#EigenFunctions - Twitter Hashtag

3 days ago

Ordinary #loudspeaker cabinets are basically cuboids. Along the XYZ axes, they present rigid walls that require #acoustic #eigenfunctions to have zero displacement at the walls. This severely limits their resonant spectrum. With the Inverted Projected #Tesseract loudspeaker, the inner cube is bounded not by six walls, but by six pyramidal ducts. These provide boundaries that reflect the sound at #displacement #antinodes -- producing, at frequencies below 1KHz, a pulsating cube inside the cabinet that cooperates with the woofer located on one of its faces. Lowered distortion...and omnidirectionality. https://t.co/KKgW2Jdpoi

@glowing_finger_ @iH0DL @rarible @_theperfesser @WizardX_0x @xCryptochild @metamick14 has it reduced to a math formula i'm sure he'll get sum super-genius like @katchwreck onboard and break it down to #Eigenfunctions soon. my formula: if i can buy & 2x, i'll buy again, thats it.
