1) TS-15A02: 15" subwoofer x1 + 2" Nd magnetic driver x24; TS-15A03: 15" subwoofer x1 + 3" Nd magnetic driver x24;

2) Using reversed phase hole to reduce distortion;

3) Splicing arrangement design to cover larger area while using less speakers; even in complicated acoustic environment, it could realize perfect audio transmission;

4) The speaker is with internal 2 channel digital amplifier; 1 is for subwoofer and the other is for full range speakers;

5) Using PWM power amplifier to realize no nonlinear distortion; auto recovery back electromotive force of speaker drivers;

6) With internal 2 in 2 out pro sound processor whose S/N ratio is 110dB; sampling rate 96KHz/24Bit;

7) The audio processor works with power amplifier perfectly and the state signal of the power amplifier dynamic control the compensation created by the processor; the sound processor provides amplifier with base clock to achieve instruction synchronization;

8) The audio processor is integrated with EQ, distributor, delayer, suppressor, noise-gate, etc;

9) Using dual-phase power to supply continuously in large dynamic; using fixed-frequency switching power to avoid interference by frequency drift and beat signal;

10) Using the loop matching the feature of audio amplifier to speed up power supply and to ensure power supply in fast switching between unload and full-load;

11) The precise design of frequency point optimize power response and restore the voical part perfectly;

12) Complete protection function to provide short protection, over current protection, over-temp protection and over/under voltage protection;

13) The subwoofer box is made of plywood in 18mm which is light and treated by wear proof spray; and it’s pasted by dust proof cotton net; the sound box of linear full range speaker is made of brushed aluminum alloy in 3mm which is treated by wear proof spray;

14) The whole speaker uses removable combination design; there’s a threaded hole on the top of the subwoofer for linear full range speaker with thread.
