...unfortunately this system is 12,000km from the place I actually live...I built the system 4 years ago based on a Technics SB-RX50. The corpus consists of 24 CNC milled HDF slices, surrounded by a stainless steel wire-mesh. The rest is all stainless steel with different surface treatments as electro-polishing and sand-blasting. h/w of the ecliptic cabinet complies with the "golden ratio". I kept the inner volume and rebuild the original frequency circuit with Mundorf ect...the subwoofer is a Backes & Mueller U-Sub2, but actually you do not miss much without...
