1. Straight squareness，delicacy and decent ;
2.Easy to carry；economization energy and longevity;
3. High quailty full frequency loudspeaker，insue to play with fidelity;
4.Designing for IPOD\MP3\CD\MD\MOBILE and so on moving speaker;
5.Power is supplied by batteries;
6.Designed for IPOD specially,It can be present.

2-way 4th vented active monitor multimedia speaker system

The IRW-289 comes standard with two wireless microphones. It uses bass-treble and volume control for compensation, when wire and wireless microphone can be used in the same place.
This system is especially suitable for such small rooms as KTV, karaoke, churches or meeting rooms.
Ifrared microphone system which entirely avoid the usual frenquency interference problem for wireless microphone.

1.It's compact ,light and with ultra-thin exterior ,can take along with it .The perfect sound annotated the ultra-thin；
2. It augmented the functions of Ipod and instead of using earphone to listen,showed the high quality sound everywhere；3. With the prominent MAXXBASS technology ,no need for the low sound space it also has the high quality of low sound effect；
4. Using two pieces of 2.1inch flat board and full frequency loudhailer make the sound field wilder,and displayed better；
5.LCD show the speaker's working state, that make the operation more frank and convenient；
6.It supports FM setting radio,showing the FM frequency ,can hand control or auto-search the channel ,and it can save the channel too；
7. It has alarm and clock functions,and can choose the alarm mode too,can set the Ipod as a music alarm ；
8. Can use the AUX out sound ,using attached audio wire can connect with the MP3\CD player and so on conveniently；
9.All the functions can be controlled by the remote control；
10.Connected with the electrical adspter ,it can auto-recharge for the Ipod autoly。
