3.2.2 Selecting the crosso er frequency
For opera ion wi h an ex ernal crossover ne work such as our BEHRINGER SUPER-X PRO CX2310, please
refer o chap er 6 SPECIFICATIONS for recommended crossover frequencies. We recommend using a slope
of a leas 12 dBhigher values will improve performance. A slope of 24 dB is ideal.
3.3 ACTIVE (BI-AMPING)/PASSIVE subwoofer operation
EUROLIVE SERIES subwoofers also fea ure an in egra ed crossover. Driven in passive mode, he B1500X

+To ensure optimal performance in combination with the B1020, the polarity of the B1500X
subwoofer has been re ersed (180°) in the factory. For operation with any other EUROLIVE
multi-way enclosure, the loudspeaker polarity must be re ersed by qualified ser ice personnel.
We designed he B1800X as he perfec subwoofer for he EUROLIVE mul i-way enclosures B1220 and B1520.
Of course, he B1800X can also be opera ed ei her in passive or ac ive mode.
