Hi Langtuhanoi

Have you considered the Ariels?
These are one of the best Diy speakers available for a long time.
I really enjoy mine after all these years. MTM's, two way in a tower
or just simple enclosures much smaller.
It's worth to take a look at them....

Brett,
The challenger series look to be better quality than the HP15w, but I think they don't have low enough Fs, they're all around the low 40s, HP15w is ~35 Hz, probably still not low enough.

The Airdale goes down to 25Hz, so we need a 15" driver that is efficient, has largish Vas, and will go that low.

I once had a similar dream to Langtuhanoi about the old Tannoy York Cab, I ended up choosing the 10" Peerless 850146, which would be perfect for this application, but unfortunately is no longer available....

Langtuhanoi, an alternative to 1x 15" woofer would be to use 2x 10" woofers, for Hi Fi these are probably easier to get, and would give the same surface area as a single 15".

Most 15" speakers available seem to be for PA or Car Subs, not really suitable
(I'm sure someone will prove me wrong)

I see that now the big driver (15") less than others driver. It is the same performance, isn't it? and thay don't want to use the big driver again
I want the depth of sound (bass) is quite clear, so I think the big driver is designed for it

I just modelled a pair of SEAS L26RFX/P 10" woofers in Unibox,
In a 180 Litre cabinet tuned to 24.5 Hz, that looks to be a pretty good way to emulate the Airedale's size, response and tuning at the low end...

langtuhanoi,

The Airedale design is follows the old 1950s/60s way of doing things, that was what they had to do to get deep response in those days.
Many modern drivers are much better, so you can get as good or better response in a smaller driver compared to many of the old drivers (some will disagree of course...).
Most people (or their wives) prefer smaller cabinets nowadays, another reason why 15" isn't common in home audio.

So don't get stuck on a 15" driver...(of course a smaller one won't LOOK as impressive )

Well, the Tannoy York is similar to the Airedale,
you could scale it to 180 litres and tune the ports according to the drivers you choose:
