Waynes new crossover board build took a backseat to my infatuation with the ART active but I was almost to the point of bagging it and going back to passive.
However, I found an opinion on the Curcio site this A.M. about not using passive attenuators to drive active crossovers due to capacitance issues. I have no idea whether or not that was the case with mine but when I replaced the passive I built with the ARC LS-1 that had been on the bench, things improved markedly.
I then got serious about fiddling with the attenuation controls and found a setting that totally eliminates the shout or screech or whatever (best guess is just a CH more than 14dB) and moved one speaker back 1/4". Spkrman will appreciate that the treble is now far 'easier' and the overall sound quite natural. I would dare to compare it with the XLHs driven by the KR 1610.
This is good. No, this is great! That LS-1 with a few mods is killer. The image is now far less diffuse, the lost inner detail is mostly back and the dynamics are first rate. My main complaint, shower stall ambience, is also gone.
I will build the new boards and implement them very soon but this $95 box is pretty damned good.
