Help with HiVi F6 in a 2-Way

[GOR3]

I just acquired a pair of HiVi F6s. I'd like to use them in a small bookshelf 2-way system. Does anyone have experience with these? What tweeter do you recommend at the same price point, i.e., around $50? Any other comments or suggestions?
Thanks,
George

Looks to have bad odd order distortion right between 1-2khz. Something like a RS28 crossed as low as possible, or even a Vifa TC9 or TC7 would probably produce the best results.

Here are a couple designs from the PE Tech Talk forum.

Hi Vi F6/ RT1 Planar crossover

My first "from scratch" build (with help)

And from Swans/ HIVI.

I have some more from Swans and a LEAP design for the F6/ Seas 22TAFG but no links. Don't be afraod of this driver, it has had some very good reviews and a nice midrange.
If you want more info email me.

Hi George

From F6's fr plot, optimum crossover is about 2kHz - 2.2kHz.

You may want to consider Seas 27TDFC. It can be crossed as low as 2.0kHz.

I would avoid HiVi RT1C. That planar sounds nice but it's minimum crossover is about 4.5kHz. I've crossed it at 3.5kHz before but that's pushing it.

Mike
