DayDream is a two way floorstanding speaker.
DayDream is a bass-reflex cabinet loudspeaker with drivers of Dayton Audio .
The kit is delivered with the following drivers:
- a Dayton Audio NHP25Ti-4 tweeter
- a Dayton Audio RS150-4 woofer
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is perfectly linear.
The decay spectrum is nearly perfect.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1,2% above 200 Hz.

Kit without cabinet, price per speaker EUR 107,23 excl. VAT: € 92.44 / $ 108.15
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 Dayton Audio NHP25Ti-4 are of type polypropylen (MKP) Mundorf MCAP EVO Öl 450 V.
Kit with high-end-crossover without cabinet, price per speaker EUR 141,34 excl. VAT: € 121.84 / $ 142.56
Optional high frequency series RLC resonance circuit to reduce the tweeter resonance around 21 KHz
Price per series RLC resonance circuit for one speaker. EUR 6,37 excl. VAT: € 5.49 / $ 6.42
Price per series RLC resonance circuit for one speaker. EUR 7,71 excl. VAT: € 6.65 / $ 7.78
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 8,85 excl. VAT: € 7.63 / $ 8.93
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. I-2765, price per unit: EUR 3,61 excl. VAT: € 3.11 / $ 3.64
We recommend one board per kit (two boards for a speaker pair)
