I wish Joe and Erin were my next door neighbors. I could wash their cars and they could DSP my home theater.❤❤

[@peanutbutterjellyjam2179]

Yes, but they'd only need to DSP your home-theatre once.

The room killer 😂

When we will see magic beans? Will it work with anthem?

[@joentell]

From what I've seen, Anthem is very limited in what it allows you to do manually.

How bout denon 3800h with Dirac ?

[@leonnoel1243]

Just want to congratulate you on magic beans and the disc. I have monitor audio silver 300 and I feel there a little sharp. Is that because I have a very untreated room?? Can that be solved with treatment and magic beans????

[@joentell]

Thank you! It could be a bit of both. Have your seen the frequency response of your particular speakers? Another thing to look at is the directivity index. Depending on those things, it will help you understand if the speaker will take well to EQ like Magic Beans.

[@daleboylen6427]

Erin's method is the better of the two. if the speaker is properly designed (BIG IF), the ROOM is causing issues, especially in low frequencies, as the average living room is simply not designed to reproduce deep bass (something to do with wave lenghts and physics, which Joe doesn't believe in). The room will cause both peaks and cancellations, as Erin correctly pointed out. While you can "tame" peaks with EQ, there is nothing you can do about cancellations with EQ, Joe. If it's not there, it's not there. Now, are you sure what you're hearing is a room node and not low frequency phase shift? Room "Correction" doesn't work. Room TREATMENT does a much better job. Then you eliminate the added time delays caused by the DSP eq, having one more piece of electronics in the signal path. Of course, people today don't want to do room treatment. Takes time. DSP is easy. I have to remember this generation invented instant rice because minute rice took too long. I know a recording studio owner who EQ'd his vocal booth using an I-phone app. SMH. A PROPERLY designed speaker should never sound "Chesty" in the voice range, Joe. I know, I'm wrong, you are right. I haven't changed anything in my system since 2004 other than DAC, and you seem to be the one never happy, constantly messing around with DSP trying to find the "Magic beans" to take the place of engineering. You remind me a bit of that dude in Canada, Jay, who bragged about owning over 70 pair of speakers before becoming an audio reviewer. What's the definition of insanity again? Before upgrading speakers, you may just want to look at upstream components, as all a better speaker can possibly do is more clearly reveal the fault of those components. No speaker, no matter who makes it, can IMPROVE on the signal it is being sent. Magic beans or no magic beans. Stop with the gimmicks and put some research into your systems is my advice. If you like the nonsense from Joe here, you'll LOVE Randy's channel at Cheapaudioman. By all means do NOT listen to guys that know what they are talking about. This is "Fun fi" and where's the fun in learning from them? Far better to piss money away on say a Wiim amp with a puny 48 volt power supply, a TI 3255 IC chip output, lacking the current needed to PROPERLY play music, that doesn't play well with high impedance speakers (many of which go VERY high) and has a rising frequency response in the top end, then blame it on the speakers and use the built in 10 band EQ to "Fix" the poorly designed amplifier. You could also use cables as tone controls if you have a LOT of money to piss away.

Ok, Mr. "Room Nodes." Look that up and tell me if that's the correct term. It shows you've never read anything about it or you would know better. You've only heard it which is why you don't know the correct spelling. Maybe this might help: kzbin.info/www/bejne/gobYqpKnrqmmnposi=PkuiowfFHAlNSORl

@@joentell For fucks sake Joe. You're STILL trying to win an audio argument with me? It is not possible that you can win this. You couldn't prove my math wrong,, so now you've resorted to spell check. And send me another of your videos to watch On Dolby nodes? I'm starting to think this is more of a status thing to you than a knowledge thing.

[@daleboylen6427]

@@joentell I mention room nodes, IE standing waves, and you send me dolby nodes? Dolby is an encode/decode noise reduction. Im talking about standing waves, which you can calculate by multiplying your room dimensions by either 4 or 2. Divide those into the speed of sound (1130 feet per second) to get room NODES. When a second room dimension is added it's bad news when it's resonance frequency coincides with any other dimensions. It assumes the speakers are flush against a wall. If your room absorbs at 125hz say, you may NOT get a standing wave even though the math says you should. Sudden boundary changes, like an L-shaped room or a ceiling that jogs up reflect sound as if they were a real boundary This is because the acoustic impedance changes instantly--the sound pressure is suddenly free to expand. Sheer waves are not normally discussed in acoustic books because they are less loud, but never the less audible. The math can be found for this in Lord Rayleigh's "The Theory of Sound" book published in 1877. The frequency ranges of diffusion are necessary and determined by the size of the room and the materials in it, Measuring the actual reverberation time in any room at each frequency requires sophisticated instruments. To start, you MUST find out the coefficient of absorption" specs in EACH material, in EACH frequency range. See, it's as simple as "Early reflections" right? I actually have about 6 pages on this topic,. I'm probably NOT your typical KZbin commenter....perhaps you've figured this out. As far back as the early 1980's, Yamaha called me for advice on how to improve their amplifiers. I was happy to advise. A major issue with those 70's and 80's Japanese amps (Not just Yamaha though they were the biggest abuser) was their massive overuse of global negative feedback. Lowers THD but creates transient distortions such as TIM, or Transient Inter- modulation Distortion, which is far more offensive, as is anything to do with phase errors. Nelson Pass had to correct the opposite problem from early Adcom amps like the GFA1 which blew themselves up do to instability issues. He did a fine job on the 535, 545, 555 series. I digress. Hope my info on room standing waves (Nodes) helps.

@@daleboylen6427 it's room Modes, not Nodes. You're welcome.

[@daleboylen6427]

@@joentell kzbin.info/www/bejne/h5iWqWVtjp1mrZI A bit technical, but this video explains why trying to "Fix" phase or time issues in speakers is a nightmare. This video is ONLY for sub frequencies. We had to do all the math for EVERY frequency in a full range time and phase aligned system. In a nutshell, so many things can alter what you think you're seeing on a scope. Crossover induced phase shifts are even more difficult to get right. A simple 1st order unit is required. You cannot fix a 2nd order crossover. You can make a 4th order unit phase coherent, but not time coherent. Put simply, the drivers do not start or stop at the same time. I suggest you watch this video and understand it as it will help you in your endeavors. The math for this is QUITE complex which is why it took us 30 years to crack it and perfect it. I'm NOT going to argue with you again as that is a waste of my time. I'm trying to HELP you understand this better. Hope this helps.
