hi,

I reviewed most of them and sb21 looks very good. I am considering a built 2 way system with sb21 sdc.

When I looked the graphs it looks it can be crossed 2 khz(even 1 khz) Does anyone have experience with this?

I'll be matching this tweeter with the SB16PFC woofer early this summer. I'll post when I get measurements of the prototype box.
