Introduction
The D.A.S. Sub-118 is a bass-reflex subwoofer system for use in active systems
where bass reinforcement is required.
Applications
The Sub-118 is designed for subwoofer
reinforcement applications in clubs and
small to medium sized venues.
Description
The Sub-118 houses a D.A.S. P-18 18" cone
transducer configured as a direct radiator.
This driver features a 3" coil and carefully
engineered cooling scheme, resulting in high
power handling and low power
compression.

As with any bass unit, the Sub-118’s low
frequency output will benefit from placement
against walls and/or floors.
The top panel contains a standard 35 mm
diameter pole mount socket for use with
metal posts for mounting full-range D.A.S.
systems to the SUB-118 sub-woofer unit.

FEATURES
The compact enclosure is manufactured
from MDF and is finished with a hard
wearing catalyzed polyurethane paint that
permits color adaptations and provides
weather resistance. Loudspeaker
components are protected by a heavy-duty
steel grille sealed against corrosion using a
poliamide powder coat finish.

R
Corresponds to the AES power handling rating for the component, based on a 2 hour test using a 6 dB crest factor bandlimited pink noise
signal.
P Conventionally 3 dB higher than the RMS measure, although this already utilizes a program signal.
K Corresponds to the signal crests for the test described inR.
F As per IEC 268-5 (1989), re. a one octave band centred at 2000 Hz. Half space anechoic.
I In practice cable and connector impedance has to be added to all impedance values.
S For the 125 Hz one octave band.
B Average of one-third octave band measures.
One and one-third octave bands comply to ANSI S1.11-1986.

NOTES. 1.Frequency response: referred to 1 m; low end
obtained through the use of near field techniques; one-third
octave smoothed for correlation with human hearing. 2.In
practice, cable and connector impedance need to be added.
3.Low frequency near-field techniques used. 4.Directivity
characteristics plotted with respect to frequency are the
average within the one-third octave bands of center
frequencies noted by the marks at the bottom of the graphs,
but are joined up for display purposes. Interpolation was
used below 100 Hz. All other characteristics plotted vs.
frequency use 1/24th octave resolution. Regions of less than
1 dB below goal level and sharp notches may be ignored
when calculating beamwidths. 5.Directivity factor and index
were computed from two degree resolution vertical and
horizontal polars using sinusoidal weighting. 6.Polars were
acquired by placing the unit on a computer controlled
turntable inside our anechoic chamber. Measurement
distance was 4 m.
