A1.1500 Kilimanjaro-Series

A1.1500 Bass Midrange Transducer

Inspired from an original Lansing 815, the former successor of the 15XS and the precursor of the 604, the A1.1500 uses a phenolic compound spider with similar shape but flat style. The primary aim was long term stability and linearity of the restoring force. The all paper cone edge is treated from behind and afterwards clamped to our soft aluminum front. Extremely rigid studs hold the heavy high current field-coil motor. The outcome is a realistic performer which bears comparison with every highly sought-after original vintage drive unit.
