Column Array Systems * Discussing the GOOD and the BAD

We are discussing a very passionate topic. Our loud speaker systems. In particular, the very popular Column Array Systems. They are not for every application and you should know where they shine and where they come up short.
My guests are the founder of " Harvest of Sound" DJ workshop, Lou Paris. And show regular and audio genius Tony Fernandez! 
These guys know their stuff so if you have or want to get into column array speakers this program is a must listen!
