Midas is a two way floorstanding speaker.
Midas is a bass-reflex cabinet loudspeaker with drivers of Wavecor .
The kit is delivered with the following drivers:
- a Wavecor TW030BD11 tweeter
- a Wavecor WF182BD04 midrange / bass driver
The loudspeaker has been developed by David Hahn.
The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a first order low-pass filter (6 dB per octave slope) for the mids-woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,2% above 500 Hz and doesn't exceed 0,5% at 95 dB at 1 m between 300 and 15000 Hz.
"What can I say: Even with "only" two 7-inch drivers, the Midas produces a powerful and dynamic bass foundation that does not get out of hand even at higher volume levels. As desired by the builder, the bass is not ultra-deep, but clearly defined, solid and very precise. The two cone drivers process the fundamental and midrange range with the necessary precision and neutrality - close to perfection. And the higher range is alle treated very well by the excellent tweeter, which does everything right in terms of both energy and fine detail. It is always astonishing what this excellent dome tweeter by Wavecor is capable of."

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 Wavecor TW030BD11 are of type polypropylen (MKP) Clarity-Cap CSA 250.

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 9,20 excl. VAT: € 7.73 / $ 9.28
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 5,60 excl. VAT: € 4.71 / $ 5.65
We recommend one board per kit (two boards for a speaker pair)
