I got no X-30 with my Servo and when reading through the post on here....some poeple got it and some never. It seems if you want the X-30, you will have to pay an extra £100. NOT SO............ I went back to RS a couple of days after getting my servo and said. " Hello i brought a servo 15 the other day, but got no controller for it" RS Say " OH.....i told him to order one with it...we will sort it out" So a week or so later i now have an X-30 crossover....i was talking to the guys at RS and apparently, the X-30 is included in the price of the Servo15, but when they order the sub they have to place an order for a X-30 at the same time. They do sell them for £100 if you want it as a seperate order, but because the other paradigums come with all the controls on them and the Servo has just the one.....then RS are nice enough to give you a X-30 to have control of it. It's just that, because the people that work in these shops dont have the experiance or knoledge of the Servo, most of them forget to order it with the servo. So all those people on here that brought a servo and never got there controller.....go back and see if you can get it. While i was there i was ganner order a PW2200, just for the fun of it and because of the price £260....but they have no more in the warehouse.....just a few scattered around the country on display in shops. He asked why dont i just buy another Servo.....i said, you aint got anymore left.....he checked on his computer and said....yes we have....its showing 30.....but when he looked more in to it, they were returned/repair jobs.......so i never bothered. I like the Double shielded coax lead, they put in with the X-30.....that will come in useful.
