15 ohm speakers is an odd one. i don't know

Tiny solid state amps can handle weird ohms well

speaker impedance capabilities for amps are minima. ie, an amp might say to use 8 Ohm minimum speakers, so you shouldn’t use 4 Ohm speakers with that amp but higher than 8 Ohms is fine. the lower the impedance, the more demands they place on the amp by drawing more current through the output circuit.
90dB/W is pretty efficient so you won't need a huge amp to get decent volume. in short, practically any hifi amp thats ever been sold will be capable of driving those speakers.

Thanks all, I have this already so I will use that https://a.co/d/i4zXRx3
