Not a suitable combination.
Efficiency match is ok, but the impedance match is poor. Look for an 8 ohm speaker for this amp.
If you want to keep the speakers, then you need an amp capable of low impedance loads, which is not any SET amp, nor most tube amps in general.
There are some tube amps that can do it, like a Wolcott, but under 2 ohms is generally SS territory.
