Got a mint pair for 50 bucks.  Good for Cubo15 or some tapped horn enclosure?  Reflex is out of question because they are boring. 

Fs 29Hz
Qts 0.28
Qes 0.3
Qms 10
Vas 280L
Bl 17,2
Xmax +/- 9mm
4 inch voice coil

So according to specs, looks like these might be quite potential drivers anyway.  Does anyone have some experience about these?

ported horn? - the Nexo SI2000 bin used a variant of these, and they were highly effective.

Make sure your drivers are indeed L 15P 200A and not L 15P 200. The RCF L 15P 200 offered different parameters and, were marketed for reflex cabinets.  

Best Regards,

These are indeed 200A models.  

That nexo si2000 looks like interesting. However I'm trying to figure out if SS15 tapped horn would suite this driver too!  Tham15 might be too tight/small (not a big difference tho, but SS15 is tuned lower).
Just wondering if this kind of high VAS driver is ok for tapped horn duty?  High compression horns are out of question for sure I think.

Input for the tapped:

Can just adjust Cubo. This one is also with chamber.
Mms is off. To be fair I wasnt sure ts, I picked some of them from 200 AK.
How is xmax calculated here?

Watch inputing there is TH1. Rear of the driver between L23 and L34.
Try to make L12 -> 0
