FACTS ABOUT DLS Iridium 1i TWEETER
Using active crossover to the midbass driver.
If you want to run the midbass driver with active
crossover, not using the passive filter box, you must
disconnect the midbass driver filter circuitry. This is
done by moving the woofer jumper to OFF-position.

RECESSED MOUNTING 2:
Sometimes it´s necessary to install the tweeter at places where you cant
use the round flange. The flange (A) is possible to remove from the tweeter
element (B) by turning it CCW.
If you prefer to install the tweeter with the flange attached to the tweeter
element, we recommend you to add a string of strong glue on the bottom
side, between flange and chamber, to secure it. This gives you the best
sound reproduction in this installation.
