DayDream Sat is a two way compact speaker.
DayDream Sat is a closed-cabinet loudspeaker with drivers of TECTONIC and Dayton Audio.
The kit is delivered with the following drivers:
- a TECTONIC TEBM46C20N-4B full range driver
- a Dayton Audio RS125-4 woofer
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear (except the treble).
The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,4% above 300 Hz.

Kit without cabinet, price per speaker EUR 182,00 excl. VAT: € 152.94 / $ 162.12
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 TECTONIC TEBM46C20N-4B are of type polypropylen Audaphon MKP CAP Superior.

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 5,80 excl. VAT: € 4.87 / $ 5.17
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit: EUR 5,90 excl. VAT: € 4.96 / $ 5.26
We recommend one board per kit (two boards for a speaker pair)
