AB----The L-200 used the LE-15B which is a different animal than the 15A. Our friend must first make certain which he has.Then the L-200B used a different woofer, knowledge of the model number of it being too arcane a JBLism for an Altechie like me. ;-)
Follow Ups:
The woofer just says LE-15 would that make it an "A" The serial #'s are 1225 & 1226. They are in dark blue wrinkle paint & are 16 ohm.Thanks again
Matt---What kind of surround? As have a half-roll surround and Bs have a corrugated cloth.
They are a white cloth surround.Thanks,
Greets!'A' series, which IIRC was optimized for ~8 ft^3 sealed cabs, but any of these old low Fs/Qts drivers perform well in Vb = Vas, Fb = Fs vented alignments and increase the amp's and/or system's output impedance to flatten it in-room as required. If this is too big, then ~Vas*0.6 tuned to Fs is an acceptable trade-off between size and LF gain BW for most folks with space and/or WAF issues. As box size shrinks, then either you'll need a corner to gain back the lost acoustic efficiency or raise Fb to compensate.
