TW8
Description
β3 TW8 is two way wide-dispersion full range speaker which
adopts the new structure and patented horn design.
It integrates one 8" woofer and one 25mm compression driver.
The voice coil in the woofer uses the round copperclad alumi-
nium wire of inside and outside wrap technology, the TIL back-
bone enhances the heat dissipation of the voice coil and impr-
oves the power handling of the woofer too. Symmetrical mag-
net order harmonic distortion tocircuit design reduces the odd
lower level. The 34mm 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 100W, Max. power reaches to 400W.
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.

TW Series Pro Loudspeaker System CONNECTION
Push Terminals
The 4 way push terminal connectors are available for amplifier connections. Paralelled connector is very convenient for
another speaker connection.
Attention: The impedance of connected speaker must match the impedance of amplifier output.
Attention: Make sure the polarity of speaker and amplifier correctly.

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
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 of 100 hours, the
rated power is the power when the speaker will show no visible
or measurable damage.
