I recently found this amazing vintage Jensen Concerto speaker kit at a local estate sale. The model is KT-21. It is in its original box and appears to have never been installed in a speaker cabinet. Set consists of the following units:

  •  Jensen 15" P15-LL L-F (Low Frequency) Driver
  • Jensen RP-102 H-F (High Frequency) Compression Horn Driver
  • Jensen A-204 Crossover Network (crossover frequency is 2000 cycles)
  • Jensen Balance Control

The impedance is 16 ohms. 

I found a copy of a Jensen product manual on-line from 1956 that has a full description of the KT-21 kit. It recommends a speaker cabinet of 10 cubic feet!

Set will be double boxed for shipment and insured.
