Hi all,\n\nI've retired from speaker building but I want to share this last ESL project. I don't know how I would top this one anyway-- It's the finest speaker I've ever built.\n\nOthers are building these now, using my drawings and encouragement. The labor is horrendous (no sane person would attempt it) but the journey and results are life changing.\n\nDescription:\nThis speaker is a flat panel wire-stator hybrid electrostat with dipolar bass from an Eminence KappaLite 3012LF woofer on an open baffle. The speakers + subs are 6-channel stereo with a DSP crossover.\n\nThe Eminence 3012LF woofer isn't optimal for low bass on an OB (low-Q & 56Hz Fs) but it doesn't need to be with the subs in play, and it blends superbly with the ultra-fast electrostat, and that was the priority.\n\nThe stators are state of the art 90-wire arrays, symmetrically segmented in 15 six-wire groups to function as a line source projecting a cylindrical wavefront. This setup gives wider and smoother trending dispersion than a curved panel ESL, or even most conventional speakers.\n\nThe details of how the segmentation scheme tailors the dispersion are given on my website below, along with several build videos:\n\nJazzman's DIY ESL Page\nJazzman MkIII Intro Video\nStator build video\nPanel assembly video\n* Video of the prototype playing\n\n*The prototype had a different segmentation scheme and a lower quality woofer than the final version.\n\nBelow: The Jazzman MkIII ESL and matching Ripol subwoofer\n\n\nBelow: Back view showing the amp-interface assembly and Eminence 3012LF woofer.\n\n\nBelow: Sketch showing the wire lacing and segmentation layouts.\n\n\nBelow: Stator in the assembly jig with the oak support lattice glued down over the wires.\n\n\nBelow: Completed 90-wire stator.\n\n\nBelow: Front stator being bonded onto the diaphragm, on the bike tube tensioning jig.\n\n\nBelow: The amp-interface assembly (HV bias supply & tandem step-up transformers).\n\n\nBelow: Jazzman MkIII speaker with its magnetic grill covers on.
