Just for fun I increased the tweeter output cap (C2) to the 25uF value all the calculators give for 1600kHz. Added a 3.3uF Auricap to the 22uF Obbligato oiler.Only a few hours on them but it sounds horrible. Tinny. Makes the BatSpeakers sound like Fostex. Guess we know someone who'd like it, right Colin, Ron?
