Hi Wayne,I've also been studying the information on the 10PI on your website. Comparing the dimensions of the 4PI and 10PI, it seem like the 10PI is just a 4PI with the woofer facing the other way and fitted with a horn. Can you confirm if this is true?
Have you, or any of your customers ever try convert a 4PI into a 10PI, provided tweeter attenuation is adjusted?
