HiFi-PA 2x8/2 is a two way floorstanding speaker.
HiFi-PA 2x8/2 is a bass-reflex cabinet loudspeaker with drivers of Celestion and Monacor.
The kit is delivered with the following drivers:
- a Monacor horn MRH-180 with Celestion CDX1-1747 driver
- two Monacor SP-8/150 PRO woofers
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 tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum is perfect.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,6% above 100 Hz.

Kit without cabinet, price per speaker EUR 385,00 excl. VAT: € 323.53 / $ 381.76
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 Monacor MRH-180 mit Celestion CDX1-1747 are of type polypropylen (MKP) Mundorf EVO Öl.
The kit with high-end crossover also has a higher load capacity, as the coils in series with the two woofers have a cross-section of 1.8 mm2 instead of only 1.4 mm2.
Kit with high-end-crossover without cabinet, price per speaker - not available
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).
If you prefer to mount the crossover components on a 140 x 102mm universal PCB instead on wood:

We recommend two boards per kit (four boards for a speaker pair)
