Features
The CX8A is a high efficiency 200W 8” coaxial speaker with a coaxially mounted 1″ high frequency driver available in a single 4 ohm (woofer) and 8 ohm (driver) configuration. It features a high quality Y35 magnet assembly and a 2” high power midbass coil which delivers excellent full range output in compact enclosures.
The paper cone and acoustically transparent dust cap provides smooth frequency response from 80Hz to 20kHz. Push terminals are provided for easy and secure wire connections.

Recommended Enclosures
For midrange applications, a 0.4 cu. ft. (11 litres) net sealed enclosure is recommended.
For midbass applications, a 0.8 cu. ft. (22 litres) net ported enclosure with a single 3” diameter port, 3.6” long is recommended. Use a 60Hz high pass filter with this enclosure.
Always use a 2kHz 12dB/oct high pass crossover on the high frequency driver, and a 80Hz 12dB/oct high pass crossover on the low frequency driver. Failure to do so will result in driver damage.
Replacement high frequency diaphragms are available.
