I expect to buy two LE15A BLUE SERIE , the salesman tell me that the blue series is a series edition special with more dynamics and more rapid better magnets, and better measurements. the membrane is yellow, the first was rigid, the second was more flexible. the 15A is best the 38 from JBL and the 38 which descend it + low from all the marks ,
What is thrue ? is it a good deal? The price is 730 $.
