Acoustics:
- 8" subwoofer driver; vented housing with port on back wall;
- 2-way satellite with 3" mid-range, and 3/4" tweeter unit with silk diaphragm;
- Complete wooden structure for all speakers; 12mm MDF for sub and 9mm MDF for satellites;
- Passive speakers with external amplifier Electrical:

General:
- Revolutionary voltage regulator circuitry to enable high VS for amplifiers and get best of the chips;
- Digital volume controller
- MCU for master volume, EQ control
- Power output: RMS 2 x 9W + 25W (bass seems not sufficient with 25W power, and study to optimize now)

Inputs:
- RCA inputs for PC on back of external amplifier;
- 3.5mm auxiliary inputs with higher sensitivity on both front panel and back panel of external amplifier; the one on back panel has higher priority of the two;
- Key control switches between the two inputs; input indicators on front panel of amplifier are lit accordingly (same as C2) Outputs:
- Speaker outputs on back panel of external amplifier, wire clippers;
- Headphone outputs on front panel of external amplifier; higher priority than speaker outputs;

Controls:
- Master volume control on front panel of amplifier;
- Input selector, Function (navigate recursively between master volume adjustment, treble adjustment and bass adjustment), and STBY/ON control available on front panel of amplifier (similar to C2);
- Master volume ranges from 0 to 60, and bass/treble trimmer ranges from -9 to +9, 1 on each step;
- Power On/Off switch available on back panel of amplifier;
- IR remote controller with STBY/ON, master volume control, bass/treble trimmer, input selector.

Cosmetic:
- Large metal cabinet for external amplifier;
- Large metal-looking damped volume knob;
