Description

large size venues demanding high SPL and reliability. It
helps building perfect playback system cooperating with T
Series full range products.
Band-pass design helps T212B 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).
T212B is good for carnival and permanent installation.
Laminated board from China painted with polyurethane
guarantees super weather resistance. Two stands, 8*50mm
rubber feet and caster installation points are attach to the
loudspeaker which provides convenient installation,
stacking and removal.
T212B is a compact subwoofer. It is used in middle to

Speaker Testing Method
1. Frequency response
Use Pink noise to test the speaker in the anechoic room, adjust
the level to make the speaker work at its rated impedance and
the power output is 1W, then test the frequency response 1m
away from the speaker.
2. Sensitivity
Use full range Pink noise which was modified by EQ curve to
test the speaker in the anechoic room, enlarge the signal to
make the speaker work at its rated impedance and the power
output is 1W, then test the sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise which was modified by EQ curve to
test the speaker in the anechoic room, enlarge the signal to
make the speaker work at its instant power output level, then
test the SPL 1m away from the speaker.
4. Rated Power
Use the pink noise according to IEC#268-5 to test the speaker,
enlarge the signal for continuous 100hours, the rated Power is
the power when the speaker will not incur hot damage or
mechanics damage.
