is the D A S recommended

subwoofer unit to be used along AERO-38A when subwoofers have to be ground stacked. When subwoofers
be flown,

is the D A S recommended subwoofer.

Note: Due to the frequency overlap in the region between 60Hz and 80Hz, an external processor

(DSP-1Sub) will always be necessary in order to add the necessary delay so the phases of the AERO-38A and the
subwoofers match.

All self powered units incorporate the necessary

signal treatment in the amplifier, including cut off frequencies, limiters settings, etc.!!
