Vintage One   Shelf speaker as in K+T 1/2014

Technical data
  • impedance: 8 Ohm
  • sensivity (2,83V/1m): 85 dB
  • size (HxWxD): 490 x 215 x 280 mm
  • frequency range (-8dB): 49 - 38000 Hz

Vintage one is a classic monitor with Seas speaker drivers. Thomas Schmidt used the Seas dome 27TFF (KT27F) known for many years and the Seas CA18RLY paper cone woofer.

The crossover is designed as third-order filter (18db/octave slope).

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core coils on important parts of the crossover for minimizing microphonic effects. - The current flow through the coil creates a magnetic field which sets the reel of wire in motion. This motion induces a voltage in the coil which adds itself to the signal. The stiffer the reel of wire is, the less the signal will be altered. The capacitors for the fullrange driver are of type polypropylen Mundorf MKP 400 V.

Impedance correction

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 13,10 excl. VAT: € 11.01 / $ 12.77

universal PCB

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit:   EUR 5,90 excl. VAT: € 4.96 / $ 5.75
We recommend two boards per kit (four boards for a speaker pair)
