yamamoto 45,wavac md300b, jeff kornef 45 SET,art px25,cyrus brenneman cavalier,FI 2a3 mono blocks. Depending on your loudspeakers design these should work well I used them on my hi-eff horn riggs. Still some horns can be a bit harder to drive any info on your horns would help with suggestions. Mine are also 109 db 1 watt 8 ohms so easy load for SET which they are designed to use.
