Just found this spanish Beyma 10AGN driver, looks very good for OB, QTS=1,32     Retail price is 44 Euros, unhappily it is not a 15 inches, just 10'' with a steel plate basket, but the Freq Curve looks good for a boxed loudspeaker.

The 150Hz-600Hz dip will negatively affect the musically satisfying midbass frequencies . But if you could engineer the bass peak at 120Hz to compensate for baffle step to some degree then it could be a blessing in disguise.   Beyma makes good drivers.

This valley or dip in the midbass area is very common in the Beyma woofers, midranges and fullranges, some have minor downhills, this 10AGN have a wide low area really.
Maybe stuffing the inside box with something suited, could rise some bass freq.  This drive is old in the Beyma catalog and they do not fix it, nor release a new better sucessor driver, nor cast frame it have due the low price.   The interest is to sell...
