Quintett Nano is a three way floorstanding speaker.

Quintett Nano is a bass-reflex cabinet loudspeaker with drivers of Visaton .

The kit is delivered with the following drivers:
- a Visaton FRS 5X, 8 Ohm full range driver
- a Visaton W100 S, 4 Ohm mids driver
- four Visaton W100 S, 4 Ohm woofers

The loudspeaker has been developed by Holger Barske and Thomas Schmidt.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- a band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 2nd order low-pass filter (12 dB per octave slope) for the mids-woofer.
- a 2nd order low-pass filter (12 dB per octave slope) for the four woofers.

The frequency response of this speaker is nearly linear.

The decay spectrum (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.

At low volume, i.e. 80 dB at 1 m, the nonlinear distortions are below 0,8% above 200 Hz and doesn't exceed 1,2% at 90 dB at 1 m between 300 and 15000 Hz.

The mounting ring for the Visaton FRS 5 X is not included in the kit

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 Visaton FRS 5X, 8 Ohm are of type polypropylen (MKP) ClarityCap 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).

  • Audaphon MKT CAP 4.7 μF; / 160 Vdc
  • 0.7 mm air core coil, 0.39 mH/0.49 Ohm
  • ceramic resistor 6.8 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 7,90 excl. VAT: € 6.64 / $ 7.90

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 / $ 5.90
We recommend one board per kit (two boards for a speaker pair)
