your looking at high efficiency speakers. that amp will output 15wpc from what I googled. so anything 94db and up will work. Zu audio, Omega, Tekton I believe have entry level stuff in that range or very close. then your into vintage stuff like older Klipsch Cornwall, Heresies, Forte's they will give you high efficiency as well.
Also you can use just about anything but your volume level will be lower and it will be harder on the amp if you go to low an efficiency speaker, but they will work.
