A controversial takes on low cost speakers with a lesson...

asvjerry is awesome

If you don't have the bass right you've got nothing. Everthing else is secondary.

This can easily be put to the test.  Disconnect your left & right two way speakers but leave your sub hooked up and listen to a track you like and then do vice versa (unhook sub and leave the two ways connected).  Personally, I would prefer the second option.

For physical acoustics:

Any presence of a phantom speaker   phantom Speaker a +speaker A  and speaker B + phantom speaker b is the result of distortion caused by "speaker boundary interference effect" as well explained by my first acoustician video...

 

 

For psycho-acoustics:

We have 2 ears : then the speaker A will create by time delay for each ear a phantom speaker image a and the same for speaker B and his image b for the  other ear...

 

 

Then the phantom image of speakers is not only the result of acoustical physical conditions but result in a stereo system by the way each ears will perceive each speakers with a time delay...

 

These facts illustrate how complex is small room acoustics and i used these facts with great result  creating  an holographical surround space with my stereo system...

 

In a word distortion is not a simple negative physical fact resulting from boundary interference effect but result  also of our body organization (2 Ears) perceiving unnaturally the same sound from 2 sources (stereo system) ...

We must not simply  eliminate distortion then  , we must  learn how to control it in our system/room.... 

 

 It is not enough to understand physical acoustics, we must understand basic psycho-acoustics and learn how to use it...

 This is why the balance ratio between LEV and ASW, between listener envelopment parameters and source width parameters  ask for more knowledge (reflections controls and pressure zones distribution controls)   than  just basic physical acoustics about speakers placement  as illustrated by my first acoustician video...

 

 

 

 

 

 

There is a better road than the mechanical tuning of a room with a grid of Helmholtz resonators as i did for sure ( not esthethical and not suited for a living room )...

The methods used by Dr. Edgar Choueiri  will be more efficient using basic psycho-acoustic laws to compensate  for the fundamental flaws of any stereo system if your room is minimally under acoustics  control ( the right balance between absorption/reflection/diffusion)...

 

Those interested by acoustics with stereo system must read his articles...

Those interested by acoustics experiments must read about sound waves  reflection controls lateral and back reflection powerful impact  and pressure zone distribution control with Helmholtz resonators...

 

Upgrading may be useless  if you ignore acoustics....

 

 

 

 

 

@uncledemp ...and I'll thank you and @gano for the kindness.
Like many, my abuse muse gets in the way, and I recoil into my inner lizard and prep for Deaf Comm 3.....well, perhaps not many, but I don't want to come off as just another softcore troll with no axe to grind upon anyone....no.

"Damn, a troll I may seen to be...but I'll strive to be an interesting 'read', perhaps a *L*
....maybe a "...yeah, close 'nuff....to be...'interpreted' ...😏.."

Been a weakend...low energy, slo-mo physically, got a r hip and knee that just as it started, I got dropped from my PHP after the RNA quit the place to return to an ER...  Can't blame her, old humans have to be boring with their SOS...
Just before or on too close to not be curious about 'timing' and how it can be...
?🤷‍♂️🤨😒...
Occurs just about the time I'd visited the DropThruClinic for them to Xray my case of hurt.

Had to call a week later to find out wth was up....got the Xtech I'd gotten pic'd by.
"So, what's up, what did you see or not"
"Only thing that I noticed was a crack in one of the bones.  Couldn't tell if it was old or new...."

                                                           oh

"Can I view the pics?"

"They've been sent to our file storage along with the rest of your file.  I guess you ought to call them."

New PHP appt. 9/9, but least its' this year.

Politics?  AVL demo, chill, happy, Friendly, I've never as many smiles anywhere else in this life, even at family gathers....

The phoney cop didn't.....

Enough if only for awhile....

For my upcoming B'Day, a gift I will wish for us all, if only here, is a space we
enjoy whatever rakes your yard as good or as good enough *4now*.

...anyway...see y'all on the screens, J
