In Reply to: RE: "So for a horn loaded driver, round up the DC resistance to the next higher standard: i.e. 8 or 16 Ohms." posted by b.l.zeebub on July 22, 2016 at 16:15:01:
Some of the specs for the JBL 2426H/J linked by DJK here were derived with the driver driving a 25 mm (1 in.) diameter terminated "plane wave" tube, which would have a different acoustical resistance (as seen by the driver) compared to some of the other specs derived with the driver on a horn. The plane wave tube standard was set so that different drivers performance could be compared with a standard load separate from whatever horn the driver could be attached to which was not necessarily standard. "It pays to read the instructions" as my wife sometimes reminds me.
