TW Series Pro Loudspeaker System
INTRODUCTION
BetaThree TW12 is two way wide-dispersion full range speaker
which adopts the new structure and patented horn design.
It integrates one 12" woofer and one 44mm 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 44mm flat
voice coil in the compression driver develops the magnetic
energy efficiently to both enhance the intensity of
the voice coil and increase the power handling.The rated
power reaches to 250W, Max. power reaches to 1000W.
Cabinet is made of birch plywood with advanced
environmental protection Polyurethane-based painting
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.
One 12 High Power LFT ." ransducer
One 44mm HF Driver.
Computer aided design to optimize frequency and
phase response.
Frequency Response 50Hz - 20kHz (-3dB).
Sensitivity 95dB, MAX. SPL 115dB/121dB(PEAK).
Rated Power 250W(RMS), 1000W(PEAK).
Durable Polyurethane textured base paint.

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 at 1W, then test the frequency responsepower
1m away from thespeaker.
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 ratedsignal to make the speaker
impedance and set the thepower 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
increase the work at itssignal to make the speaker
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.
