Just to be factual, these are not Mark Porzilis personal pair, Mark never had a personal pair of Pipedreams, the only ones he used for a period of time were a pair that a friend owns currently and they were a protoype, never built for resale, more of an experiment, one that went very well!
I love line arrays, but they need a big room and lots of room behind them to work well....at least these guys do...
