Celestion 12" Co-axial Loudspeaker
Handling 20 watts RMS and covering a frequency range of 30 Hz to 18
kHz, this loudspeaker has a moulded foam surround and a horn-loaded treble
unit. This treble unit gives wide dispersion of the high frequencies and has a
"brilliance" control so that the level can be adjusted to suit room
conditions
Features:
1.Hi-Flex "free" surround - provides
high compliance, eliminates standing waves and surround resonance.
Guaranteed moisture resistant.
2.Two Voice Coils
- extra long bass voice coil and precision mounted H.F. coil ensure clean
extended frequency coverage.
3.Compression
horn loaded treble unit - for linear and wide angle distribution of high
frequencies.
4.High flux
ceramic magnets - ensuring high input/output ratio
5.Pure electrical
cross-over - provides smooth frequency transition and feed to the
appropriate voice coil
6.Rigid die-cast
chassis - giving permanent precision alignment
7.High Frequency
