Well, the options are out there.
1) rebuild what you have if you can find someone to do it right for a price you can afford
2) Dale Harder rebuild or new drivers
3) OHM upgrade
If it were me, I would not dismiss the OHM upgrade option until I did an in home audition. You could have brand new well supported speakers that have more in common with the old Fs than not + are competitive with modern SOTA speaker lines, yet still totally unique.
BTW OHM was a Tech Hifi house brand. John Strohbeen, the current owner and main technical guru at OHM, used to own Tech Hifi.
I always preferred all the old OHMs sold at THF, including the conventional box designs like the L and H in particular over most other brands sold, including EPI, though EPI was probably a strong second in the pack with a few others.
My main speakers these days are a pair of OHM f5 series 3 which are recent generation OHM Walsh CLS drivers mounted on refurbed OHM F cabinets that I picked up for a fraction of retail price from OHM a few years back taking advantage of sale price for refurbed units + full trade in value for older OHMs.
I also run a smaller pair of OHM 100 series 3 drivers mounted on refurbed Walsh 2 cabinets, a pair of Dynaudio Contour 1.3mkII monitors, and a pair of small TRiangle Titus XS monitors. I also still run a refurbished pair of OHM Ls, my original first good speakers from TEch Hifi years ago that I upgraded myself with drivers and parts from OHM and elsewhere, and a really small pair of Realistic Minimus 7 speakers out on my deck during warm weather months.
