They are for 15" drivers. Im not sure of the recommended drivers but im sure staiper can tell you if you send him a PM

in terms of bang for buck the fane 18 xb has a long history of usage in
dub and reggae sound's scoops. i think that they have a lovely rich and
warm tone, and have heard others say the same.

if i was to build scoops now though staiper's 15s would be the ones.

PD might be expensive because they dont pay their workers in thailand 2cents per hour..

Note that when Ive modeled front loaded rear sealed horns,these drivers DONT work well on scoops-the reponse turns into a rippley mess,meaning its not well matched to the horn. Instead I used MLUTIL and found driver which instead provides its own damping by its suspension(spider) on AA 'GM' posted the ideal driver for a old bassmaxx/scoop cabinet.

will the fane 18xb be suitable in the superscooper tho?

Are the t/s specs similar to the driver used in the superscooper?

 

It's all about the motor strength for bass horns (the other parameters are nice for HF extension or findign an optimum) but I wouldn't expect a kicker driver to hold it's motor strength linearily for too much excursion and mike will well know what happens when you model up a Motor strength <5 (using square root formula) in most bass horns.
