Sub-118 Dynamics TFSJFT 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. Direct radiator sub-woofer 18" low frequency speaker 400 W power handling Rugged steel grille SPECIFICATIONS RMS (Average) Power HandlingR: Program Power HandlingP: Peak Power HandlingK: On-axis Frequency RangeF: Usable Frequency Range: Nominal Impedance: Minimum ImpedanceI: On-axis Sensitivity 1W / 1 mS: Rated Peak SPL at Full Power: Nominal -6 dB BeamwidthsB: (100 Hz octave) Enclosure Material: Finish: Transducers/Replacement Parts: Connector: Dimensions (H x W x D): Weight: 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. ® SOUND PRODUCTS WARNING!

Loudspeaker components are protected by a heavy-duty steel grille sealed against corrosion using a poliamide powder coat finish. ALL DIMENSIONS IN MILIMETERS 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. 110 Sub-118 FIG. 1 100 SPL in dB 90 80 70 Impedance Figure 2 shows impedance with frequency. 500 1k 2k 5k 10k 20k 40k 20 50 100 200 500 1k 2k 5k 10k 20k 40k frequency in Hz FIG. 2 20 10 5 frequency in Hz FIG. 3 distortion in dB -10 30 -20 10 -30 3 -40 1 -50 20 50 100 200 500 1k 2k 5k 10k 20k 40k 500 1k 2k 5k 10k 20k 40k frequency in Hz distortion in % 100 0 .3 beamwidth in degrees 300 200 50 20 vertical horizontal 10 5 20 50 100 200 frequency in Hz 25 200 100 20 50 15 20 10 10 5 5 0 directivity factor Q (R) FIG. 4 100 20 50 100 200 500 1k frequency in Hz 2k 5k 10k 20k 40k 1 D.A.S.

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. 100 2 directivity index Di in dB Polar Response Figure 6 shows the one octave band horizontal (solid) and vertical (dashed) polars for the indicated frequencies. Full scale is 50 dB, 5 dB per division. 50 100 Beamwidth Figure 4 shows the -3, -6 and -10 dB horizontal (solid) and vertical (dashed) beamwidth with frequency curves. -6 dB ones are shown with thicker traces for clarity. Axial Directivity Q(Rθ) and Di Figure 5 shows the above characteristics with frequency. Thin continuous and dashed lines show partial horizontal and vertical, respectively, characteristics. 20 200 impedance in Distortion Figure 3 shows the Second Harmonic Distortion (grey) and Third Harmonic Distortion (dotted) curves for a unit driven at 10% of its nominal power handling rating. 60 02/01 Frequency Response Figure 1 shows the frequency response at 1 m of a unit radiating to a half space anechoic environment and driven by a 1 W (2.83 V) swept sine signal.
