Narmada is a two way compact speaker. It is characterized by high efficiency and low non-linear distortion. Il se caractérise par un rendement élevé et une faible distorsion non linéaire.
Narmada is a bass-reflex cabinet loudspeaker with drivers of Audaphon and Wavecor.
The kit is delivered with the following drivers:
- a Audaphon AMT 1i, runde Frontplatte tweeter
- a Wavecor WF259PA01 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 3rd order low-pass filter (18 dB per octave slope) for the woofer.
The frequency response of this speaker is perfectly linear.
The decay spectrum is perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 200 Hz and doesn't exceed 0,6% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 975,00 excl. VAT: € 819.33 / $ 893.07
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 Audaphon AMT 1i are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

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).
If you prefer to mount the crossover components on a universal PCB instead on wood
