I understand.
The Seas 11-FG is a "mini-woofer" though.

Why not buy midrange speakers in the first place instead of butchering poor innocent fullrange speakers?
That does not answer the topic question does it?
FWIW,
I have a pair of DX-55 cones without whizzers. They exhibit a large peak
in the upper mids, and I did not find them to be any improvement.
Peak disappeared with whizzer removed?
I am asking since my system now becomes a 3-way (BLH DX4 up to 800Hz, TD2001 till 8kHz and a T900A beyond 8kHz).
Eg. with double bass recordings (sound fantastic by the way), the whizzers have an annoying rattle to the carefull observer/listener,
"Whizzer" cones are blamed for the flaws of the cones they are planted in front of. My favorite driver ever was the SEAS 11FG (I think) which had a "whizzer" almost as large as the cone behind it. Wonderful. I should have save a pair from back then (1980s)
Wouldn't work for me due to low efficiency and high QTS.
It sounds a bit drastic, can you damp it in some way if it's rattling?
That's how I found out.
Now I am looking for someone who did it
Peak disappeared with whizzer removed?
Not the way I read it: Nelson appears to be saying that he's got a pair of DX55s without the additional sub-cone / whizzer & they have a large peak in the upper midrange.
Horning run Lowthers modified with the secondary cones removed. They do not provide any measurements however, although their speakers are well received amongst those who like that sort of system.

I have never heard Lowthers, although I assume they will have the same sort of Fostex/other fullrange sound with tons of resonances and energy storage, sort of a paper/cardboardy mess. Loud at low power like only peaky speakers can be. Am I wrong?
BTW, the SEAS fullrange was probably this:
Seas Breitbandlautsprecher 11F-LGWD

'couldn't tell you, I've never heard any Horning product. I simply said that they use Lowther units, sans whizzer cones, and that they are well-recieved by people who like that sort of speaker that uses a large cone wideband driver as a midrange unit. I couldn't live with Lowther drivers myself, if used as direct radiators -the lower HF peaking most have doesn't suit me. That said, as originally designed, Lowther drivers were not meant to be direct radiators, and in any case, it's not for the likes of me to tell people what they should or shouldn't like.
FWIW, from a few, er, moons ago: 6moons audio reviews: Hørning Hybrid Agathon Ultimate
I'm not entirely convinced about using Lowthers as midrange units -modified or not, that's not really what they were designed for. Still, some do seem to like them, so it may be worth considering if you're already inclined in that direction. In theory, it should improve off-axis response up to the lower treble regions.

Are they not just using the Lowther as a midrange?

(1) This page records adventures with a ~similar 8" driver
Wharfedale Super 8
Basically the 'naked' cone has a big 3-4kHz peak, and the whizzer smears this out to become a broader series of ragged peaks and notches.
(2) Post 11 shows the hackwork I did to turn another bad fullrange driver into a half-decent coaxial.
EDIT: here is the link

I can't see what you'd gain by starting with a Lowther. There are pro midbass drivers that are better and cheaper.
