Technical data
  • impedance: 8 Ohm
  • sensivity (2,83V/1m): 86 dB
  • size (HxWxD): 380 x 225 x 305 mm

Klang+Ton Falcon is a two way compact speaker.

Klang+Ton Falcon is a bass-reflex cabinet loudspeaker with drivers of Omnes Audio and Redcatt.

The kit is delivered with the following drivers:
- a Omnes Audio AMT 60.3 air motion transformer (ribbon-tweeter)
- a Redcatt Exclusive Hexacon 6 woofer

The loudspeaker has been developed by Thomas Schmidt and Blue Planet Acoustic.

The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 300 Hz and doesn't exceed 0,7% at 95 dB at 1 m between 300 and 15000 Hz.

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 Omnes Audio AMT 60.3 are of type polypropylen (MKP) Clarity-Cap ESA 630 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.     - not available (_)

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,70 excl. VAT: € 3.95 / $ 4.34
We recommend one board per kit (2 boards per speaker pair)
