No good. They are almost all quarter-wave lagged organ-pipes and the
tapered ones are so short that they are really closed-boxes or
bass-reflex.

This is more the thing:

0Nautilus

Though a TL for a tweeter is rather pointless, it looks good.

Actually, since the point of all the TLs on the Nautilus range is to
absorb back radiation without producing excess pressure on the back of
the diaphragms, they are certainly applicable to all drivers, even
tweeters. Indeed, the TL tweeter is the most widely used of them all
across the N800 range.

yes , but what price?
they look like they are made of plastic!!

They're made of a highly specified engineering composite, certainly
not 'plastic' in any normal sense. Prices range from about £1500 for
the N805 through £10,000 for the N800 to £35,000 for the 'original'
Nautilus.
