Wayne,
What better way to amuse myself while "killing time sanding" the enclosures, than to test/burn-in these new 4 Pi Pro xovers...on the jbl 4648A-8 based HT fronts. Just hooked up the coil (1.0 mH 14 ga.) in series with the 2226J woofers (no cap, OK!), HP is text book 1600 Hz. 3rd order w/ Pi pad/comp of 12 dB, feeding altec 902-8B's on 511's. Initial impression is very favorable in comparison to "normal" 600 Hz. BW's or the series 1200 Hz. 1st order I have also been using, but they both ran the HF "uncomped", just shelved 12 dB. I have some 0.8 mH 14 ga. coils to try later, for use when the 4 Pi Pro's are being tested/put in service. Sam
