Celestion : T1221: Classic Series 12" 25W Speaker 16OHM

Celestion's first guitar loudspeaker featuring a ceramic magnet structure the G12M Greenback presented almost as much magnetic flux to the voice coil as an Alnico formulation but in a much more compact space. As a result the Greenback became the guitar loudspeaker that paved the way for use with higher power amplifiers. And of course the ceramic magnet presented its own unique tonal characteristics.The Greenback has a loud and assertive character that sounds great through a valve amp pushed into overdrive. The speaker has evolved over the decades and still presents that instantly familiar woody tone delivered with a knockout punch.Chassis type Pressed steelDC resistance re Available 6.7? or 13.1?Frequency range 75-5000HzMagnet type CeramicMagnet weight 35oz 0.99kgNominal diameter 12" 305mmNominal impedance Available 8? or 16?Power rating 25WrmsResonance frequency Fs 75HzSensitivity 98dBVoice coil diameter 1.75" 44.5mmVoice coil material Round copperMounting InformationCut-out diameter 11.1" 283mmDiameter 12.2" 309mmMagnet structure diameter 5.9" 150mmMounting slot dimensions 0.31" 7.9mm ØMounting slot PCD 11.7" 297mmNumber of mounting slots 4Overall depth 5.1" 130mmUnit weight 7.9lb 3.6kg
