Specification
Technical data
Notes
Frequency range
22 Hz - 170 Hz
-6 dB in half-space conditions using
required processing.
Usable low-frequency response
19 Hz
-10 dB in half-space conditions.
Coverage window
Omni
Rated impedance
4 ohms parallel mode/8 ohms
independent mode
Sensitivity @ 1 watt
102 dB
Measured with 12 dB crest pink noise
@ 2 V
rms
in half-space conditions with
required highpass filter and lowpass
filter.
Power handling
1,600 W @ 80 V
rms
12 dB crest pink noise for two hours
with required highpass filter and
lowpass filter, based on AES2-2012
standard, calculated power based on
rated impedance.
Power draw
1,140 W
Measured average power over five
seconds at the rated V
rms
using 12 dB
crest pink noise with required
highpass filter and lowpass filter. This
measured power draw from the
amplifier is useful for estimating
amplifier sizing in overall system
design.
Maximum voltage peak
200 Vpk
Measured Vpk over 100 hours using a
Hann-shaped sine-wave burst at the
maximum excursion frequency of the
system. This data is useful for setting
peak stop limiters and amplifier
selection.
Maximum continuous sound pressure
level (SPL) @ 1 meter
134 dB
Calculated from rated sensitivity and
power.
Measured acoustic peak SPL @ 1
meter
144 dB
Measured peak SPL over five seconds
at rated V
rms
using 12 dB crest pink
noise with required highpass filter and
lowpass filter.
SB218XL weight
207.5 lb (94.1 kg)
