Peter Mini K+T is a two way compact speaker.

Peter Mini K+T is a bass-reflex cabinet loudspeaker with drivers of SEAS and Wavecor.

The kit is delivered with the following drivers:
- a SEAS TFFNC/G (H1396-04) tweeter
- a Wavecor WF118WA07 woofer

The loudspeaker has been developed by Dennis Frank and Daniel Gattig.

The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.

The frequency response of this speaker is perfectly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,3% above 300 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.

An excerpt from the Klang+Ton review (Translation of the author into English)

"When listening on the desk or in the living room, the Peter Mini cuts an excellent figure and convinces with amazing dynamics, neutral tonality and really all-round qualities up to remarkable levels, which qualify it as fullrange speaker in smaller rooms."

Conclusion of the magazine Klang+Ton:

Surprisingly mature mini speaker with high sound quality.

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core 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. The capacitors for the SEAS TFFNC/G (H1396-04) are of type polypropylen (MKP) Clarity-Cap ESA 250 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).

  • JB, electrolytic capacitor, bipolar advanced, 22μF / 50 Vdc
  • 0.7 mm air core coil, 0.18 mH/0.36 Ohm
  • Metal-oxide resistor, 10W 5.6 Ohm (green-blue-gold)

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 8,30 excl. VAT: € 6.97 / $ 7.39

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 / $ 4.19
We recommend one board per kit (2 boards per speaker pair)
