A horn of 94 cm diameter supported by an 18 inch woofer: that's the Eggo 1.

The Eggo 1 was already shown at the HiFi Music World in Gelsenkirchen, Germany, as an active loudspeaker (price upon request). For this speaker Thomas Schmidt designed a passive crossover.

For low frequencies the 18 inch woofer Faital 18 FH 500 is used, featuring a driver free air resonance of 30 Hz.

For mid and high frequencies the Audaphon horn H94-2 with 94 cm diameter is employed. The horn is driven by a Faital HF 200.

The crossover is an 18 dB/octave type, whereby the slope is considerably reduced by additional resistors outside the crossover area.

An excerpt from the Klang+Ton review

... "... These areas didn't pose any problems during listening; merely recordings with exaggerated tops were reproduced by the Eggo 1 with some presence, like all other neutral sounding speakers. That's precisely the point of interest. Contrary to all expectations by exited listeners regarding such a big project, this speaker's performance is as relaxed and neutral as possible. There is no colored cheekiness, no boom and hiss and, above all, no cheap showmanship. The Eggo 1 is a speaker that can be fed with any kind of music with the volume set to any value - just sit back and relax. The woofer maintains a low profile and contributes its part to the pleasant team play, but can get cracking if the source demands it. This needs to be experienced - a small speaker is just not capable of doing it; even though the lab results prove that the Eggo 1 doesn't have a lot of low bass - the advantage of the enormous surface area comes to light.

The transition from woofer to horn is seamless, timing is perfect, without any impertinence by any driver. Despite its size the loudspeaker performs homogeneously and incredibly relaxed - even at a two meter distance. This unobtrusive style of play even remains when turning up the volume - at times one doesn't even realize how loud the music is; that's how relaxed the Eggo 1 is. Some of our colleagues present seemed to be reminded of the old Voice of the Theater, having had a similar nonchalance - that's certainly a compliment!"


Our kit consists of

  • Audaphon horn, 94cm, for 2inch driver
  • Faital PRO Throat HF200, 2 inch
  • Faital PRO woofer 18FH500
  • 3 pcs. Bass reflex tube HP100
  • Binding posts, 4 units
  • 2m Speaker cable 2x2.5 mm2, transparent
  • Allen wood screws, black, 5x30 mm, 8 pieces
  • Plan for DIY kit

the crossover components (right),
to be mounted on a small wooden board.

  • electrolytic capacitor, unetched, 5.6 μF / 70 Vdc
  • electrolytic capacitor, unetched, 33uF / 70 Vdc
  • MKP capacitor 4.7 μF / 400 Vdc
  • MKP capacitor 6.8 μF / 400 Vdc
  • 2.0 mm air core coil, 0.68 mH/0.13 Ohm
  • Core coil, 2.2 mH/0.21 0hm
  • I-core coil 2.7 mH/0.19 Ohm

  • Ceramic resistor 6.8 Ohm / 20Watt
  • Ceramic resistor 8.2 Ohm / 20Watt

Info: Instead of the suggested metal oxide 10W resistors we deliver 20W ceramic resistors because the other ones get very hot, if higher power is applied.

Kit without cabinet, price per speaker - not 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.. I-2767, price per unit: EUR 7,60 excl. VAT: € 6.39 / $ 6.96
We recommend one board per kit (two boards for a speaker pair)
