@DocLow Low frequencies work best since the speaker cones move less and less at higher frequencies. I shot this video with the amp maxed out to achieve the greatest image size over a short projection distance, resulting in some distortion in the speakers and camera mic. As an alternative, one could use a lens to magnify (I often use one side of a pair of binoculars turned backward) or project over a greater distance (not a problem for a laser).
Woah! Ingenious!

Jaja. Really nice. Really interesting, even if the result is less than perfect. Congrats.

Really cool dude; ingenious. Speakers used as servomotor drivers positioning a Laser, 5/5
