Product Description
Manufacturer Part Number: FTX0820
Celestion's unique FTX0820 coaxial full-range driver uses a single FEA optimized magnet as the common motor for both the 8" low frequency and 1.4" compression driver resulting in enhanced coherence and minimal distortion.
Key Features:
Celestion FTX0820 8" Coaxial Full-Range Professional Driver
Perfect for ultra-compact high output speakers systems, Celestion's FTX0820 8" coaxial full-range features fully integrated low and high frequency drivers which are powered by a common motor assembly. Bringing the acoustic centers of the two drivers closer together improves both time alignment and signal coherence for more natural and predictable response. Other features include an aluminum demodulation ring, edgewound voice coils (woofer and compression driver), and a cast aluminum frame with integrated voice coil vents.
By concentrically aligning low and high frequency drivers, coaxial loudspeakers act as a single source, often providing improvements in signal alignment when compared to a traditional two-way system. Powered by a common magnet motor assembly (same magnet for both elements) Celestion's FTX coaxial range features fully combined LF and HF components in a single chassis. This brings the voice coils and hence the acoustic centers of the two drivers closer together, delivering further improvements in signal coherence for a more natural sounding audio reproduction.

Celestion's unique FTX0820 coaxial full-range driver uses a single FEA optimized magnet as the common motor for both the 8" low frequency and 1.4" compression driver resulting in enhanced coherence and minimal distortion.
Key Features:
- Capable of true full range frequency response from 70 to 20,000 Hz
- Coaxially mounted 1.4" Polyimide compression driver delivers predictable off axis response
- Demodulation ring lowers inductance and improves damping for lower distortion
- Rugged cast aluminum frame is designed to minimize unwanted reflections
- Can be used with both passive and active crossovers (not included)
