My old system

1991: First contact with Dr. Bruce Edgar's articles

• That time, my system (built back in '95) consists from:
• Klipschorn Bass unit as active subwoofer (fc-100Hz)
• Midbass: 8" Eminence EM8-100 in ported enclosure (doh)
• Mids: Audax 6 1/2" Audax PR38TSM... in closed enclosure
• Heights: Fostex FT66H (before FT50H)

1991: First Tractrix Horn, built for the Audax midrange

1992: First major modifcations. From now:

• Klipschorn bass
• Downscaled La Scala bass unit for 10" driver (100-500Hz)
• Dynaudio D54 in a 300Hz Tractrix horn (500-5KHz, based on the Edgar Midrange Horn article)
• Fostex FT66H tweeter (5k-20KHz, the big T950A is not connected).

Soon it became clear to me, that there is so much more potential in a system entirely equipped with horn loudspeakers. I decided to go on.
The small LaScala's were the next items to be replaced:

The Tractrix Midbass

Later with a new rack:

But soon, new incidents influenced my tinkerings.

Fostex D582 compression drivers

150Hz Tractrix Midbass

I was very pleased with the results since it was a big inprovement compared to the previos setup. These pictures were taken before the remodeling of our living room. You can find the plans for these horns in the download section.
