I was also disappointed with the frequency response. So I opened the back terminals unit and checked the crossover circuit electrical frequency response. What I found explains what the problem is. the crossover point is at 1800 Hz as specified BUT at that frequency both the bass and the twitter levels are at -11dB instead of -6dB. The crossover schematic is shown in the attached file. The inductors values are not marked. The only way that I could fix it without replacing the whole circuit, was by adding a 10uf (2x22uF back to back connected) capacitor in parallel to the 3.6uF. This change shifted the crossover level to -7 dB but the crossover frequency moved to 1350 Hz. Listening to the speakers now is so much better that I will keep this modification, unless the Klipsch company will see this post and provide a replacement crossover units.
