Don't forget "Welcome to the Machine" It's awesome that the new Mag can play that high. Are you going to post distortion plots, frequency response, t/s parameters? I just might go back to a simple 2-way (no 8" midbass) since my PPI PSC-221 will help with the lower frequency localization. How high is sensitivity? I am interested in using some pro audio midrange drivers (18sound) and the Peerless HDS, which are both around 92 dB @ 8ohms.
