Somewhat rare matched pair of these. Currently set up as 2-way, Electrovoice SP12 (not the lighter weight SP12B) on the low-end, crossed over to Electrovoice T35 tweeter at about 3600hz. They sound very sweet as is (the SP12 is a champ), but I do have midrange horns, drivers, and 800hz crossovers if you want to convert to a 3-way speaker. See pictures. Another pair of speakers I will miss. :-)
