I’m pleased to announce that my new panels finally arrived, after a six month wait. I was worth it!
However, a bit of a surprise- what I thought I had ordered would be identical the original panels, I now have 845 panels! While unexpected, perhaps a blessing. The Bass Focus design definitely superior, but the bigger panels also go deeper and are more efficient, presenting an easier load for my Pass Lab XA-60.8 amplifiers.They no longer strain on higher loud notes, and handle bass with aplomb. Overall, a great step up- the best sound ever in my 20+ years of Sound Labs!
Roger noted that many U-1PX owners have done this, and sent photos.
