Heka is a two way wall-mounted speaker.
Heka is a bass-reflex cabinet loudspeaker with drivers of SB Acoustics and Wavecor.
The kit is delivered with the following drivers:
- a SB Acoustics SB29BAC-C000-4 tweeter
- two Wavecor WF152BD05 woofers
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
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 nearly linear.
The decay spectrum is perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,7% above 300 Hz and doesn't exceed 0,7% at 95 dB at 1 m between 300 and 15000 Hz.
"Close to or directly on the wall, the Heka shows an amazingly deep and solid bass foundation, which is even suitable for home cinema with moderate demands on the dynamics - I tried it: At "Independance Day”, which was shown again recently, I had it at one point or another still missing the "big stuff” in terms of subwoofers, but the Heka reproduces everything on this side of blockbuster cinema surprisingly well. And that applies above all to music, which it reproduces lively, authentically and very neutrally - a true dream loudspeaker for all people with little space and very high demands."
The Heka is an uncompromising yet space-saving high-end solution for music and cinema fans alike.

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 SB Acoustics SB29BAC-C000-4 are of type polypropylen (MKP) Mundorf MCAP EVO Silver Gold Oil 450 V.

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 18,00 excl. VAT: € 15.13 / $ 16.03
If you prefer to mount the crossover components on a universal PCB instead on wood
