NeXT-Monitor is a two way compact speaker, winning the IGDH-Contest 2017. Published in K+T 1/2018.
NeXT-Monitor is a loudspeaker with drivers of Seas . A Passive radiator provides deep bass.
The kit is delivered with the following drivers:
- a Seas 27TBCD/GB-DXT tweeter
- a Seas L16RNX/4 woofer
The loudspeaker has been developed by Alexander Wein.
The crossover consists of:
- a 2nd order high-pass filter (12 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 0.3% above 300 Hz and doesn't exceed 0.5% at 95 dB at 1 m between 500 Hz and 10000 Hz. That is quite splendid.
Standard and high-end kit contains:
the strandard kit crossover components, to be mounted on a small wooden board:
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 fullrange driver are of type polypropylen (MKP) Clarity-Cap PWA 160, ESA 630 and CSA (highest quality).
