Is this the correct way to find the driver diameter? I don't know anything about prospective geometry.
>>1545731Yeah, that works. Another way is just to use the fact that the box is about 18.5", then measure a line across the front of the box, and what percentage of that is speaker. I used a graphics program where I could set the scale for the ruler, measured across the box at centre of speaker height, adjusted the scale until it read 18.5" then measured the woofer diameter at the same height. Any of those ways it's about 14" for the woofer.
>>1545731Forgot, on speakers it's normal to say cone diameter not driver which is mainly for headphones.
