Description
TW215 is two way wide-dispersion full range speaker
It integrates dual 15" woofer and one 75mm compression
driver. The voice coil in the woofer uses the round copper-
clad aluminium wire of inside and outside wrap technology,
theTIL backbone enhances the heat dissipation of the
voice coil and improves the power handling of the woofer
too. Symmetrical magnet circuit design reduces the odd-
order harmonic distortion to lower level.The 75mm flat
voice coil in the compression driver develops the magnetic
energy product efficiently to both enhance the intensity
of the voice coil and increase the power handling.The
rated power reaches to 500W, short term Max. power
reaches to 2000W. .
which is very rigid.The strength of cabinet itself reaches
to 4500N. Each suspension point can bare 3000N. Q235
grille with powder coating provides strong ultra weather
resistance, which can be used outdoors for 5 years.The
backside foam of grille prevents the getting in of the rain.
Features
3-transducer 2-way Full Range Speaker.
Dual 15" High Power LF Driver.
One 75mm HF Driver.
Computer aided design to optimize frequency and
phase response.
Frequency Response 45Hz - 18kHz (-3dB).

SpeakerTesting 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 power at 1W, then test the frequency response
1m away from the speaker.
2. Sensitivity
Use full range Pink noise which has been modified using
an EQ curve to test the speaker in the anechoic chamber,
increasing the signal to make the speaker work at its rated
impedance and set the power output at 1W, then test the
sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise which has been modified using
an EQ curve to test the speaker in the anechoic chamber ,
increase the signal to make the speaker work at its
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.
