MAKE POINT-SOURCE SPEAKERS (CHEAP AND EASY)

TRY IT YOURSELF, PUT IT ON YOU TUBE AND LET ME KNOW. TO HAVE A PHASE-ALIGNED, POINT-SOURCE SPEAKER (LIKE A FULL-RANGE) BUT GOES UP TO ABOVE-HUMAN-HEARING IS THE HOLY GRAIL OF SPEAKERS. SHOWN TO BE DONE SO CHEAPLY AND EASILY! THESE ARE THE BEST SPEAKERS I’VE EVER HEARD AND YET THEY COST NEARLY NOTHING. BUT YOU DO NEED EXPERIENCE IN CROSS-OVER DESIGN AS WELL. WITH CROSS-OVERS, I THINK, KEEP IT AS-SIMPLE-AS-POSSIBLE (WHILE STILL GETTING THE BEST SOUND). THE SPEAKERS ARE GOOD ON REALLY LOW VOLUMES (GOOD TRANSIENT RESPONSE), REALLY GREAT AT REALLY HIGH VOLUMES (PIEZOs HANDLE BULK POWER AND MED-RANGE IS DRIVEN LESS BECAUSE OF WOOFER). TOTALLY PHASE ALIGNED MED AND TREBLE THAT GOES UP ABOVE HUMAN HEARING! FULL-RANGE SPEAKERS NORMALLY DON’T QUITE GO UP TO HUMAN HEARING FREQUENCY. BUT THEY ARE PHASE-ALIGNED AND SO ARE POPULAR. HARDLY ANYTHING COMES OUT OF PIEZOs BECAUSE MOST OF IT IS ABOVE AUDIBLE LIMIT. BUT WHEN YOU PUT IT IN A FULL-RANGE SPEAKER CORE, THE SOUND IS STUNNING. IF YOU HAVE THE PIEZO ON ONE SIDE OF SPEAKER, THE SOUND IS WHIZZY BECAUSE IT IS NOT PHASE-ALIGNED. I EXPERIMENTED BY MOVING THE PIEZO IN AND OUT OF CORE. YOU CAN TELL THE DIFFERENCE WHEN YOU PUT IT IN THE CORE AND THE SOUND POPS OUT AT YOU (STEREO IMAGE IMPROVES, TEN-FOLD)! TRY IT. YOU HAVE TO BE LUCKY ENOUGH TO GET FULL-RANGE SPEAKERS WITH A HOLE IN THE CORE (FOR THE WIRES). HERE IS A REALLY EASY WAY TO DO IT. JUST GET PIEZO DISCS,AS SHOWN IN VIDEO (WITH THE WIRES) FROM OLD GHETTO-BLASTER AND PUT WIRES …
