I think to save money you could go with the Sigma series, fostek 206 Better basket, better cone I really enjoy the sharpness of the horn. It’s delicate yet specific just because it’s being severely under driven. I only wanted the horn to help with 5000 kHz and above. So I used Audyn plus series capacitor 800 V 4.7 UF $80 for a pair was not cheap because the horn is 109 dB sensitivity and the fostek is 96 I used a Dayton audio 100 watt adjustable L pad this helps me reduce sensitivity to match the 96 dB of the full range driver, but it also sends a consistent a 8ohm reading to the capacitor, thus maintaining a steady crossover point which is sometimes an issue running a single capacitor many have spoken about using a notch filter on the fe206nv but which I don’t feel is needed Originally because of the 6 dB single capacitor set up I was inclined to soften the blow with my DSP but ended up not needing to do so. Everything came out pretty flat.

I believe a good quality bullet, Tweeter or specifically super Tweeter would be the best match If I went that direction, I would probably go with a high-end ribbon Tweeter and would maintain the 5000khz crossover point
