Pinpoint (Blade)   Floorstanding as in K+T 4/2015

Technical data
  • impedance: 4 Ohm
  • sensivity (2,83V/1m): 85 dB
  • size (HxWxD): 1150 x 200 x 300 mm
  • frequency range (-8dB): 39 - 21000 Hz
  • crossover frequency(s): 400 Hz
  • speaker type: bass reflex

Pinpoint is a 2 Way F.A.S.T (Fullrange and subwoofer technology) floorstanding speaker with a design like KEF Blade. The kit is delivered with Visaton B80 as fullrange driver and 4 woofer Visaton W 100 S 8 Ohms.

The crossover for the fullrange driver is a first order high-pass filter in series to a rejector circuit and a drain circuit to damp the loudness about 2000 Hz. The filter for the Woofers is a second order low pass with a drain circuit to linearize the impedance.

Between 100 Hz and 8000 Hz, the frequency response of this loudspeaker is very linear on axis, above 8000 Hz the response rises up to 5 dB. The increase of the sound pressure above 5000 disappears at the directivity measurements with 15 or 30 degrees. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.5% above 300 Hz and rises not over 1% at 95 dB at 1 m .

Kit with high-end crossover

On important parts the high-end kit is delivered with baked varnish air coils 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. In the filter for the fullrange driver are polypropylen (MKP) capacitors instead of polystyrol (MKT) capacitors.

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 5,55 excl. VAT: € 4.66 / $ 5.04

universal PCBs

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 / $ 4.27
We recommend two boards per kit (4 boards per speaker pair)
