Beyma 15CXA400FE - Coaxial 15" 8ohm 98/105dB 400/80W Ferrite

The Beyma 15CXA400Fe full-range coaxial speaker eliminates phase issues while ensuring optimal audio dispersion, and can still be installed in a nice and compact speaker cabinet. Boasting an LF AES power rating of 400 Watts and a HF AES power rating of 80 Watts at 8 to 16 Ohms, the 15CXA400Fe brings more than enough output, while the woofer features a ferrite magnet and 4-inch voice coil for a 98 decibel SPL, and is balanced by the treble output of a 2.85 inch compression driver with a 105 decibel SPL to deliver a 35Hz to 20,000 Hertz frequency range. This speaker is also kitted out with a specialised titanium and polyester composite HF diaphragm to ensure natural sound.
