speaker adopt trapezia design, it is convenient to form a cluster,
suitable for stage monitor, and reduce the standing wave inside the cabinet.
The well-chosen PLY with high intensity can absorb the exceptional sound
from the speaker cabinet’s syntony. has standard frying
construction and SPK socket input which is convenient for the installation.
are developed and produced by the combination of the latest
computerized stimulation design technology, the latest loudspeaker
materials and manufacture technology. All transducers adopt the most
optimized magnetic circuit having high magnetic energy, low distortion
and excellent ventilation. LF transducers use nonlinear thickness long
fabric paper cone with special painting cloth surround and high power
sandwich type voice coil. Symmetrical magnetic circuit was also adopted
and all these ensure the linear moving when LF works under high power.
The HF transducers take titanium diaphragm treated by high temperature
and rectangle voice coil and linear phase design compression chamber.
With the wide dispersion horn to get a wide sound covering field and our
new symmetrical protect circuit with adjustable delay, the sound and
product quality can be guaranteed.

to large size venues demanding high SPL and reliability. It
helps building perfect playback system cooperating with
TW Series full range products.
Band-pass design helps TW218B perform high SPL with
small volume. The driver uses high powered 100mm
diameter voice coil which is wrapped by copper wires
outside. Voice coil Skelton is made of TIL material that
improves the tolerance of voice coil power suffering.
Ferrite magnetic circuit provides very high BL and line
magnetic circuit.
Power compression reduces by good heat radiating
performance and harmonic distortion also does so by
iron choking ring limiting current. Rated power can reach
1000w and short max power is up to 4000w (GB/T9396-
1996 Standard).
TW218B is good for carnival and permanent installation.
Laminated board from China painted with polyurethane
guarantees super weather resistance. Rubber feet and
caster installation points are attach to the loudspeaker
which provides convenient installation, stacking and
removal.
218B is a compact subwoofer. It is used in middle

Frequency response curve & Impedance curve
TECHNICAL SPECIFICATION
Speaker Testing Method
1. Frequency Response
Use Pink noise to test the speaker in the anechoic chamber,
adjust the level to make the speaker work at its rated impedance
and set the output at 1W, then test the frequency response power
1m away from the speaker.
2. Sensitivity
Use full range Pink noise which has been modified using
an EQ speaker in the anechoic chamber, curve to test the
increasing the work at its rated signal to make the speaker
impedance and set the the power output at 1W, then test
sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise which has been modified using
an EQ speaker in the anechoic chamber , curve to test the
i n c r e a s e t h e wo r k a t i t s s i g n a l t o m ak e t h e s p e a k e r
maximum power output level, then test the SPL1m away
from the speaker.
4. Rated Power
Use Pink noise to the IEC#268-5 standard to test the speaker,
increase the signal for a continuous period of100 hours,
the rated power is the power when the speaker will show
no visible or measurable damage.
