They are sounding mighty fine. Still breaking in, but good enough now for sitting down for long listening. They are much cleaner and lower distortion than my previous speakers, so I am happy with the decision to move on to the next chapter.
Still deciding whether to add subs or not. For normal music down to 50Hz it is not needed. For symphonies, dance, organs, etc it will be needed. The huge woofer coils make excellent bass.
North Creek 10ga coils on woofers and 12ga on the tweets. Jantzen SuperiorZ caps and the resistors are the metal oxides that came with the kit. Once I decide that I am happy with the tweeter levels then I will put some Duelund graphite resistors, or make my own from pencil leads.
The woofers have incredible detail, layers and layers deep of texture. The tweeter has all the extreme detail of a metal hard tweeter without the bite, or the distraction. I haven't really done much serious listening to strong quartets or trumpets so time will tell if these really are world beaters. But so far there is no reason to think they will not be that good.
The edges are rounded over using table saw for rough cuts, block plane for shaping, sanding and a little filler. There is lots of internal bracing, mostly corner bracing between two adjacent sides which I have found to be the most efficient kind of bracing. The boxes are very quiet considering only one sheet thick. I wanted to put the roofing membrane in them but the kind I want is not available in single roll.
I think I have a little too much stuffing, I'll experiment after break in is done. I'm using Electratube binding posts. They are very nice. Pure copper, gold plated, minimal mass and no threads in the signal path, and only $60/4.
They are playing just fine on Sol's I-15 integrated amp, 15 watts. But his I-60 will be a better match. I never thought a 85dB sensitive speaker could sound so alive and musical, but it does. The simple shallow crossover filters and super high quality parts minimize the loss of life.
Still have to stain and poly them. Then g2g.
