Amp suggestion for large 2-way Speakers

I'm looking for amp suggestions for a pair of large 2-way speakers.  They look like passive Augspurger style, with Speakon connectors on the rear (1 for high, and 1 for low).  If you could suggest a "budget friendly" route, and "best performance", that would be helpful.  Here are the specs for the drivers:

15 Inch Drivers, 4 ohms, AES Power handling 1400W, Maximum Power Handling 2800W, 40-2000 Hz

Horn Drivers 2 inch Throat, 8 ohms, AES Power above 0.9khz 100W, Maximum Power 200W  0.5-18 khz
