A1.1200

A1 REALISTIC REPRODUCER

The modern field-coil loudspeaker compromises between dimensions and low frequency reproduction. Similar to Altec’s exceptional paper cone with textile suspension our 11.5 inch large A1.1200 is capable to reproduce all notes up to 2 kHz without the ringing of it’s competitors. Also our ventilated spider conforms to recent perceptions without the problem of loosing the restoring force due to excessive displacement. As the A1.1200 is efficient and this transducer uses an underhung voice coil the maximum amplitude is confined meaningful.
