Diva Simone   Floorstanding as in K+T 4/2015

Technical data
  • impedance: 4 Ohm
  • sensivity (2,83V/1m): 85 dB
  • size (HxWxD): 970 x 200 x 330 mm
  • frequency range (-8dB): 38 - 30000 Hz
  • crossover frequency(s): 350, 3800 Hz
  • speaker type: bass reflex

Diva Simone is a classic 3 way floorstanding speaker with ribbon tweeter, the engineeering is from Jens Heerklotz alias "Sonic-Fury" . The kit is delivered with Monacor MSH-115HQ for the midrange, two woofers Monacor SPH-145HQ and Monacor RBT-10 ribbon tweeter for the high frequencies.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter, a bandpass filter (6 dB high - and 18 dB lowpass) for the two mids. The woofer is connected to a 1 st order low-pass filter.

The frequency response of this loudspeaker is nearly linear on axis. An elevation in the frequency characteristics occurs at 3000 to 22000 Hz, but this should not disturb. Small gaps at 1500 and 3000 Hz is no problem in sound quality. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 1.5% above 200 Hz and rises not over 3% at 95 dB at 1 m .

Kit with high-end crossover

The high-end kit is delivered with baked varnish air coils on important parts 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 in series to the speakers are polypropylen capacitors (MKP) insetad of polystyrol capacitors (MKT). In the filter for the tweeter are top quality ClarityCap capcitors of type ESA.

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).

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 19,40 excl. VAT: € 16.30 / $ 17.44

universal PCBs

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 / $ 4.23
We recommend three boards per kit (6 boards per speaker pair)
