Apogee - Caliper Speaker set

No longer in use for 2 years, no problem during the last uses\n\nThe Signature model was a complete redesign of the original Caliper: the speaker and the passive filter were modified, only the outer enclosure remained unchanged.\n\nThe result was a speaker easier to drive than the original model, offering better-controlled bass and a better overall balance.\n\nIt was possible to upgrade a Caliper to Signature specifications, which required replacing the passive filter and the two speakers.\n\nSpecifications\n\nHeight\n121 cm\n\nWidth\n61 cm\n\nDepth\n7 cm\n\nBass speaker\nAluminium/Kapton panel\n\nMid/treble speaker\nAluminium/Kapton (3 segments)\n\nMaximum SPL\n103 dB\n\nSensitivity at 3 m\n84 dB\n\nFrequency response\n40 Hz (-3 dB) 20 kHz\n\nCrossover frequency (acoustic)\n1 kHz\n\nRecommended amplification power\n100 W (at 8 ohms) 200 W (at 4 ohms)\n\nNominal impedance\n3 ohms\n\nWeight\n32 kg (per unit)\n\nFinishes available\nLight grey, anthracite or taupe
