A compact, sub-bass loudspeaker designed to provide 
high SPL extended bass to Adamson SpekTrix enclosures, 
the SpekTrix Sub is equipped with two powerful AW18

The cabinet is fully braced to minimize LF resonance and 
maximize efficiency. Four sets of captured, precision-
machined aluminum rigging hardware are spring-loaded 
and retract into the cabinet body when not in use; and 
four NL8 connectors (two front, two back) enable easy 
cable loop-thru regardless of the sub’s orientation.
