TH612 is a combination of a 12" paper cone MIDLOW driver with high quality aluminum bracket and a
powerful penetration compression driver with 44mm titanium diaphragm. It features a fine-tuned passive
crossover and HF horn ultra-long and efficient transmission dispersing 70° 50°.
Trapeziform enclosure could be used as main speaker and monitor speaker. The reserved 10 M10
rigging points ensure easy setup and angle adjustment for fixed installation and tour shows.
The enclosure is formed by 18mm plywood with waterproof and black texture finish.
Two handles are placed at both sides for handy carry.The two SPEAKONS are in parallel connection. There
is a piece of acoustic form covered under the grille which could provide better protection towards the
components.

TH615 is a combination with a 15" paper cone MIDLOW driver with high quality aluminum bracket and a
powerful penetration compression driver with 75mm titanium diaphragm. It features a fine-tuned passive
crossover and HF horn ultra-long and efficient transmission dispersing 60° 40°.
Trapeziform enclosure with angle 12°or 43°which could be used as main speaker and monitor speaker.
The reserved 10 M10 rigging points and one 35mm pole mount socket ensure easy setup and angle
adjustment for fixed installation and tour show. The enclosure is formed by 18mm plywood with
waterproof and black texture finish.TH615 is integrated with two handles at both sides for
convenient hand carry.The two SPEAKONS are in parallel connection. There is a piece of acoustic form covered under the grille which could provide better protection towards the
components.

Dual 15" two-way design deliver high SPL, it delivers the clarity required for speech and music application
as well as the power, warmth and depth to generate and exciting live sound or playback experience in
nightclub.

TH625 is a combination with dual 15" paper cone MID-LOW driver with high quality aluminum bracket
and a 75mm titanium compression driver coated with diamond-like material which greatly helpful to extend
performance of high frequency towards high sound resolution.

The crossover designed with suppression circuit for high frequency absorbs extra peak points, which
complements the inherent defect of titanium diaphragm voice coil and make the frequency
response more smoother. It features a HF horn with efficient transmission dispersing 60° 40°.Trapeziform enclosure with angle 18° for both sides could be used as main speaker and monitor speaker.
The reserved 10 M10 rigging points and one 35mm pole mount socket ensure easy setup and angle
adjustment for fixed installation and tour show. The enclosure is formed by 18mm plywood with
waterproof and black texture finish.

TH625 is integrated with two handles at both sides for convenient hand carry. The two SPEAKONS are in
parallel connection. There is a piece of acoustic form covered under the grille which could provide better
protection towards thecomponents.

TH625B is equipped with dual 15" paper cone constant directivity woofers. With some special
designs such as 4” powerful voice coil winding not only inner but also outer, heat sinking by aluminum
ring which built in Tiron, 220 high magnetic energy, generally increased bearing capabilities for
continuous high power input. It is designed for applications where low frequency is
highly required such as concert hall,theater, performance center, disco etc. TH625B is the first
choice for high power, large dynamic range and high SPL applications.
The upper socket design makes it possible to mount with other TH600 speakers.
The enclosure is formed by 18mm plywood with waterproof and black texture finish.
TH625B is integrated with two handles at both sides for convenient hand carry.

The two SPEAKONS are in parallel connection. There is a piece of acoustic form covered under the grille

TH618B II subwoofer is developed with special purpose of achieving ultra low frequency and higher output. So a brand new highly qualified 18"LF driver is greatly needed.

The paper cone is re-designed and the spider is modified to eliminate the airflow noise while it's used at large dynamic range. Af ter the magnetic circuit is modified as well and the stroke of voice coil is increased,the original paper cone and frame are found incapable of meeting the requirements. The paper cone and frame have to be changed. spider is further improved. Even the wiring method is re-designed for the purpose. The subwoofer delivers powerful, low-ranging and dynamic bottom-end response deep to 30Hz-50Hz with lower nonlinear distortion and higher output af ter the specification of T/S is adjusted and the space of inverted phase tube is enlarged.

We didn't get the current brand new 18"woofer until the 8th sample was successfully made.
The TH618B is a subwoofer designed to extend low-range frequency response It is loaded with a directradiating 18" cone loudspeaker housed in a phase inverted enclosure. The Sub delivers powerful, low-ranging and dynamic bottom-end response deep to 30Hz.

It is finely suited for application in which a sound system requires a more punching low-frequency
reinforcement.
