Hi Bill,
You are welcome. There are tigers out there... I see you have a 5" Wharfedale Diamond 6 midbass (they used to be the best studio monitors bang-for-the-buck. Good choice. From what I remember (10/20) years ago they were about 88dB SPL (are they made of paper, the cones?). You need a (about) 5dB att to go with a 93dB piezo, if you prefer it (for the frequency response) to be flat. Wayne use's a 0.22uF for a 4dB attenuation on the (his 1038) Motorola. Place the capacitor in series. If you use a resistor in parallel use a "only non inductive parts", for caps polypropylene only and never electrolytics because of sound quality. You can always read Wayne's Pi implementations of quartz piezoelectric tweeters on this forum.
Best Regards
