I’m one of Ralph’s dealers and also a speaker manufacturer. If by "the options" you mean "speakers that work well with Ralph’s lower-powered amps", that depends in large part on the specifics of the speaker’s impedance curve. Sometimes it is possible to tweak the impedance curve a bit without otherwise affecting the speaker. The Zero Autoformer from Paul Speltz is one way of doing so, and there are other ways which are also benign.
If you have a particular speaker in mind, shoot me an e-mail or a message and maybe I can offer some thoughts.
Eight ohm speakers can work very well with Ralph’s smaller amps if they have compatible characteristics, so you are not limited to 16-ohm speakers.
