Tannoy 15” concentrics

I have decided to give these larger Tannoys a try. I would like to ask for advice for specific driver models, version to look for. Trying to Stay away from the vintage ones that fetch crazy prices.

I have auditioned CPA15’s and those sounded good. Do they use some of the better tannoy 15 drivers? What driver model to hunt down?

Will be using subwoofers.

I know ZM and possibly others members on this forum could provide some insight?
Thanks
 
That's going really far, but here's my point:
Sometimes I see their 15s" for sale. Like the PA and install versions that are still not crazy expensive -- 3836 or 3804 --from CPA 15 or i15.

They are newer than the HPD, Gold and Red and whatever. I don't want to automatically assume that the newer versions are better. But maybe they are. So that is why I ask.
I am not collecting. I am trying to get help choosing the better Tannoy 15" for a project -- pair of mains that will be aided by a pair of subs.

Sometimes older stuff is better but not always and usually not in speakers. Again, that's why I ask if this applies to Tannoys. Looking at their current product line does not help because some of their PRESTIGE models use the TULIP waveguide and some the PEPPER POT. I cannot see a relationship between the waveguide and class of driver.
