Asterion is a three way compact speaker.
Asterion is a bass-reflex cabinet loudspeaker with drivers of SEAS .
The kit is delivered with the following drivers: - a SEAS MR18REX/XF (H1699-08-06) coaxial driver - a SEAS CA22RNY (H1471-08) woofer
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of: - a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. - a band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 3rd order low-pass filter (18 dB per octave slope) for the mids-woofer. - 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 as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 300 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.
"But even without subwoofer support, the Asterion really nails the bass. The CA22RNY is an old-style-woofer just the way I like it: With a little cabinet volume, it can produce a highly dynamic and at the same time light-footed bass, which is always a bit reminiscent of the classics of the 70s, when you couldn't get deep tones out of stiff and heavy cones, but out of large cabinets. One can forgive the box the missing sub-octave, because it otherwise sounds so incredibly rich and deep. The coax does a very good job in the midrange and high-frequency range - tonally, everything is just on-point, adjusting the personal sound preference is easily possible by directing the tweeter directly to the listening position or a bit off-axis. And then of course there is the spatial illusion - a home game for the Seas-Coax, which sets standards both in the dimensions of the stage image and in the precision in the positioning of voices and instruments. And so you can enjoy everything from rock to classic with the Asterion - a perfect all-round-speaker."
"The Asterion is a box for all music genres - compact, dynamic and with an impressive spatial image."

Kit without cabinet, price per speaker EUR 692,00 excl. VAT: € 581.51 / $ 633.85

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 SEAS MR18REX/XF (H1699-08-06) are of type polypropylen (MKP) Mundorf Mcap Supreme EVO Öl 800 V.
Kit with high-end-crossover without cabinet, price per speaker EUR 825,00 excl. VAT: € 693.28 / $ 755.67
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 8,00 excl. VAT: € 6.72 / $ 7.33
If you prefer to mount the crossover components on a universal PCB instead on wood PCB 220x155 mm, order no. I-8805002, price per unit: EUR 11,80 excl. VAT: € 9.92 / $ 10.81 We recommend one board per kit (2 boards per speaker pair)
