The H series is a passive line
array system, that there are several models for you to choose. Some new
techniques and several patents are being used in this series. Such as the mid-high coaxial expanding technology adopted by the LA-24 and LA-30
which ensure the mid and high frequency synchronously produce equal SPL; the small
angle HF horn; the phase adjusting component applied in the LA-20 which make
the sound clearer, eliminating the bad sound performance. They can be used in many
indoor and outdoor places like the big/small gymnasium, playground, mid/big
auditorium, multifunction room, mid/high class H room and all kinds of big show,
etc. Also there is LA-12S and LA-16S as the subwoofer to combine use with the
LA-12 and LA-16 to form a high power line array system.
