If you're building the amp then you can build with your speaker's impedance in mind (increase bias).

I run paralleled New Large Advents (3 ohm dips for sure) with an F6 (1.3A bias)
No problem for that amp.

F5, F6 and M2 give more power into 4 ohms.

The others, less.

All have somewhat more distortion into 4 at a given wattage.

Not a firstwatt amp but Sony Vfet2 is a very good amp for 4 Ohm speakers.
Also Burning Amps with push-pull source follower output.

It will also depend on speaker sensitivity. I have a 4 Ohm speaker that's over 100dB/2.83V. That speaker never sees more than 3V peak. So that speaker is not a problem for virtually any firstwatt amp.
