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.
