Re: EV Deltamax DML1152 cabinets with JBL drivers - how to approach the seller?
I don't know about the later boxes, but the early DeltaMax systems used an EV DL15X woofer, not the EVX series. The DL15X fifteens were reasonably efficient but essentially an extended pole piece variation of the EVM 2-1/2" voice coil speakers. Although the EVs were loud and had good midbass response, the JBLs would probably provide a little bit more "thump" in a two-way application, and do it with less mid cut and bass boost.
Except...
the whole reason for having a DeltaMax (back in the day) was to use the analog controller (and its sense lines) so you could run the living snot out of those guys without them expoloding into magnetized shrapnel. The controller provides limiting and equalization to the specific original drivers.
Replacing the high and low drivers and eliminating the controller makes those "DeltaMaxes" just another pile of generic trap boxes. Overpriced ones, in this particualr case.
