Oka is a loudspeaker that should be used as wall speaker. To do so there are two possibilities: You can build the speaker as floorstander or you build it as shelf speaker that can be fixed to a wall.
Oka is developed by Dennis Frank und Daniel Gattig as bass reflex system.
The harmonic distortion is low (mostly less than 0.2% above 300Hz at 85 dB/1m). The decay spectrum is without any fault.

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 240 x 165 mm universal PCB instead on wood: Universal PCB RA240, order no.. str-RA240, price per unit: EUR 8,60 excl. VAT: € 7.23 / $ 7.44 We recommend one board per kit (two boards for a speaker pair)
