Paper Cone vs PET Cone: What's the Sound Quality Difference?
When choosing a full-range speaker driver, the cone material is one of the most critical factors that determine sound performance, tone characteristics and application suitability. The two most common diaphragm types are pulp paper cone and PET plastic cone. Each has its own acoustic advantages and suitable usage scenarios.
1. Pulp Paper Cone 纸浆盆
Pulp paper cone is made of natural wood pulp with composite processing. It features moderate density, good internal damping and natural vibration characteristics.
Sound Performance
Midrange & vocal performance is outstanding: Paper cone delivers warm, clean and transparent human voice, with natural layering and delicate details.
Smooth and soft sound texture, no harsh sharpness at high frequency.
Excellent sound restoration, perfect for reproducing music, story telling and daily voice broadcast.
Solid and full low-mid bass, clear and not muddy.
Advantages
Natural acoustic damping, low distortion
Warm vocal tone, high fidelity restoration
More suitable for long-time voice playback without auditory fatigue
Best Applications
AI robots, children early education machines, sleep robots, white noise devices, smart speakers, indoor Bluetooth speakers and voice prompt equipment.
2. PET Cone PET 塑胶盆
PET cone is made of high-molecular polymer plastic material. It has high hardness, good rigidity and stable physical properties.
Sound Performance
High frequency is brighter and more extended, with crisp treble performance.
Hard cone structure brings better instant response and stronger explosive power.
Bass is tighter and more rigid, with good rhythm sense.
Midrange vocal is slightly colder and less warm compared with paper cone.
