celestion - tn1230 300w 8ohm - lf pressed steel chassis loudspeaker - neodimio altoparlante da 12". con chassis in acciaio stampato. magnete in neodimio. bobina da 3".. potenza 300watt. impedenza 8ohm

caratteristiche - 12". bass and mid-range speaker driver unit provides 300wrms (aes standard) power handling and 97db sensitivity - 3". high-temperature copper voice coil wound on polyimide for increased reliability - fea optimised neodymium magnet assembly design for lower weight and reduced harmonic distortion - ".m-roll". surround provides progressive excursion control yielding a smooth response curve at extremes of frequency range - kevlar-loaded cone with sealed surround and damping contributes to lower distortion - rigid chassis design for maximum energy transfer

note (1)tested for two hours using a continuous. band-limited pink noise signal as per aes standard. power calculated on minimum impedance. loudspeaker tested in free air. (2)continuous power rating is defined as 3db greater than the aes rating. (3)measured on axis at 1w. 1m in 2pi anechoic environment. (4)xmax derived from: (voice coil winding width-gap depth)/2. (5)small signal parameters measured after unit subjected to pre-conditioning signal.
