EXTENDING RANGE WITH PASSIVE SUBWOOFER
The passive system’s frequency range can be extended to lower frequencies adding a LAs418 (2x4ohm).
In that case, the LAs15’s
High-Pass Filter must be changed to 60Hz - 24dB/oct Linkwitz-Riley.
Connect the LAs418 (2x4ohm) using a NL4 connector with 4 conductors cable.
Match the Low-Pass Filter of the LAs418 with the LAs15’s High-Pass Filter.
Any of the N-RAK models can be used to power the extending range subwoofers.
HYBRID SYSTEM
The hybrid consists on Active subwoofers (LAs15A) powering the passive LA26. Each LAs15A is capable of
power up to 3 x LA26 cabinets. For increased headroom use 1:2 sub to top ratio.
