We have applied the below technique to minimize the size:

1. One piece metal speaker enclosure

   Unlike wooden enclosure, metal enclosure gives the strong hold at a smaller size

2. High efficient Class D digital amplifier

   Unlike conventional bulky Class A or Class AB amplifier, Class D digital amplifier works at a higher efficiency in a compact size

3. High capacity Panasonic lithium battery
   We use high capacity lithium battery to reduce the number of battery used in the speaker.

4. Single chip design
   We use a highly integrated single chip to minimize the number of external component.

   The simpler the design, the more reliable the speaker is.

5. All-in-one software

   We use all-in-one software to give various features which can be easily controlled.

6. Fully digital design
   From input to output, it is a fully digital design. There is no bulky analogue component.

7. Sound engineering by advanced technology.
   Unlike other audio brands, we are not just adding different expensive components together to adjust the sound. Instead, we tune the sound by our advanced technology.
