Classic gear from yesteryear; vintage audio standing the test of time.

maaate, you just described the OB in the OPost!

It would need to be measured for its bass roll-off due to the baffle and the bass driver would need a Low-pass to blend. 1st or 3rd order

The ribbon should be rolled in to match the WR driver's own roll-off.

And the WR driver needn't be filtered at all.

Level matching would be necessary, too. But that's not real hard if you choose drivers to be in the ball park. Matching dispersions, so they don't jar in the pass-bands is a biggie too.

IME the 126en sounds best if left alone, except for some parallel RC to flatten the inductance rise it just will have. IF you are going to filter any WR cone-only driver, L-rise eq is vital IME&O.

I've yet to hear a whizzered WR driver I could stay in the room with.
