As above. someone I know has a pair of unloaded superscoop cabinets going begging. I'm wondering whether the 15" faital driver would work in them (drivers I already have, but do appreciate I'd have to adapt the box to take a 15" instead of an 18"). I guess they perhaps wont go quite as low as the PD1850 but otherwise would there be any drawbacks?
I think its a pair of these:

No expert at all here but the numbers do seem quite different. Maybe it would just be a waste of time, but with (probably) little else to do over winter I could try / measure / see what happens.

I suspect it wont work, or rather, wont have the desired effect which is higher output per driver but with no detriment to the sonic response.
The comments on various threads all talk about scoops needing kick bins > 80hz as well. If that's the case then it starts being a lot more of a faff.
As you know Chris I'm a big fan of the tone, sound, and portability of these existing subs. They are great little units but it will get to the stage at some point where doubling the output will get expensive.

Yeah, they're good little boxes.
In terms of more output per cone, I'd look towards THs. The good ones are getting 35Hz-120Hz. There was a 40Hz tapped horn based on the Orthorn, but for 15" drivers (Oth40C). The Hornresp inputs have been lost, but it should be possible to figure them out again.
IMO, 40Hz extension should be the minimum goal, which unfortunately rules out the THAM15.
I've thought about heading in a similar direction with my 15"s. It might be possible to get to a compact-but-tall-ish tip-and-roll (like you would with a sack trolley) design, which would be cool. Easy to transport, and not as heavy/bulky as the 18" designs.
Time to fire up Hornresp.
