Hi,

Im trying to workout the frequency range of the drivers?

803S - Floorstanding

• 3-wy vented box system
• 150mm (6”) Kevlar cone FST midrange
• 25mm aluminium dome high-frequency
• 2 x 180mm (7”) Rohacell cone bass
• Sensitivity: 90dB spl
• Frequency Response: 35Hz - 22kHz ±3dB
• Recommended Amplifier: 50W - 200W
• Dimensions: 1063h x 291w x 433d 41kg

1. 25mm aluminium dome high-frequency = 4kHz to 22kHz
2. 150mm (6”) Kevlar cone FST midrange = 4Hz to ?
3. 180mm (7”) Rohacell cone bass = ? tp 35Hz

805S - Bookshelf

• 2-way vented box system
• 165mm (6.5”) Kevlar cone bass/ midrange
• 25mm aluminium dome high-frequency
• Sensitivity: 88dB spl
• Frequency Response: 49Hz - 22kHz ±3dB
• Recommended Amplifier: 50W - 120W
• Dimensions: 418h x 238w x 351d 11.5kg

1. 25mm aluminium dome high-frequency = 4kHz to 22kHz
2. 165mm (6.5”) Kevlar cone bass/ midrange = 4kHz to 49Hz
