they shipped more expired glue when, 2 years later, they honored my warranty. This time, the installer went to my local Home Depot and purchased some other glue, and it has been at least 2 years and no panels have come down. By the way, there are other ways to tame the sound in your listening room, such as with plants and curtains and carpeting, etc. Cheers!
Malta has a culture dating back thousands of years. But Americans dont know that. Also conventional speaker systems can never beat the immediacy, speed, impact, dynamism, slam and realism of properly engineered horn speakers with compression drivers and horn loaded bass enclosures. eg Klipschorn heritage line, Aries Cerat, OAM and Western Electric and RCA vintage horn speakers. They can also play loud and soft.

Hi Paul how is the FR-30 better then the IRV as far as i can see the designer must of work for a dress design and I bet that stuffing a lot of drivers in a designer box can make any speaker sound great.. besides watt to sensitivity I say you can get more performance out of the infinities. Again back to the design. I think you.Copy the box design of Bang & Olufsen Beolab 50 and added more legs. I don’t think Art Would be happy with the change in direction you took after his death. Please comment or reply back when you got the time. Thank you Sir.
I saw that 1st reflection is no problem if it is 5 microsec delay which means 1,7m longer path. If it isn't, then it shoild be diffused. On Hans Beekhuysens' channel. Can you comment this?
My plans for inclusion into the PS Audio family grows stronger but I am lacking Imperial credits for the FR30’s at the moment. From my research, this is the way!
Great video Paul, I had a further question with regards to the sound reflections from the side walls. Are these reflections what gives me the illusion of the sound stage being wider (to the left and right) than my actual speaker location. I know how the sound stage is generated between the speakers as you have explained this in another video of yours, but I always wondered about the sounds that come from outside the speaker placement, is it reflections from the wall or is this illusion direct sound from the speaker cones?
Diffusers. You want diffusion at primary reflection points, and absorption at the room nodes. Search for Room Schroeder Frequency. Below this frequency, sound waves pressurize the room, above it they bounce around. Any wave that reflects and reaches your ears in less than 4 to 8 milliseconds (depending on your sensitivity) of the main wave will be interpreted as being the same wave and results in muddy sound without clarity. Floors are usually the worst offenders - hardwood floors sound really terrible and can be addressed with a throw rug. Backwalls are usually the next worst since the sound comes from behind and confuses the brain.
I hope the FR30s punch above their price point. But they won’t be considered “world class” speakers, because the tweeters are too high. Tweeters should be at the listeners’ ear level. I also don’t love the crossover points.
They do punch above their price point. Don't knock them if you don't have a pair.The tweeters are perfectly placed below the mid-range. you're assuming your height, type of chair and sitting position is everyone's sitting position but hey,make your own world Class design, we'll support you if it's any good.
I’d love to complicate this matter a bit. These speakers are desktop speakers. They dominate my area of frontal audio area of focus. Another factor here is, I have a monitor in front of me. I’ve purchased 4 (12x12) pvc diffusers. I plan to apply two of them on the inner desktop speaker panels. With a near-field perspective, can these panels help my sound? Unfortunately, I have to wait two weeks or so.
Some day in the far future, we will bypass the ear completely and tap directly into our auditory nerves. That would eliminate everything in the way of absolute sonic clarity from 0 to 50KHz with no compromise. Until then, we're stuck with unlimited half measures and compromises. Do as we might, nothing will ever sound quite right due to the physical limitations of everything we use - source, amplification, vibrating speakers, the air itself, the room, our ears, etc.. Only once we've bypassed all of that will we get perfect sound.
@@mateodeo9161 He's not talking about hearing in the natural sense.. haha he's talking about jacking into the auditory nerves bypassing the outer parts of the ear entirely.. who knows what our brain can perceive as auditory information once we jack directly into our brains.. granted, it will probably twist our minds..

Does diffusion directly behind speakers make sense? Why would either diffusion or absorption directly behind speakers that are positioned too close to the front wall not create a sense of the speakers being a few feet further away from the front wall? Please advise.
In my project recording studio I use both absorption and diffusion behind my monitors. In this case, the corners are treated with floor to celling absorption to mitigate bass build up. Bass frequencies are notorious for building up in corners. Directly behind the monitors are diffusion panels.
@@mateodeo9161 So you ignore the amount of reflection on other walls compare to the direct sound. For me, I don't stick my speaker to the side and front to the wall as much as possible. A walk around the speaker is a good distance. Triangle relationship is the most important.
could anyone give me answer for cone shape an pattern of the sound wave formed, ect does a flat cone have a different sound wave then concave cone or square vs triangle shape?
The driver cone shape does have an effect at higher frequencies. The the directivity of a driver will always vary with frequency, and is affected by both the cone shape & size, and the shape of the baffle that the driver is mounted on. Take for example a 3" dome midrange vs. a 3" cone midrange. Both might have similar directivity below 1kHz, but the dome will have wider dispersion above 1kHz.
@@TheMirolab thanks, that's where i was going with that is dispersion characteristics , do you know of any real tests done on this stuff, i would love to learn more, i cant find much research on this tho , but someone must have done it because most all cones are shaped the same , just always wondered why, i see flat cones work just as well an can have better off axis response, so just got me thinking
I just can't get on with the idea of multiple 8in woofers.. None of them can handle 110dB of raw 40Hz bass tones. That's why Focal use a 15in Evo driver in their Utopian loudspeakers.. 15in drivers deliver much low extention and greater power handling than 8in drivers.
@@coreyfreeman6226 If your spending $30k you want a speaker to be able to play at concert volumes. The AR30 won't do that. It not a matter of listening at that level but a case of power handling capabilities.

OK, I get it, but what about headphone (earbud) users? Talk about acoustically dead! Be like both of your floor speakers pressed right up against your listening chair aimed right at your head. I've tried that and it sounds awesome. Like wearing 100Lb headphones! LOL.

Malta is beautiful, but the food is really bad..Old English colony , so they took the bad English food . I hoped to have really nice food there, because it's in The Mediterranean Soyou think the food should be something like Italy, Greece or Spain. It wasn't
Malta is lately well-known as a global tax haven, where corporations park billions in profits to avoid paying taxes in the countries where they do business. You will likely find lots of mega yachts there....
Lol, your brain doesn’t ignore diffused sound. The brain interprets it as “airy” or “spacious” sound. You should have done some basic psychoacoustic research.
Your knowledge combined with your personality make this channel very watchable.
