Inside the speaker, a diaphragm sits on top of a voice coil to produce a signal waveform once an input signal is received. It transforms the signal wave into a sound wave. Polypropylene is one of the lightest plastics ever invented and is great material for speaker diaphragms due to its weight, high strength, stiffness and tolerance of high temperatures. These polypropylene cones deliver high quality music by reacting to even the smallest sound signal to produce clear, vivid sound.

A highly sensitive cloth connects the woofer diaphragm to the speaker frame to form a surround suspension system. When a sound signal reaches the cone inside the woofer, the cloth surround assembly brings the cone back into position so it's ready to receive another sound signal. By doing so, the woofer can capture every signal with minimum distortion, giving you clear, smooth sound no matter how loudly or how quietly the music is played.
