Neris is a two way floorstanding speaker.

Neris is a bass-reflex cabinet loudspeaker with drivers of SB Acoustics and Wavecor.

The kit is delivered with the following drivers:
- a SB Acoustics SB26ADC-C000-4 tweeter
- two Wavecor WF182BD14 woofers

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

The crossover consists of:
- a 3rd order high-pass filter (18 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 0,3% above 300 Hz and doesn't exceed 0,8% 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 SB Acoustics SB26ADC-C000-4 are of type polypropylen (MKP) Mundorf Mcap Supreme EVO Öl 800 V.

  • Mundorf MCAP EVO 12 μF / 450 V
  • Mundorf MCAP EVO Oil 10 μF / 450 V
  • Mundorf MCAP EVO Oil 22 μF / 450 V
  • Mundorf Mcap Supreme EVO Oil 2,2 μF / 800V
  • Mundorf baked varnish air core coil BL71, 0.18 mH/0.34 Ohm
  • Mundorf baked varnish air core coil BL140, 1.5 mH/0.38 Ohm

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 47 μF / 160 Vdc
  • 0.7 mm air core coil, 0.47 mH/0.50 Ohm
  • ceramic resistor 5.6 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 18,60 excl. VAT: € 15.63 / $ 16.88

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 / $ 4.27
We recommend one board per kit (2 boards per speaker pair)
